SIS – Solid Insulated Ring Main Units are ring main
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 casted with epoxy resin materials with excellent insulation performance, and the vacuum interrupter, main conductive circuit, insulation support, etc. are organically combined as a whole, and the functional units are connected through fully insulated solid busbars. Therefore, the entire switchgear 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. It is suitable for 50Hz, 12 kV power systems, and is widely used in industrial and civil cable ring networks and distribution network terminal projects. It is especially suitable for power distribution in urban residential areas, small substations, switching stations, cable branch boxes, box-type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power, hospitals, stadiums, railways, tunnels, etc. 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 pollution, etc.
