Among all kinds of cable, the insulated cable is a type that comprises of two or more intertwined metal wire conductors. It can be insulated into different types, such as PVC, Teflon, ceramic or glass. The most common one is PVC insulating because of the moderate low or high temperature. And the fiber woven glass insulation can bear maximum heat to 1,300 Fahrenheit. Except for these non-conduct materials, there are also some metal materials for insulation.
Copper, the most common metal material for insulated cable, is applied because of its specification of easy bending, stretching, shaping and manipulating without any damages to the wire. Most importantly, copper is well known for its corrosion resistance. In addition, places in highly moisture and humidity are commonly used the copper insulated cable for high voltage application. Besides, the aluminum is also a common material for insulation. They are nor able to load high voltage as copper; however, the lightweight and low cost make the aluminum insulated cable more ideal for the use of lengthy run application. Last but not the least, is a combination of these two materials, making the insulated cable an ideal one for communication cable. The copper clad aluminum wire (CCAW), an aluminum wire coated with copper, is lighter than copper wire. This cable wire can boast a higher electrical transmission frequency than either copper or aluminum type. Most common way of application of CCAW is television connections, cable modems and Internet connection cables.
