Our Electrical Wire and Cable Website is Growing!

At WesBell Electronics we’re very excited to see the growth of our website in the tough 2011 economy. Our website offers electrical wire and cable for sale online and many more products that we offer that need to be ordered over the phone. It’s hard to keep updated pricing on copper wire because it changes every day. So we only keep our popular items available to buy as we work on procedures to get more items listed.

As more and more people visit our website we’re starting to see trends and percentages that are helping us move forward. If we get 1000 visitors we’ll see a certain amount of phone calls, orders placed online and orders placed over the phone. Based on that data, if visits increase 10 times then everything else should follow accordingly. That way we can put a budget on how much to spend to get our website to the next level.

Not only do we want to increase the visitors to our website, but we also want to increase the conversion rate to an order. So we started to offer free shipping on orders over $250 and exact cut lengths for electrical contractors and home owners who have no need for a 500 foot spool of copper wire. Like most sales people, we don’t like to say the word “no” to anyone that calls and needs a somthing specific so work as hard as we can to avoid it.

Our web design team has been working hard on the layout of our website to make it much easier to navigate for those who have a tough time using the internet and computers in general. We use the keywords that we promote so that it’s easy, once you arrive, to find what you’re looking for.

We have many pages on our website that reference welding cable and strongly promote it throughout the search engines. That puts us near the top of a search when someone types in the phrase “Welding Cable”. We aren’t going to change the term welding cable to the manufactures part number once you get to our website because we know it would be difficult for you to find.  

We appreciate any feedback you might have on our website or our products because we’ll use that information to figure out how to make your experience better. As an ISO 9001 certified company we must follow strict procedures to comply with the their standards. It assures our customers that we handle things the right way and take the neccessary steps to fix something that might go wrong. Not only do we want to avoid a similar mistake, but need to take action in order to be compliant with the ISO standards.

Welding Cable AMPS and Pricing

Welding cable comes in different gauge sizes which allow a certain amount of AMPS to carry on to the application. That means you’ll have to figure out which size of cable you’ll need in order to be sure your welder has enough AMPS in run. Buying a larger size will work but you’ll pay more money and there aren’t too many people that want to do that.

Your best plan will be to call a certified electrician to help you figure out the awg size you need based on the size of the welder and the length of cable you plan on having. There’s a calculation done that meets the standards of the NEC (National Electric Code) in order to be sure you have enough power and that your up to date with the town or state codes.

Welding cable starts as small as 6 awg and gets as large as 500 mcm. It’s manufactured with thin copper strands and a rubber insulation to increase the flexibility. The only difference between the 4 awg and the 2 awg is that the 2 awg will have more of the copper strands to make a larger awg and carry more power to the welder. They’re all very flexible cables so there’s no need to worry about a stiff cable around the shop during warm or cold weather.

THHN electrical wire is a similar type of single conductor copper cable but it comes much less flexible. Usually people who use welding cable wonder why anyone would want a wire as stiff as THHN wire. The stiffness helps keep the electrical wire straight when going through conduit. A welding cable would get bunched up as it’s being pushed through so a flexible cable is actually less helpful even though it’s more expensive.

Each larger gauge size will be slightly more expensive which means you want just enough to cover the amount of AMPS traveling throughout the cable so you don’t over spend. Talking to a certified electrician will tell you exact size you need to buy which means you can call a distributor with detailed information.

If you look on our website for pricing on welding cable you’ll see how expensive the larger cables actually get. The 6 awg goes for less than $1.00 per foot in the end of 2011 but the 500 mcm cable goes for about $16 per foot with 9 more choices in between.

We also offer an Super Vu Tron welding cable that comes in orange insulation only. It has 34 awg copper strands instead of 30 awg strands which makes it much more flexible. It’s also manufactured with a much stronger, more durable, insulation for outdoor protection. It’s most commonly used for industrial applications requiring use outdoors where the cable will be stepped on, run over by vehicles or dragged across the concrete where a standard welding cable insulation might get punctured.

Please call us if you’re looking for welding cable, electrical wire or even heat shrink tubing as we have been in business for over 20 years as a wire, cable and tubing distributor.

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.

            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.

            Romex® Wire- The Standard Wire for Homes

            Romex® wire has become really famous due to its time saving quality. It runs behind walls and connects appliances to their respective switches. This cable comes in a variety of sizes depending upon the amount of power required for a particular appliance.

            Romex® 12/2 and Romex® 14/2 are two most popular sizes for homes. Though this wire is very popular in home wiring system, it cannot be taken outside, as the moisture will eat through its cladding and insulation.

            Though Romex® wire is meant for indoor use, sometimes you need to take a part outside as well. In such a case, it’s better that you use UFB cable. It is an underground wire, which does not require conduit. This cable can easily be used outside, and underground too.

            If you do not have any electrical experience, make sure you leave the electrical work to the experts. There’s no need to work on it if you don’t know anything about electricity. This kind of work is dangerous and can pose a danger to your life. If you have decided to do it on your own, make sure you turn off the power supply and wear rubber gloves.

            If you want to connect small power sources to big power sources inside your home, then Romex® 8/3 and Romex® 6/3 cables can be used. But then again, there is the same problem- Romex® NMB Cables cannot be taken outside. If your electrical wiring must go outdoors, you should use UFB cable. The expense isn’t that much higher.

            In case you want to do electrical fitting for your garage or barn, then a small UFB cable would be sufficient. You can go for UFB 6/3 or smaller if you want. But make sure you do not use Romex® wire for your garage, because this wire will wear out fast and lose its insulation really soon.

            These are just some standard sizes. The ideal cable size would depend upon your house and application area. It is better to talk to an electrician and determine the cable that would best suit your needs.

            Learn More about the Common Electrical Wire

            Electrical wiring work can be risky. If you need to do some work related to electrical wire, then you must have experience and knowledge about how electrical things work. When it comes to working with electricity, you cannot work on the trial and error procedure. Electrical mistakes are deadly and can even cause loss of life. This is why, when you work with electrical wire, you must be clear about certain things. There are a few situations to help you with your electrical problems.

            First of all, let us talk about wiring a switch.

            Using a home switch is very easy, but wiring may take a bit of knowledge. If you are going to wire an on-off switch, then it is a very simple task. There are three types of wires in a switch- green, white and black. Divide the black wire in 2 parts, and connect each part on terminal screw- on top and bottom. Connect the white wire with the light colored terminal and the green wire to the ground screw. Once this is done, your switch will be ready to work without any problems. In case you think that you cannot do this properly, it is better that you take help from an experienced person.

            Let us now discuss how to wire a fan, specifically- a ceiling fan.

            Wiring a ceiling fan is not very difficult, but if you do not have any electrical experience, it would be better if you call an expert. You may use a single switch to operate the ceiling fan for the sake of simplicity. Simply connect the black wire of the switch to the black wire of the fan. In case you want to wire a light as well, then you can connect the black wire of the switch to the blue wire, as well as the black fan wire.

            Using a common electrical wire is very easy if you have the proper knowledge and tools. When you work with electricity, make sure you switch off the main power, and keep yourself insulated by wearing rubber gloves. Never work with electricity if your hands are wet.
