The FLN36-12D load switch has both the main circuit and grounding circuit sealed within an insulating shell made by APGI technique casting in epoxy resin, offering excellent insulation properties and resistance to polluted environments. The insulating shell is composed of two insulating covers, with the internal space filled with 0.4bar of SF6 gas. The lower insulating cover features explosion-proof measures to ensure that in the event of an accident, over-pressurized SF6 gas is directly directed towards the cabinet's rear channel, ensuring personal safety.
