Cutting and Stripping PVC Hook Up Wire

WesBell Electronics is an ISO 9001 certified distributor for wire and cable along with a value added services department of cutting, stripping and assembling lead wires. Being ISO certified means that we document all of our errors in house, analyze them and find ways to continuously improve our procedures.

Kenneth Bell started the company over 20 years ago selling bulk wire and cable. Anything from hook up wire to shielded and unshielded electronic cables. Just like many businesses that grow over the years we started getting inquiries to cut wire and cable to length which lead us into our value added services department.

Once we started cutting and stripping hook up wire we began making small wire harnesses and cable assemblies a short time later. It can be very hard to decline business so we accepted it and performed 100% quality checks to be sure the product matched what the customer was looking to receive.

Over 15 years later we’ve improved our process ten fold with a quality initiative of 0% defective product. While that can be very difficult to achieve with human error possibilities we strive to get closer and closer to that goal every day.

We’re currently located in Merrimack NH and perform kan ban systems in surrounding areas of Manchester, Nashua, Keene, Concord and Portsmouth New Hampshire. A kan ban system is an order for 1000 pieces that require 200 pieces to sit on the shelf ready for immediate delivery by our personnel or via UPS. Once the 200 pieces are delivered another 200 pieces go directly into production and move to the shelf when completed.

Even though we do perform value added services we stand by our niche of electrical wire and cable distribution throughout the USA. We purchase electrical wire, electronic cables, portable cord, hook up wire, PTFE wire and cable and heat shrink tubing from over 50 different manufacturers.

With a number of choices that are being offered, coming up with the best decision is definitely going to be an overwhelming one. The number one tip that you should remember when shopping online is to be properly equipped with the right knowledge. Moreover, you should also determine the background information regarding the products that you have in mind.

Product review pages will be of great help in your search. If you have a technical expertise regarding the right way of installing the cables, then all you have to do is to find the most appropriate electrical wire. There are four vital points for you to consider before placing an order for your electronic cables: shielding performance which would also include the type of cable jacket that are available, flexible characteristic of the wires, resistance to various chemicals especially water and corrosive substances and the range of temperature that the item is cable to handle.

The best thing about reading the product reviews page is that you are given the assurance that the product that you are going to purchase will be able to properly handle the pressure especially if you will be using several home equipments that requires higher voltage.

Shielded Plenum Fire Alarm Cables

Shielded plenum fire alarm cables are engineered to be used in a buildings plenum to lower the chances of a fire spreading throughout your home. They’re manufactured with a flame retardant coating such as PTFE to help cut back on the cable’s production of smoke and harmful gasses should it begin to burn. These types of cables are the ones inspectors like to see when checking a building for the best fire protection.

Fire alarm cable is used in applications when hooking up smoke detectors, signaling, fire alarm, and fire protective circuits becuase they have all been known to need the extra fire protection to continue working when a fire erupts.

EMI is electromagnetic interface which is something that an insulation cannot block a cable from. It’s “electrically noisy” and disruptive to other equipment around it which an aluminum polyester shield can block. Many fire alarm cable installations and PTFE cable installations require a strong shield in order to keep all of the equipment running smoothly.

A cable is transferring EMI to another source and the best way to block that is through the use of a shield. The shield surrounds the copper conductors which blocks any interference coming in and blocks anything going out so that all of the cables near each other can effectively do what they were set up to do.

As you can see there’s quite a bit of engineering involved in each type of fire alarm cable. If manufactured wrong or poorly they can spread a fire much faster than expected throughout the home or building. The shield could also cause problems with the EMI so it’s important to make sure the cable that you buy has all of the specifciations you need for your application.

Please call you have any questions about our shielded plenum fire alarm cable or anything else regarding the items on our website.

Electronic Wire and Cable Section by Manufacturer

We added an electronic wire and cable section to our website geared toward selling our Alpha Wire manufacturer line. They offer many communication cables, shielded and unshielded, with superior protection to standard electronic cables.

Alpha has always taken extra pride in the cables they manufacture because they want their cables to out last each and every similar cable on the market. Instead of just making a PVC jacket like every other manufacturer Alpha Wire makes a premium grade PVC jacket that has UL and CSA approvals for higher and lower temperature ratings.

Alpha Wire has their own brand of electronic cables called XTRA Guard®. Their are six different types of XTRA Guard cables that include shielded, unshielded, PVC, PTFE and flexible. They even have different temperature ranges that reach higher and lower temperatures than the standard cables of its class.

Each XTRA Guard® type has a 300 volt and 600 volt cable that can be shielded or unshielded. They each range from 24 awg to 14 or 16 awg with as many conductors as 70 and as many pairs as 77, so there’s a wide range of applications these cables can be used in. Some of those applications include high technology applications in controlled environments, medical electronics, point of sale equipment, computer peripherals and industrial process controls.

The XTRA Guard 1® material has an unsurpassed flame and moisture resistance, fast and easy stripping of the insulation and jacket, UL and CSA recognition and flexible cable routing requirements. The conductors are manufactured with tinned copper strands and a color coded premium grade PVC insulation. It has passed the VW-1 flame test and CSA FT4 flame test to meet any approvals needed for the application of this cable.

I encourage you to compare the specification sheet of an Alpha cable to another manufacture’s identical cable to see the differences in temperature, flexibility and durability. Alpha makes cables with a longer life than any other cable because they want to keep a good name for themselves so that anyone looking for a superior cable will call them.

We plan on adding many more Alpha Wire products to our website for our customers to find. We’d like to maintain a good reputation for ourselves as well so selling an Alpha product will help our customers know how serious we are about the actual application rather than just the sale of any standard product.

Information and Facts on Power Cable

Power cable comes in a variety of shapes and sizes, and can look complicated to the layman. These cables can be single-conductor, multi-conductor, as well as industrial strength or for personal use. Each type of power cable has its own advantages, which make them suitable for certain types of applications.

A power cable is categorized in three classes, 1) high voltage (for applications requiring load greater than 40,000V), 2) medium voltage (for applications requiring load between 6000V and 36,000V) and 3) low voltage (for applications requiring load below 1000V). These cables are used for feeders and other heavy machinery, along with branch circuits in electrical utility, commercial and industrial applications.

Single-conductor power cable is used in various applications such as stage lighting, locomotives, DLO and for welding purposes. Each single-conductor cable, depending upon its use, has a different rating for amps, voltage, flexibility and insulation, each having a different price-level.  

There are many multi-conductor cables; extensions cords, Type G-GC, Type W, SOOW and portable cords, each encased a rubber jacket for insulation. These cables are safe and flexible and when additional flexibility is required, there is a multi-conductor cable available for this need. The SOOW multi-conductor cable is similar to the extension cord (before the plugs are attached) and is generally used to supply power generators and tools in industries.

The least-expensive power cable of this group is the welding cable. Welding cable has a rubber jacket and flexible copper fibers and is rated to 600V. DLO cable also has the rubber jacket, is rated to 2000V and has tinned copper fibers. The DLO can carry more power and therefore has a higher corresponding price.

Remember, when installing power cable, it is recommended that you consult with your electrician. And when it is time to purchase your cable, some helpful hints include knowing the operating temperature, amperage, voltage, outer diameter (cable diameter + insulation jacket). Please call WesBell at 800-334-8400 for all your cable needs.

Installing THHN cable in cold weather

When the weather is cold, you can have problems not just with your heating bills and skin, but also with your cables. For example, the THHN cable is easily vulnerable to deterioration due to cold weather.

THHN cable is Thermoplastic, High-Heat Resistance, Nylon-Coated, therefore the name- THHN. Though it is versatile cable and does not fall under any specific application category, it is mostly used under Hook-up wire class.

Strengths

THHN cable comes in a variety of strengths. And since it is made from thermoplastic material, it is easy to heat and cool this wire many times to change its shape. But there is a limit to the number of times this wire can stand heating and cooling. It has its lower and higher temperature limits and if the temperature changes cross this range, this wire can become unstable. Temperature range depends upon manufacturers.

When the THHN cable comes with ‘High Heat’ rating, it means that this wire can be used in high temperature scenarios. These wires come with various specifications, which determine the specific applications where these can be used. For example, “Nylon coated” means that a certain thermoplastic material is used in this wire.

Coming to installation of the THHN cable in the cold weather, there are some simple guidelines that you should follow. Keep this cable indoors, and not in the outdoor harsh environment. Generally, a temperature of 65°F works well.

If keeping the cable indoors is not possible, bring it inside for at least 24 hours, before you install it.

If the outside temperature is below 14°F, then do not install the THHN cable.

While installing the cable, take care that it is not dropped on the floor, as these impacts can cause cracks in the stiff cable material.

Make sure you do not bend the cable too much, because it can cause the cold and stiff cable to break.

            Once you have installed it, this cable will work properly in environments with temperature higher than 14°F.

            All you need to Know about High Voltage Cable

            If you want to transfer large amount of electricity, then high voltage cables are your safest bet. There are various forms of these cables, and all are used for different purposes depending upon voltage of electricity and the machines for which these are used. Three types of cables are: high, medium, and low voltage cables. Out of these, high voltage cables are used when the voltage is above 1000 V. These cables are heavily insulated to prevent any risks or hazards.

            • AC power cables

            These cables are used to transfer up to 2000 V of electricity. The composition of these cables includes cross section of cable, polyethylene insulation, and conductive material like aluminum or copper. These cables are highly flexible and work well both in low as well as high temperatures. The cable layers are fused together to avoid air seeping in, as this can cause electrical discharge, thereby damaging the insulation.

            • HVDC cables

            These are specialized cables that are designed for high voltage direct currents, and thus are called HVDC cables. If you have seen a power line, then it would be easy to understand, as a power line is also an HVDC cable. These cables are helpful in carrying large loads of electricity over longer distances. After reaching the transformer, their electricity is converted to AC form. Thereon it runs with lower voltage, and is transferred to businesses and homes.

            • X-ray cables

            These cables are used to link other high voltage cables with X ray machines. These are also used to connect high voltage cables to other scientific equipment that require higher loads of electricity. These are highly flexible cables. They have a braided cover of copper wires, and are insulated with rubber. These are fused to high voltage cable to provide safety, and to reduce the hazards of electric shocks.

            All these cables are not for home use. These are used to connect high power sources to other devices or cables. If you want to buy these cables, make sure you go for the best quality, as bad cables can lead to dangerous situations.

            Using PTFE wire for High Temperatures

            Wire insulated with PTFE, or PTFE wire, is very useful. If you have been using PVC hook up wire to fight insulation melt downs, then you will be pleased to use PTFE. It cannot even get affected by a soldering iron. It has been used since the 1960’s due to its excellent performance in high temperature scenarios. Some companies also use it in classification of surface electronics.

            PTFE wire has got copper strands, plated with sliver. The silver plating, along with PTFE insulation helps the wire to sustain extremely high temperatures. It is much better than basic hook up wire that suffers from melt downs in high temperatures. And due to its great heat withstanding ability, PTFE wire comes expensive. But in case your needs are about wiring places with extremely high temperatures, it will be a good investment in the long run.

            This wire is made by following many methods. Two of the more common methods are wrapping and extrusion. Extrusion is the most common one and is done usually in the standard sizes of 24 AWG and 22 AWG. There are also some smaller sizes, where space is an important factor. The covering comes in fused and wrapped types. PTFE is also used as the outer jacket of co-axial cables.

            PTFE wires also have great resistance to moisture, flame, damage from soldering iron, and thermal aging. Apart from that, the PTFE (polytetrafluoroethylene) coating is able to resist many harsh chemicals, ozone, greases, and solvents.

            You can install these wires at many places, as they are very easy to fix. It also has low degree of power loss, and thus is great for high frequency usage. Because these wires are small and slippery, they can be used almost anywhere.

            PTFE or Extruded PTFE hook up wire has 3 types: Type E (most commonly used, and rated for 600 V), Type EE (having thicker PTFE jacket, and rated for 1000 V), and Type ET (having thin cover, and rated for 250 V). All 3 of them can be used for temperatures up to 200o C

            Basics of Bare Copper Wire

            We all know that of all the metals used all around the planet, copper is the number one metal in terms of its usage. This is because it is the most versatile metal, and it touches the lives of people in one way or the other. It has a significant role to play in electrical engineering branch in various ways. It has great conductivity power, and thus is used a lot in making electrical wire. Although there are many other available metals as well, but none can beat the versatility of copper.

            Copper wire is available in both forms- with and without insulation. It depends upon the engineers- whether they want insulation or not. Depending upon where they are using the wire, they decide if it should have insulation or not. Both insulated and bare copper wires are used in different applications. They have their use in different engineering segments.

            The bare copper wire is also called ground wire, since it has no protection or insulation. This wire is generally used as the platform for various wires and cables.

            This wire can come either in solid form, or in small AWG sizes, wrapped to make some specific gauge. Experts say that using small AWG sized wire allows more flexibility to the wire, and it bends easily around the corners. Although flexibility is a good thing, but not in all cases, so a solid form bare copper wire is preferred in many scenarios. For example, electrical contractors require stiff wires, so that the wire could be sent through a conduit for longer distances.

            Green THHN wire is called ground wire, particularly when that wire has to be used outdoors. It is used for grounding purposes to safeguard people against hazards.

            So this is where bare copper wire is used. But before you purchase this wire, you must make sure that the company you are buying it from is a good and trusted one. One simple solution is to look for this wire online. You can find many trusted online companies that can provide you the kind of bare copper wire you want.

            Types of Insulation- Hook Up Wire

            If you are using PVC hook up wire for electrical purposes, you should know about the insulation that you can use with this wire.

            UL 1007

            This wire is a form of hook up wire, which is particularly used for 300 V PVC cable that runs at about 0.016 inches of thickness of the insulation material. The popularity of the term UL grew a lot because the UL confirms that a wire can withstand the voltage and temperature that it claims to handle. Therefore, UL 1007 cable is endorsed by UL to work at 300 V, as it is mentioned on its specification sheet.

            UL 1061

            UL 1061 is another PVC hook up wire that is quite similar to UL 1007. It has 0.009 inches of thickness of insulation material. Like UL 1007, it also supports 300 V. It is generally used with the appliances that need an outlet with smaller diameter.

            UL 1015

            Yet another PVC hook up wire, the UL 1015 supports 600 V, as opposed to 300 V supported by UL 1007 and UL 1061. Since it supports higher voltage, it needs thicker insulation. The thickness of insulation material for this cable is 0.032 inches. The range of this wire is from 10 awg to 24 awg- but before the UL type could change.

            PTFE

            PTFE is another type of hook up wire. It supports insulation at high temperatures going up to 200 degree Celsius. Other PVC insulations work up to temperatures of 105 degree Celsius. Apart from the temperature difference, PTFE has copper plated with silver, and not tinned copper. This feature also helps it to sustain high temperatures.

            These wires were some of the hook up wires that you could use while working on an electric application. Some of these cables cannot stand too much wear and tear, and so they are more suited for indoor works, while some cables are rough and tough, and so can be used outdoors as well as underground. Before you buy any type of wire, you must consult your electrician and take his opinion.
