GW Series HV Disconnector

GW series model outdoor HV AC disconnectors are used in HV lines from 72.5 to 145kV power systems, in the case of no-load current to switch lines and to carry out electrical isolation in order to repair HV busbars, circuit breakers, other electrical equipment and charged HV lines.
This series of disconnectors can be equipped with CJ6B electric operating mechanism or CS17 or CS9 manual operating mechanism.
The disconnector is manufactured under the IEC 62271-102 standard.
