Product Description

 

Product Description

CA-SIS series solid fully insulated closed ring network switchgear is a fully insulated, fully sealed, maintenance-free solid insulated vacuum switchgear. All high-voltage live parts are made of epoxy resin material with excellent insulation performance, and the vacuum interrupter, main conductive circuit, insulating support, etc. are organically integrated, and each functional unit is connected by a fully insulated solid busbar. Therefore, the entire switch cabinet is not affected by the external environment, which can ensure the reliability of equipment operation and the safety of operators.
The ring network cabinet has the characteristics of simple structure, flexible operation, reliable interlocking and convenient installation. Suitable for 50Hz, 12kV power system, widely used in industrial and civil cable ring network and distribution network terminal projects. It is especially suitable for power distribution in urban residential areas, small substations, switch stations, cable branch boxes, registered substations, industrial and mining enterprises, shopping malls, airports, subways, wind power, hospitals, stadiums, railways, tunnels and other places. use. Because the product has the advantages of full insulation, full sealing, and full shielding, it is especially suitable for use in areas with harsh environments such as high altitude, high temperature, humid heat, severe cold, and severe pollution.
