Scope

This document specifies the name code and product presentation method, technical requirements, test methods, inspection rules, packaging, marking, transportation, and storage requirements for semiconductive shielding materials (referred to as "semiconductive shielding materials") used in cross-linked polyethylene insulated power cables with a rated voltage of 66 kV to 500 kV.
This document applies to cross-linked semiconductive shielding materials made from polyolefin resin as the base material, with the addition of conductive carbon black, peroxide crosslinking agents, and other additives, and then processed by melt plasticization and granulation.
