General

Normal multiple strand cable




There are different types of cable. The most common is multiple strand (more than 7 strands) of copper. There are also single strand cables and minimal strand (2-7 strands).
Cables have different areas and color codes.

Cable area
Specifications that give a cable area are always based on the area of the core (the copper strands). The cable area does not include the insulation.

Cable insulation (sheath)
Nearly all cables are of the insulated type and have either single or double insulation.
Some copper cables have no insulation.

Other types of cable





Shielded cables
Shielded cables are used for carrying signals from antenna and in wiring for engine control modules. Braided wire shield is wrapped around on or two conducting copper strands which provides protection against interference from electromagnetic high frequency fields.
Special tools are required for stripping, splicing and connecting shielded cables.





Twisted pair
Twisted pair cables reduce the effects of magnetically induced interference. When splicing twisted pair cables the splice points must not be made parallel.
