42kV lightning arrester Surge arrester with polymer housing for electric railway

surge arrester manufacturer and supplier, lightning arrester factory

Surge arrester selection guide here is for the polymer housing surge arrester in the electric railway system. We manufactured MOA since 1990, and we also make the MOV by ourselves.

There are two types of housing for surge arresters. Silicone polymer housing or composite metal oxide surge arrester and porcelain housing metal oxide surge arresters. Surge arrester rating calculation is a guide for selection. Both types of surge arresters are the key equipment in the electric power system. They are protecting the equipment from the lightning impulse and overvoltage impulse.

Rich Power Company offers a complete range of surge arresters for high and medium voltage applications. The range comprises of AC and DC solutions up to 1,100kV and arresters for special applications like railways, DC-voltage limiting devices and many other purposes. The designs comply with the IEC 60099-4 and ANSI/IEEEC62.11.

The following type of surge arrester is used in the electric railway system protecting electric system, overhead line net, Motor against atmospheric overvoltage impulse and operation overvoltage impulse.
