Product Overview
GTXGN(SIS)-12 series solid fully insulated closed ring network switchgear is a kind of fully insulated, fully sealed, maintenance-free solid insulated vacuum switchgear. All high-voltage charged parts are cast and molded with epoxy resin material with excellent insulating property, which organically combines the vacuum interrupter room, dominant electric circuit, insulating support, etc. into a whole, and the functional units are connected through fully insulated solid converging busbar. Therefore, the whole switchgear is not affected by the external environment, which ensures the reliability of equipment operation and the safety of operators.
The ring network cabinet has the characteristics of simple structure, flexible operation, reliable interlocking, easy installation, etc. It is suitable for 50Hz, 12kV power system, widely used in industrial and civil cable ring network and distribution network terminal project, as the acceptance and distribution of electric power, especially suitable for urban residential area power distribution, small substations, open and close houses, cable branch boxes, box-type substations, industrial and mining enterprises, shopping malls, airports, subway, wind power generation, hospitals, stadiums, and other industrial and mining enterprises, shopping malls, airports, subway, wind power generation, hospitals, stadiums, and other industrial and mining enterprises. It is especially suitable for use in urban residential area power distribution, small substations, cable branch offices, box substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, stadiums, railroads, tunnels and other places.
As the product has the advantages of full insulation, full sealing and full shielding, it is especially suitable for high altitude, high temperature, hot and humid, cold, pollution and other harsh environments.
