Overview The load switch is a kind of switchgear with a simple arc extinguishing device. It uses SF6 gas as the insulation and arc extinguishing medium. It can be used as the closing and breaking load current and overload current. It can also be used as the closing and breaking no-load. Lines, no-load transformers and capacitor banks, etc., all three-position load switches with on, off and grounding functions are simple in structure and affordable. In addition to long life, strong breaking fo...
