Power Cable Accessories: 3 Things to Know Before You Buy

Power cable accessories are important tools that help to distribute power among devices in a safe and effective manner. However, because of the wide variety of these accessories, it can often be confusing to know which one is the one you need. When purchasing accessories, consider these three things, quality, location, and specifications.


  • Quality- Getting The Right Accessory

Each company that develops power cable accessories have their own strengths and weaknesses. This means that, despite having two similar products, one brand might be more suitable than another for a certain project. An easy way to determine what type of accessory you need is to find out which accessories are meant to be used in certain environments and what the different amounts of electrical current they carry. From there, a sales associate can assist you in fine-tuning your search more effectively and let you know which brand is the best for your needs.

  • Location- Where Will It Be Used?

So many people overlook location when they’re deciding on what type of power accessory to get. This is a major mistake! Location is one of the most important questions to ask yourself about before you purchase because everything else depends on it. For example, outdoor use cables will be more flexible and made from hardy materials that can withstand wear and tear from outside environs and situations.

  • Specifications- Wattage Rating And Other Concerns

All electrical cables and cords have small metal wires that are meant to conduct electrical currents. The thickness of the wire will let you know how much current, or wattage, a certain wire can carry. The wattage rating is the amount of wattage that a wire can safely handle. It’s recommended that you know this important number before you use power accessories, particularly if you’re powering multiple devices from one source.

Most of the information that you’ll need can be found on the labels and product specs of a particular accessory. However, if you’re uncertain or don’t understand, it’s always a good idea to ask for help from someone who is knowledgeable about the various products.


Difference Between Type W and Type G Power Cables

The Type W and the Type G power cables are very similar. They are used for nearly the same applications. These are industrial strength power cables. The cables can be used on all kinds of job sites to give power to machinery. They can handle 2000 volts of electricity and have rubber insulation around them.  But there is in fact one main big difference between the Type W and the Type G power cables.


Each of these cables is a 2000 volt rubber power cable. They have thick insulation for industrial job sites. Both are rugged enough to be run over by trucks and dragged across rocky areas of job sites. This makes the cables not only perfect for jobs at home where that much power is needed but also for job sites. Industrial sites that require a lot of power may also require their cables to be rugged and durable because of the demanding and dangerous environment.

Type W Power Cable

Type W Power Cables Type W cables have no additional ground wires. There is a same size green wire in 3 conductor cables and higher. The different colors of the wires help to easily identify each wire. The Type W cables are made ideally for industrial to light to medium duty mining applications because of it heavy duty and durable rubber jacket. It also can be used for AC systems, mobile and portable electronic equipment. This rubber jacket on the cable can withstands severe environmental conditions, as well as exposure to oils, acid, alkalies, heat, moisture and most chemicals. This shows that this cable really can handle anything, allowing it to be perfect for messy and hazardous industrial settings.

Type G & G-GC Power Cable

Type G Power Cables Type G and G-GC cables include additional ground wires over and above their conductor count. If there are 3 main conductors there are also 3 smaller size ground wires. And if there are 4 main conductors then there are 4 smaller size ground wires. The “GC” stands for ground check. The G-GC cables are known for having an excellent resistance to impact. They are made with a cable core bound for superior flexibility and toughness. They are also made with a rope lay stranding to maximize the flex life of the cable.

The difference between the Type W power cables and the Type G power cables is the ground wires. The Type W cables do not have additional ground wires. While the Type G cables do. The wires inside the cable are both colored and have numbers imprinted on them to be able to tell what a conductor is and what a ground wire is. Other than the ground wires these cables are generally very similar.

What Is Type SC Cable? Characteristics and Attributes

What Is Type SC CableType SC cables are also called stage lighting cable and entertainment cable. That is because of their typical applications. They are used in all kinds of entertainment industries including night clubs. These cables are UL and CSA approved. This lets the customers know that they are getting a trustworthy and high quality product every time. They are also approved for temperatures reaching 105°C allowing the cables to be used inside and out.


These type sc cables are used usually in the theater or the entertainment industry. They are used in television, night clubs, motion pictures, mobile communication vans, spotlights and sound systems. This is where the cables get their names from. Because of these applications they are typically called entertainment or stage lighting cables. These cables are great for applications that only need temporary power. It’s used outdoors and can be coiled and uncoiled when needed because of their flexibility.


SC cables have just one single conductor. They are a rubber cord generally used to hook up lights outdoors in the entertainment industry. The cables are made with a fully annealed stranded bare copper in the center. The insulation is made of the Super Vu-Tron in black. The Super Vu-Tron makes sure the wire is sunlight resistant. It is also designed to be able to withstand severe environmental conditions. The cable can withstand exposure to oil, acids, alkalies, heat, flame, moisture, and chemicals. Making sure so that no matter where you need to use this cable it can handle even the toughest conditions.

Their Importance

The stage lighting in a production is just as important as every other part of the performance if not more. How many people would really like to go see a play in complete darkness? The stage lighting is very important. And even more important than that are the cables that are used to hook up all the lights. The thick wires are used for large power surges while the thinner wires connect the lights to the controls. The lights need to not only be connected to the power supply but the controls as well as dimmers and more. The lights are an intricate part of a production and the entertainment cables are the perfect product for to get the job done.

The entertainment, stage lighting cords are both names for the Type SC Cables. These cables are important and often used in the entertainment industry. They are used to hook up lights to power sources as well as controls and to dimmers. They are extremely flexible so that they can be coiled and uncoiled as often as needed. They also have a very durable insulation around them so that they can be used both indoors and outdoors.

3 Multiconductor Cable Jacket Options

1. PVC

3 Multiconductor Cable Jacket OptionsPVC is the most popular material used in the wire and cable industry to wrap multiconductor cable. PVC comes with many levels of protection against environmental conditions which each come with a different level of pricing as well. For instance, you might find a PVC cable rated for indoor use and then find another PVC cable rated for outdoor use. Electronic multiconductor cables are used in electronics, devices and appliances, so there’s no need to over protect such cables because they will simply be over-priced.


PTFE insulation is used for multiconductor jackets when the temperature of the application increases. PVC cables are rated up to 105°C and PTFE cables are rated up to 200°C. PTFE cables are much more expensive so be sure you actually need the upgraded version.

3. Rubber

Rubber jacketed multiconductor cables are built to be tough and flexible. They’re used outdoors, in garages and in small shops to deliver power to equipment, generators, welding machines, power tools and more. They are manufactured with the same material as an extension cord and sometimes referred to as portable cord cables.

There are many different jackets available for multiconductor cable that depend completely on the environment of the application. Be sure to tell your supplier how and where you’ll be using your cable so that they can fit you with the most cost effective cable for your situation.

3 Types of Single Conductor Power Cable

Single conductor power cables are used to connect portable equipment and tools in single phase applications. Welding machines, locomotives and stage lighting equipment are all examples of single phase power cables and they all have similar designs.

1. Welding Cable 600 Volts

Welding cable is the most basic type of single conductor power cable but it’s still complex compared to typical electrical wire used in homes. It’s complex because it uses flexible copper strands to increase bend ability and a flexible rubber jacket for protection. Welding cables comes in multiple color options but black and red are the most readily available colors.

There is also an upgrade version with UL and CSA approvals called Super Vu-Tron cable. It has more flexible copper strands and a more protective orange jacket. Super Vu-Tron cables are used in industrial welding machines compared to shop and garage welders.

2. Stage Lighting Cable

Stage lighting cable is used to connect lighting equipment for theater shows and outdoor lighting. You might see stage cables when you go to a concert or anytime you see overhead lighting. The construction is similar to welding cable because it’s flexible as well but stage cables are more protective and UL approved. Typically, they are laid out on the ground traveling from the power box all the way to the lights which means they will be dragged across the ground and people may step on them. Added protection makes stage cables unique to their field.

3. DLO Cable 2000 Volts

Diesel Locomotive Cables are used outdoors for industrial applications that connect large amounts of power. You might see DLO cables on big construction sites that require higher voltage levels that welding cable cannot handle. 2000 Volt cables are also used for oil rigs and locomotives. They have a double insulated jacket for added protection and voltage, and they’re used outdoors in severe environmental conditions. DLO cables can be run over by equipment and dragged across rough terrain without being damaged at all.

Portable Cord Types and Information

Portable CordPortable cord is a type of cable used to hook up power to equipment that moves from place to place. For instance, a welding machine can be used in your shop or it can be transported to another shop to be used in the same manner. “Portable” equipment uses portable cord cables for a connection. Here are some reasons portable cord is a better fit for your portable devices:

1. Flexible

All portable cables are designed to be flexible because they are handled each day by the equipment operator. That person will need to uncoil the cable to use it and coil it back up for storage. They will need to bend the cable around corners and fit it into tight areas. For those reasons, an inflexible cable would not be handy at all.

2. Rubber Jacket

There are usually letter that describe your portable cord such as SJO, SO, SJOOW or SJTOOW. Each letter stands for something that describes a characteristic of the cable you have.

S – Service Cord
J – Junior (300 Volts instead of 600 Volts)
T – Thermoplastic Jacket (cheaper construction with less flexibility)
O – Oil resistant conductor insulation
O – Oil resistant jacket
W – Water resistant jacket

If your cable says “SJO” on it that it doesn’t have a “W” for Water Resistance. If you cable does NOT have a “T” in it than it’s automatically a rubber jacket. Thermoplastic material is a cost effective approach if your application doesn’t need as much flexibility.

3. UL / CSA

UL stands for Underwriters Laboratories and CSA stands for Canada Standard Association. Both are third party companies that approve the voltage, temperature and safety rating of the cable. For instance, if the manufacturer states that their cable is rated for 600 volts should you automatically agree with them? No, a UL/CSA approved cable has already had a second approval conducted to make sure that you receive a cable that has been double checked for quality performance.

Call Us! Ask questions! We have answers for you that might find you a cheaper cable. If you purchase for a large organization we can find you cables with UL, CSA, CE, RoHS, REACH, MSHA approvals and more!

Industrial Power Cables Rated For 2000 Volts

Industrial power cables are not for a typical home owner looking for a power cable to hook up a generator but they are very similar. Both types of cables will have rubber insulation and a rubber jacket but the industrial size cables will be larger, more powerful and much more durable than those used in homes and small shops.

SOOW Cable (Home Owner) VS Type W (Industrial)

SOOW Cable for GeneratorsSOOW is a typical generator cable used to hook up a generator used to power a home, garage or small shop. SOOW cables are rated for 600 volts and withstand a decent amount of impact that happens occasionally throughout the life of the cable. Buy SOOW Cable here >>

Type W Industrial Power CableType W is an industrial power cable used in much bigger applications reaching as high as 2000 volts. Generators on these sites power large equipment that run on job sites without a power source. While on an industrial building site, a Type W cable can take on severe impact throughout each day. It will need to be protected from being dragged across rough terrain, run over by trucks and equipment, and possibly tough environmental conditions. These are all good reasons to have a more protective jacket to make sure the copper conductors last longer in order to limit replacement costs down the road. Buy Type W Cable here >>

Type G and Type G-GC Cables

Type G and Type G-GCType G and Type G-GC are both very similar to Type W because they all have a 2000 volt rating, similar temperature ratings and identical jacket protection. There’s additional, smaller gauge size, ground wires included with Type G and G-GC cable while Type W doesn’t have any additional grounds. There are 3 or 4 grounds with each cable depending on whether it has 3 or 4 conductors. The amount of ground wires will always match the amount of conductors for those applications requiring grounding. Buy Type G and G-GC here >>

DLO Cable

DLO CableDLO stands for Diesel Locomotive and it’s a 2000 volt single conductor industrial power cable. It’s used to hook up diesel locomotives, oil and gas drilling rigs and other machinery needing a single conductor only. All of these power cables come with very flexible strands and flexible rubber insulation especially when compared to standard electrical cables. Electrical cables are installed and forgotten about while industrial power cables are used each day, so the flexibility makes it much easier to handle on the job. Buy DLO Cable here >>

Please call if you’re looking for a high voltage power cable. Many cables we sell reach as high as 35,000 volts in single and multi conductor versions. We also keep home owner size cables in stock with exact-cut-lengths for a no-waste installation.

DLO 4 AWG Electrical Cable

You might need DLO cable if your application has to do with diesel locomotives, oil and gas drilling rigs or telecom power supply. DLO stands for Diesel Locomotive which is the main application for it but it has very good approvals and ratings for industrial power equipment that gets inspected on a regular basis.

DLO 4 AWG electrical cable is rated for 2000 volts due to its dual insulation. It’s manufactured with tinned copper strands which makes it more flexible than other types of electrical cables such as THHN THWN wire. The insulation also makes it more flexible because rubber will help it bend easier than typical PVC insulation with a nylon coating.

One thing to remember when deciding which cable is best for your application is to realize that a 4 AWG wire is a 4 AWG wire. No matter what stranding option it has to make it more or less flexible it will still have the same diameter and transmit the same amount of electricity. The stranding options are geared towards flexibility because as copper AWG sizes get larger the copper becomes harder to handle.

Applications that require electrical wire to be sent through conduit or snaked through a home or building will be manufactured in a less flexible way. A stiff THHN THWN wire being pushed through conduit will glide right through with less of a struggle compared to a flexible welding cable that will get bunched up as it’s being pushed.

 There are a few cables very similar to DLO cable such as welding cable, Type W and stage lighting cable because they all have rubber insulation. They are considered portable cord because of the rubber and they each vary slightly with temperature, voltage and approval differences. DLO 4 AWG cable stands out with a 2000 volt rating and all approvals needed to pass inspection such as UL, CSA, RHH, RHW, MSHA and RoHS. These approvals are stamped onto the jacket to prove that UL, and the rest, have tested and approved it as compliant to the temperature and voltage ratings.

Engineers are continuously improving their cables and creating new ones to supply any possible application with a specific cable. Once they make a single conductor portable cord rated for 2000 volts, such as DLO cable, someone else will need the same thing rated for 3000 volts. Make sure you speak to your wire and cable suppler about your application so that you’re positive you’re using the correct wire with the approvals needed to meet the NEC code.

The Advantages of Using Portable Power Cord with EPDM Insulation

The acronym EPDM can stand for a lot of different definitions, but as rubber insulation, EPDM is defined as one of the best insulations for portable power cords in the industry. Portable power cord EPDM Insulation provides all of the following advantages:

  • Exceptional ability to resist damage caused by harmful ultraviolet rays and other weather conditions.
  • Can withstand temperatures from negative 200°C of up to positive 175°C.
  • Stable resistance to moisture and vapor
  • Thermal conductivity maintained at a stable low level
  • Does not absorb too much water due to its structure
  • Fire-resistant and self-extinguishes flames

There are many different types of Portable power cord EPDM Insulation that you can find online and most of these are manufactured both for indoor and outdoor use. The EPDM insulation on the portable power cords also provides better flexibility for the cords so that it can be used for industrial equipment that require heavy use, as well as for use as extension cords when needed in marine docksides, deep mines, for the sound equipment on a large stage, and many others. There are also portable power cords with EPDM insulation that are made specifically for use in vacuum cleaners, food processors, hand tools, other home appliances like washing machines, as well as medical and office equipment.

With all of the various ways in which portable power cords with EPDM Insulation are used, it is no wonder that it is priced heavily, from somewhere around $0.5 to $50 for every meter. Some of the more popular characteristics of the portable power cords that are insulated with EPDM insulation are:

  • High amount of resistance to solvents, oil, acids, as well as extreme temperature
  • These power cords do not tear or abrade easily
  • Retards flames easily
  • High resistance to the damage caused by sunlight and water
  • Great degree of flexibility and durability. The cords can be rolled into a neat bundle when not in use

If you are not sure whether the power cord that you have is EPDM insulated or not, you can actually test the insulator at home. All you have to do is heat a piece of the insulation in the Microwave for two minutes. If it does not emit any smoke or smell, then you can be sure that you have EPDM insulation on your portable power cord. This test would also prove the fact that the EPDM insulation can work on temperatures of up to 150°C.

If you need further information on EPDM insulation for portable power cords, or just need assistance from an expert technician about the product’s in-depth technical information, there are a lot of toll-free numbers on the internet that you can call. Most online stores do already list a few technical specifications based on the manufacturer’s information for almost every portable power cord that they sell, so there should be very little need for you to contact a specialist or personally go to a hardware store yourself.

Olflex SDP TC Severe Duty Power Cable

The Olflex® SDP TC Severe Duty Power cable, or simply SDP TC, is a Bus Drop approval cable that has some unique features that it has when compared to other Olflex® cables. One of those is the orange elastometric alloy jacket that covers the wiring. This elastometric alloy jacket is also TC-ER approved passing all UL standards that run for 600 volts. This means that you can apply this kind of cable for both commercial and industrial conditions, in cold and other hazardous environments, for control and/or power applications, and even for machine tools or in the electrical circuitry of factory installations. The heavy-duty wire, aside from being approved for 600 volts, is also approved for use in 1000 volts.

This cable goes has still more unique features compared to other motor supply cables. The finer stranding that it has gives it a little more edge. Its wire is also covered with pressure extruded jackets that make this cable a very flexible property for installation. The design of this wire also conforms to NOM and CE standards that make it a globally acceptable solution for wiring.

The construction of this wire is made of finely stranded tinned copper wires. These wires are then covered PVC or nylon insulations, which makes it a little different to other Olflex® cables which are covered with the special formulation of Lapp Surge Guard®. This, however, does not decrease the efficiency of this wire as it compensates with barrier tapes and a specially formulated elastometric alloy jacket.
This jacket makes this wire highly resistant against oil and other chemical intrusions that can cause damages or decrease in conductivity. Aside from the oil and chemical-resistant version, submersible pump approvals are also available in special orders. The Olflex® SDP TC Severe Duty Power cable is highly resistant against heat, though it could only burn or melt when exposed to extremely high temperatures. On the other hand, it is not very flexible so it is not really recommended for electrical machineries that require perpetual motion. However, this wire scores very high when it comes to toughness and mechanical rigidity.

The minimum bending radius for installing this wire is rated at 7.5 times the diameter of the cable. For example, if you have this wire in 26 awg, then you can multiply it by 7.5 to get the minimum bending radius for a 26 awg Olflex® SDP TC. This wire can work for temperatures as low as -40°C to even temperatures beyond 150°C. The nominal voltage that you can use this wire can be in 600-volts (based on UL-TC) or in 1000-volts (based on UL AWM), yet its test voltage can reach to even up to 4000 volts. Like other Olflex® cables, the Olflex® SDP TC Severe Duty Power cable can also be used for variable frequency drives of VFD’s. Yet at the same time, unlike other VFD cables, this one can also be used for non-linear power distortions that can be sometimes associated with other VFD’s.
