Product Description

Application Scope

It is used for all kinds of metal oxide surge arrester in the voltage of 220kV and below, the service conditions is the same with the surge arrester connected.

Arrester Disconnector

Arrester disconnect is a device for disconnecting an arrester 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. The products are as per IEC60099-4 standard.

Note: 1. each kind of chinese standard model can be derived from several type of products, limited the space, so we don't list them one by one. You can contact with our technical department if have the problem.
2. a. "nominal voltage system" of date, for the column of lighting protection of motor rated voltage motor. b. "power frequency nominal voltage" of date, for the column of high voltage over 110kV arresters effective voltage tolerance. c. "impact of discharging voltage" of data. for 110kV above 50% lightning shack pressure arrester discharge voltage.
3. due to the purpose and the voltage level more, not specified name arrester 30/60 operation residual pressure corresponding impact the impact of the current result in accordance with the relevant standards to select.
4. most products can match counter and disconnector etc. knits match the counter should add "J", matche the disconnector should add "L".
5. If it's the porcelain arrester, without "H".
