Introduction 
The Air-12/T630-25 environmental gas insulation metal-enclosed switchgear uses a vacuum interrupter for arc extinguishing, with environmental gas as the primary insulating medium and a small number of solid insulating support components. The main loop is completely unencapsulated. Under normal operation, the gage pressure is zero or slightly positive (the gas pressure in the enclosure is ≤ 0.02 MPa). Moreover, as for the power distribution switchgear, the inter-phase and phase-to-ground insulation capability meets the requirements for air insulation under zero gage pressure.
