LW8-40.5 33kV Outdoor High Voltage SF6 Circuit Breaker

General Introduction

LW8A-40.5 Type 12kv  24kv  33kv Outdoor Sf6 Circuit Breaker  is an outdoor device used in AC 50HZ three-phase 40.5KV power system. It is applicable to locations that need frequent operating in rated current or under repeatedly on/off short circuit current. Containing the current transformer for measurement and protection, it can directly replace SW2-35 less oil circuit breaker and various types of oil circuit breaker with transition bracket. It can also be used as a tie breaker and switching capacitor group situations with CT14 type spring mechanism.
