Arrester disconnect is a device for disconnecting an a rrester from the system in the event of arrester failure, to prevent a persistent fault on the system and to give visible indication of the failed arrester,TL-1 is a thermal explode disconnector, our products as per IEC60099-4 Standard.

Zinc-oxide varistor
RU is specialized in producing ZnO Varistors for surge arrester ranged from Dia 32 —Dia 82mm with alternative height, which is suitable for all kinds of 5kA and 10k surge arrester.Our MOV blocks can withstand high current impulse 65kA and 100k and other excellent performance.
Surge arrester monitor & discharge counter
Discharge counter is used for recording the discharge times of surge arrester in operation.Monitor is connected in series with surge arrester and operates in power system.lt measures on-line real-time leakage current of surge arresters and records the monitor discharging times. It is used for all kinds of metal oxide surge arrester in the voltage of 220KV and below, the service condition is the same with the surge arrester connected.
