Product description
GSC high/medium voltage SF6 load break switch, with a rated voltage of 12kv, 24kv or 36kv, can response and protect power system when there is an error. The switch can be either manual operation or electrical operation, and earthing function is optional. Switch fuse combination can protect the whole system. The rated current of fuse can be required in accordance with customer requirement. Compact size, easy installation and free of maintainence make the switch suitable for wide applications, especially for ring main unit. It also can work with vacuum circuit breaker to make a switchgear combination for excellent performance with favorable cost.
