The most important and the most insulation used in cable construction is P.V.C. Polyvinyl Chloride) which is called far beam or plastic. P.V.C is a non-flammable insulation and this is a good advantage in cables. It has a lot of flexibility. Things like the cheapness of mass production and the simplicity of manufacturing have caused more than 90% of low pressure cables to be made of this insulation. Another type of insulation called PET (polyethylene) is used for wires and cables, which is fireproof and is used in special places. In some cables, rubber insulation is used, which is not very useful.
Cable conductors are made of copper or aluminum. If we want to use a cable with an aluminum conductor for aerial cabling, one strand must be steel.
