3.Product Standard and application

LW8A-40.5 type 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.
