sf6 circuit breaker Equipment rental

In the closed position of the SF6 circuit breaker, the contacts remain surrounded by SF6 gas at a pressure of about 28 kg/cm2.When the breaker operates, the moving contact is pulled apart and an arc is struck between the contacts. The movement of the moving contact is synchronised with the opening of a valve which permits SF6
