LW3-12 12kV Outdoor SF6 Gas Circuit Breaker is a widely used pole-mounted high voltage switchgear for 12kV outdoor power distribution network. It uses SF6 gas for insulation and arc extinction, featuring compact size, light weight, maintenance-free and stable performance. Perfect for overhead line sectional control, loop switching and overload & short circuit protection.
LW3-12 I II III type outdoor SF6 circuit breaker is a new type outdoor high voltage electrical equipment which takes SF6 gas as its arc extinguishing and insulation medium. There are three types of operating mechanism-I type manual energy storage spring operating mechanism, II type motor energy storage spring operating mechanism and III type DC electromagnetic operating mechanism.
Compared with other 12kV outdoor circuit breaker, LW3-12 outdoor SF6 circuit breaker is simple in
estructura con buenas prestaciones de extinción de arcos y aislamiento.
With LW3-12 SF6 circuit breaker, users can reduce cost, eliminate danger of fire and improve the reliability of electric system.
