Solid Insulated Ac Metal Ring Switchgear

NSGTG solid insulated AC metal ring network switchgear is a fully insulated, fully sealed, maintenance free solid insulated vacuum switchgear. All high-voltage live parts are cast with epoxy resin material with excellent insulation performance, organically combining the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators.

NSGTG solid insulated AC metal ring network switchgear has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12KV power systems and widely used in industrial and civil cable ring networks and distribution network terminal projects. As a means of receiving and distributing electrical energy, it is particularly suitable for use in urban residential areas, small substations, switch stations, cable branch boxes, box type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, sports stadiums, railways, tunnels and other places.

NSGTG solid insulated AC metal ring network switchgear has the advantages of full insulation, full sealing, and full shielding, making it particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and severe pollution.
