ZHEJIANG LINGAO ELECTRICITY

The main switch utilizes vacuum arc extinguishing and SF6 gas insulation. The enclosure incorporates gas-sealed, explosion-proof, and insulated construction technologies imported from Japan, Germany, and France, resulting in excellent overall sealing performance. The internal SF6 gas filling prevents leakage and is unaffected by the external environment. The spring operating mechanism is miniaturized and optimized for performance, resulting in operational reliability far superior to traditional domestic spring mechanisms.
