Why Choose Copper Wire?
Only silver has a higher conductivity rating than copper, but it is considered a precious metal. Copper, being a non-precious metal, still provides high conductivity at a much lower price.
Aluminum wire is also frequently used a conductor, but it has a lower conductivity than copper, making it, for the most part, less efficient. Aluminum wire has to have a cross section 1.6 times larger than an equivalent copper wire in order to create the same current capability as an equivalent copper wire. This also makes copper wire less cumbersome and bulky than aluminum wire.
Another advantage that copper has over aluminum is its ability to survive extreme conditions since it is 300% more durable.
Copper Wire Specifications
Copper wire weight is affected by insulation build.
The insulation can be either be plastic, rubber or, in the case of magnet wire, a thin varnish or a yarn.
Insulation is meant to protect bare copper wire from coming in contact with itself while it is being wound. The turns of bare wires, which are not insulated, would short out if they were to come in contact with one another. Insulation acts as a buffer between the turns and is necessary for wires that are wound hundreds, possibly thousands, of times.
The measurement of the insulation is known as the build. Subtract the diameter of the bare wire from the total diameter of the insulated wire and this will give you the measurement of the build.
Single, heavy, triple or quadruple builds are available. Single and heavy are the most common, and they will have a slight effect on copper wire weight.
Copper Wire Weight
Standardized specification for solid, round wire are based on American wire gauge (AWG), which is used mainly in the United States and Canada. The wire gauge will provide characteristics for the wire, including the diameter, current and weight. Standard AWG numbers start at 0000 and end at 40. Wires with a gauge higher than 40 will be so small they will have theoretical diameters.
Wire is calculated by weight, rather than length, simply for accuracy. Calculating copper wire weight is a quicker and simpler process than measuring miles of wire.
Copper wire weight decreases as the wire gauge goes up. A 0000 gauge wire will weigh 640.5005 lbs per 1000 feet, while a 40 gauge wire weights 0.0299 lbs per 1000 feet.

"I needed a 3 phase rotary phase converter to run a DoAll Mill."
The family friend I purchased the mill from had purchased one from TEMCo several years ago, and told me that's the company to deal with. Very competitive price, fast delivery, and a solid, quality product. The shipping was fast, and the phase converter was crated very well and had zero damage from shipping. This thing runs so quietly I hardly know it's running.
I HIGHLY recommend TEMCo!

"Excellent advice, service & product".
The staff helped determine exactly the size converter I needed, answered any questions I had thoroughly. The unit was shipped quickly & was very welled packed. The product is so well designed that installation was a breeze & the converter works great.
Got me up and running very quickly.

"The service was awesome."
I had many tech question and they spend about 30 mins on the phone answering all ofthem for me. It is not to often to find service like that!!!!! I am so happy and will definitly purchase from them again. A+++++

"Perfect FAST transaction..."
They delivered the 5-HP Electric Motor IMMEDIATELY in Perfect Condition. They bent over backwards to enable us to execute payment using an alternative method, Thank You So Much. We are comming back soon for a Power Converter. ! ! !

"You guys were referred by our electrician as well as our local light/electric company."
Very friendly, very knowledgable.
- Low Country Recyclers LLC, 9/08/11
"Have ordered transformers from this company previously and just ordered again."
Quick order shipment and prompt customer service. When they accidentally sent the wrong transformer on one order they immediately sent a replacement without any hassle at all! Good to do business with.
