  • Major components you can spot while looking at HV/EHV

    Sep 18, 2019The circuit breaker in a gas insulated system is metal-clad and utilises SF6 gas, both for insulation and fault interruption. The SF6 gas pressure in a circuit breaker is around 0.65 MPa. The circuit breaker is directly connected to either current transformers or the isolators in gas.
