  • Mitsubishi Electric Develops New Gas-insulated Switchgear

    In the switchgear, compressed SF6 gas is injected between a metal high-voltage conductor and a grounded tank. If the conductor’s metal surfaces are not coated, surface roughness of even just several μm can lead to electric discharges and thereby diminish the dielectric performance of the SF6 gas.
