Multi-layer insulation constructions are used. With the high-voltage cable, three separate layers may cover the center conductor. The innermost layer will function as an electric screen, the intermediate layer is usually a PE insulation material, and the outer layer serves as an electric screen. The processing technique can be used for primary and secondary coating where the covering is on metallic conductors or coating previously insulated wires.

Electrical ( corona ) discharge treatment of polyethylene and polypropylene film has been used for many years in order to render these surfaces printable and suitable for lamination or coating. In this process the polymer film is passed over a grounded metal roller covered with a "dielectric" (insulating) material. Separated from the film by mm is an electrode bar to which a high voltage is applied (typically 15 kV at 20 K Hz). Air in the film-electrode gap is ionised, the corona discharge thus formed is stable and this "treats" the film surface. 

Uses of Chlorosulfonated Robber. CSM is used in applications similar to those of CM. It is used in automotive hoses, tubes, gaskets, electrical wire insulation (even in high-voltage power stations), industrial hoses, tank Unings, coated fabrics, conveyor belting, and other applications.
