SF6 circuit breaker LW58A

dead-tankhigh-voltage

LW58A Outdoor High-voltage AC SF₆ Tank Circuit Breaker features strong environmental adaptability, high reliability, and maintenance-free operation. With a rated voltage covering 40.5-800kV, it provides three-pole intertripping & pole-discrepancy operation solutions. Suitable for high-voltage power transmission and distribution applications including substations and distribution networks. Compact design High reliability Superior interrupting performance Features 01 Compact design Integrated with external CT, reduced product footprint, low center of gravity, and excellent seismic performance. 02 High reliability Adopts a new integrated die-cast aluminum base spring operating mechanism. Compact structural design ensures stable output performance, high reliability, and maintenance-free operation. Mechanical life meets M2 class requirements. 03 Superior interrupting performance Utilizes dual-motion self-energy & assisted compression arc-extinguishing technology. Delivers strong interrupting capability across the entire series (up to 63kA), suitable for diverse complex conditions. 04 Excellent sealing performance Employs diaphragm sealing structure. SF₆ gas leakage rate ≤0.05% per year.
