The brittle fracture of the mandrel during the operation of the composite insulator is generally considered to be caused by the poor sealing of the connection part of the mandrel a

Insulator manufacturers talk about the six main culprits causing insulator failures: 1. Lightning strike or failure caused by external force According to calculations, among the in

The main function of the insulator is to achieve electrical insulation and mechanical fixing, for which there are various requirements for electrical and mechanical properties. If

The broken string forms of composite post insulators can be divided into three categories: external tearing, brittle fracture and decay. Among them, there are few cases of external

The drop type fuse is an important component in the circuit system, which can protect the safety of the circuit and protect the electrical apparatus from abnormal voltage damage in

Drop type fuse is used to protect short circuit and overload circuit equipment. It is a kind of short circuit protection switch commonly used in 10KV distribution lines and distrib
