How to distinguish conductive carbon black for internal and external shielding materials

 

Conductive carbon black for internal and external shielding materials can be selected according to the cable KV produced. Different carbon black products, such as internal and external shielding materials for 10kv cables, internal and external shielding materials for 110kv cables, and internal and external shielding for 35kv cables There is a certain difference in the product's conductive carbon black product index.
