  • What is SF6 Circuit Breaker? Construction, Working

    SF 6 gas is suffocating to some extent. In the case of leakage in the breaker tank, the SF 6 gas being heavier than air and hence SF 6 are settled in the surroundings and lead to the suffocation of the operating personnel. The entrance of moisture in the SF 6 breaker tank is very harmful to the breaker, and it causes several failures.
