Application

Surge Arresters For Medium Voltage Systems


Our Metal-oxide Surge Arresters for use in metal-encapsulated switchgear as well as for use in distribution networks for the protection of overhead lines, cables, stations, transformers, generators, capacitors and for the protection of motors and components of power electronics and secondary equipment.

The surge arresters limit harmful over voltages, which are generated in the network by lightning strikes or switching actions thus improving the availability of the power supply. The surge arresters full fill special high requirements regarding ambient conditions, energy handling capability, protection level and stability in service.
