The arrester is an over-voltage protector. It is mainly used to protect various electrical equipment such as transformers, switches, capacitors, wave blocks, transformers, generators, power cables, etc. in power systems, railway electrification systems, and communication systems. Damage to atmospheric overvoltage, operating overvoltage and power frequency transient overvoltage is the basis for insulation coordination of power systems.

Composite outer casing metal oxide arrester adopts integral molding and two-head encapsulation process, with good sealing performance, excellent explosion-proof performance, pollution-free cleaning and cleaning, and can reduce fogging and wet flashing, corrosion resistance, anti-aging, small size and light weight. It is easy to install and maintain. It is a new generation of porcelain sleeve arrester.
