Overview

The LW8-40.5AG outdoor high-voltage sulfur hexafluoride circuit breaker is designed for controlling and protecting 40.5KV transmission and transformation systems in outdoor settings with a frequency of 50HZ. It can function as both a connecting circuit breaker and a device for opening and closing. This circuit breaker uses the "thermal expansion+auxiliary blowing" intelligent arc extinguishing principle and is operated by a CT10 spring mechanism. It conforms to the standards outlined in GB/T1984-2014 for AC High Voltage Circuit Breakers. It meets the criteria set by the International Electrotechnical Commission standard IEC62271-100:2001 for High Voltage Switchgear and Control Equipment - Part 100: High Voltage AC Circuit Breakers.
