Overview

The LW6-24 outdoor high-voltage sulfur hexafluoride circuit breaker is a versatile, three-phase AC 50HZ outdoor switchgear designed to control and protect 24KV power transmission and transformation systems. Additionally, it can be utilized as a connecting circuit breaker and a combination of opening and closing devices. This advanced circuit breaker employs the "thermal expansion+auxiliary blowing" principle to intelligently extinguish arcs, and is equipped with a reliable CT10 spring operating mechanism. Furthermore, it meets the stringent requirements of both the GB/T1984-2014 "AC High Voltage Circuit Breakers" standard and the International Electrotechnical Commission's IEC62271-100:2001 "High Voltage Switchgear and Control Equipment - Part 100: High Voltage AC Circuit Breakers" standard.
