GTDXF囗-12 AC metal solid insulated ring main switchgear
AC metal solid insulated ring main switchgear is a fully insulated, fully sealed, and 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. This ring main unit has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12 kV power systems and widely used in industrial and civil cable ring networks and distribution network terminal projects. It is used for the reception and distribution of electrical energy, especially for urban residential distribution, 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. Due to its advantages of full insulation, full sealing, and full shielding, this product is particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and serious pollution.
