Product Detail
Product Overview
ZW20-12F/T port-port series outdoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is outdoor power distribution equipment with rated voltage of 12kV and three-phase AC of 50Hz.
Product Features
The box adopts VSP5 gas sealing, explosion-proof and green-proof structure technology, and the inlet and outlet conduits have also improved their sealing performance. The overall sealing performance is excellent, and the SF6 gas filled inside does not leak and is not affected by the boundary environment. Its spring operating mechanism has been miniaturized and optimized for reliability and stability. It adopts direct chain main drive and multi-stage tripping system, action reliability and stability than the domestic traditional spring operating mechanism to improve several times; the main circuit of the shaft and the sleeve of the contact between the use of the internal external tensioning bracelet structure, the main circuit of the contact resistance is small, low temperature rise. Therefore, the ZW20-12F type outdoor column vacuum circuit breaker is a maintenance-free product.
