Product

ZN28-12 series vacuum circuit breaker is a high-voltage indoor switchgear with rated voltage of 12KV and three-phase AC 50Hz. The product conforms to the GB1984-89 standard, and the overall structure of the product is the integrated installation of the switch body and the operating mechanism, the integrated installation of the switch body and the lifting, and the separation installation of the switch body and the operating mechanism. The one-piece structure is the basic type of ZN28-12. The split structure is ZN28A-12 type, which is suitable for various fixed switchgears, such as GG-1A(Z)XGN2A10(Z), etc. The product can be equipped with CD17, CD10AA DC electromagnetic operating mechanism and CT17, CT19 spring energy storage operating mechanism.

ZN85-40.5 series indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is suitable for three-phase AC 50Hz, rated voltage 40.5kV power system, can be used by industrial and mining enterprises, power plants and substations as a load current, overload current, fault current. The circuit breaker and the operating mechanism adopt the upper and lower arrangement structure, which effectively reduces the depth of the circuit breaker.

ZN85C-40.5/T2000-31.5 indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is suitable for three-phase AC 50Hz, rated voltage 40.5KV power party organizations at all levels, can be used for industrial and mining enterprises, power plants and substations as a load current, overload current, fault current.
