LW17-35KV
LW16-40.5 is an outdoor three-phase AC high voltage SF6 circuit breaker designed for 40.5kV (35kV class) power transmission and distribution systems. It uses SF6 gas as insulation and arc extinguishing medium, equipped with spring operating mechanism, and meets IEC and GB standards.
This product is mainly used in power substations, industrial and mining enterprises, power plants and distribution networks to control and protect circuits. It can reliably switch rated load current and short-circuit current, with stable performance, long service life, low gas leakage rate and easy maintenance.
It is suitable for outdoor environments and can be widely used in power grid transformation, new construction and renovation projects of 35kV / 40.5kV power systems.
