Product Description

High voltage vaccum circuit
Productin introduction
Vs1 type (ZN63) - 12 indoor vacuum circuit breaker is a indoor high voltage switch equipment, applicable to 12 kv rated voltage, three-phase power system frequency 50 hz, used as protection and control electric equipment, as a result of the vacuum arc extinguishing performance is good, anti-fouling ability strong, almost maintenance-free special superiority, especially suitable for high current load frequent operation.

Vacuum circuit breaker on outdoor high voltage column is a new type of outdoor high voltage switch equipment with rated voltage of 12KV, which is mainly used in distribution system of city network and rural network as load current, overload current and short circuit current. The external insulation is made of silicone rubber material, which has reliable insulation and strong anti-pollution ability.
