Description
ZW20-12F outdoor column high voltage vacuum circuit breaker, used for outdoor high volt. Distribution Switchgear, rated voltage 12kV, three-phase AC 50 HZ. Mainly used for opening, closing the power system load current, overload current and short circuit current. The main configuration consists of vacuum breaker, CH-40 controller, external voltage transformer (Note: distribution automation line ring network available in bilateral PT) three parts.
This product are widely used in 10kV, 13kV city, rural power grid space ring network for disconnecting switch, contact switch, automatic switch device which can implement the ring deployment line load.
It uses vacuum arcing SF6, N2 mixed gas as dielectric, to introduce the Toshiba VSP5 gas seal, explosion, insulation structure technology, the overall excellent sealing performance. Inside is filled with SF6, N2 mixed gas which does not leak, not affected by the external environment. The spring operating mechanism with miniaturization and performance optimization design, action reliability is much higher than the traditional spring mechanism
