Conductive carbon black requirements for cable shielding.

Date:2024-06-11

Requirements for conductive carbon black used in shielding materials for cables, both internally and externally, include low electrical resistivity, high dispersibility, small particle size, large and rough specific surface area, high structure, and clean surface (low compound content).

Differentiation of conductive carbon black for internal and external shielding materials: The choice of conductive carbon black for internal and external shielding materials can vary based on the voltage rating (KV) of the cables being produced. For example, the specifications of conductive carbon black for internal and external shielding materials used in 10kV cables differ from those used in 110kV cables or 35kV cables.
