LW30-252(T)/T/Y4000-50 Type High Voltage AC SF6 Tank Circuit Breaker

The LW30-252T high voltage AC SF₆ tank circuit breaker integrates the circuit breaker and current transformer into a cohesive unit. The arc-extinguishing chamber is horizontally installed within a grounded aluminum alloy casing, with current transformers positioned beneath the outgoing line bushings on both sides. The phase-segregated operating circuit breaker (capable of electrical linkage) is equipped with either a CT26 spring operating mechanism or a CTY-5 hydraulic spring mechanism, while the three-phase mechanically linked circuit breaker utilizes a CTY-10 hydraulic spring mechanism. The product boasts a minimal number of components, a simple and compact layout, overall robustness and durability, excellent mechanical characteristics, and high reliability. All critical components are machined using CNC and machining center equipment, ensuring reliable operation for thirty years and a mechanical lifespan of up to 10,000 cycles. This product is suitable for three-phase AC 50Hz, 220kV power systems, and can be used for system control, protection, and measurement, as well as serving as a liaison circuit breaker.
