Overview
Description:

The arrester is the basis for the insulation coordination of various electrical equipment (transformers, reactors, capacitors, motors, motors, PTs, CTs, circuit breakers, contactors, etc.) of the power system. The protection performance of the arrester determines the internals of all electrical equipment of the power system. Insulation index (short-time power frequency withstand voltage, lightning impulse withstand voltage and operating impulse withstand voltage, etc.)

The product is fired by multi-metal oxide powder based on zinc oxide in the first year of operation. It has excellent nonlinear volt-ampere characteristics, fast steep slope response, large flow capacity, and self-blowing gap with gap product. Irradiation structure reduces the dispersion of discharge and has a small impact coefficient.

It is used to protect all kinds of electrical equipment, catenary and electric locomotive of electrified railway from damage of atmospheric over-voltage and operating voltage
