Wholesale ODM Zg6 Series Sf6 Metal Enclosed Gas Insulation Switchgear (C-GIS) Vvvv+Kvvvv

Short Description:

XGN-12 series unit type AC metal closed ring network high voltage switchgear electrical cabinet  is a fully insulated, fully sealed, and maintenance-free solid insulated vacuum switchgear. All high-voltage live parts are molded with epoxy resin material with excellent insulation performance, and the vacuum interrupter, main conductive circuit, insulating support, etc. are organically combined into a whole, and the functional units are connected by a fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, and the reliability of the operation of the device and the safety of the operator can be ensured. Because the product has the advantages of full insulation, full sealing, and full shielding, it is especially suitable for use in areas with high altitude, high temperature, mixed heat, severe cold, and severe pollution.
