Product Description
Outdoor High Voltage 33Kv Outdoor Vacuum Circuit Breaker Auto Recloser
Quick Detail:
Technical Parameter
The ZW20-12 Outdoor Vaccum Circuit Breaker with SF6 Gas Insulation, is outdoor high voltage switch
equipment with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing
load current, overload current and short-circuit current of the power system. The circuit breaker is suitable
for application as protection and control in transformer stations, industrial and mining enterprise as well as
the urban and rural distribution networks, and it is particularly suitable for places with frequent operations
and automated distribution networks in urban networks. The product is matched with the controller to meet
the requirement of a distribution automation system and it can be used for reliably and effectively finishing
functions of the traditional auto recloser. The circuit breaker adopts mature case type sealing structure, the
inside is filled with SF6 Gas, so it has excellent sealing performance so as not to be affected by external
environment and it is a maintenance-free product. The spring operating mechanism adopts straight chain
main transmission and a multi-stage tripping system, the reliability of actions is high, and it is an excellent
product of on-pole circuit breaker.
