LW33-126KV
LW33-126kV is an outdoor three-phase AC high voltage SF6 circuit breaker designed for 126kV (110kV class) power transmission and distribution systems. It uses SF6 gas as insulation and arc extinguishing medium, equipped with hydraulic operating mechanism, and complies with IEC62271 and GB standards.
This breaker is mainly used in power substations, power plants, industrial power systems and grid projects to control and protect circuits. It can reliably switch load current and short-circuit current, with stable performance, low gas leakage rate, long mechanical life and strong outdoor adaptability.
It is widely used in 110kV/126kV power grid construction, renovation and new energy power stations, providing safe and reliable protection for high voltage power equipment.
