Overview
GTXGN-12 AC Metal Solid Insulated Ring Main Unit is a fully insulated, completely sealed, and maintenance-free solid insulated vacuum switchgear device.
All high-voltage live components are encapsulated with excellent insulating epoxy resin materials, integrating the vacuum arc extinguishing chamber, main conductive circuit, and insulating support into a single unit. The functional units are connected through fully insulated solid busbars.
As a result, the entire switchgear is unaffected by external environmental factors, ensuring the reliability of operation and the safety of personnel.
This ring main unit features a simple structure, flexible operation, reliable interlocking, and convenient installation. It is suitable for a 50Hz,12 kV power system and is widely used in industrial and civilian cable ring networks and distribution terminal projects. It serves to receive and distribute electrical energy, particularly suitable for urban residential area distribution, small substations, switching stations, cable branching boxes, box-type substations, and various locations such as shopping malls, airports, subways, wind power generation, hospitals, stadiums, railways, and tunnels.
Due to its fully insulated, completely sealed, and fully shielded advantages, this product is especially suitable for use in harsh environments such as high altitudes, high temperatures, humid heat, extreme cold, and areas with severe pollution.
