Product Description
1. LW36 Type Live Tank 145kv 1250A 2500A 3150A Sf6 Gas Circuit Breaker
145kV SF6 circuit breaker adopts three phase porcelain knob construction, outdoor design.
Three phase serve for one spring operation mechanism, locates in the middle, three phase ganged. It adopts SF6 gas as insulation and arcing medium, the SF6 gas should be connective in three poles at working, it adopts
pointer density relay to monitor pressure and density. Improve mechanical efficiency and Reduce operate power by the greatest extent, because of adopting auto-accumulation energy principle and making use of optimal
design.
