Product Introduction

The GTXGN-12/630 series solid fully insulated closed-ring switchgear is a fully insulated, fully sealed, and maintenance-free solid insulated vacuum switchgear. All high-voltage live parts are encapsulated with high-performance epoxy resin, forming an integrated structure that combines the vacuum arc extinguishing chamber, main conductive circuit, and insulating support. The functional units are connected by fully insulated solid busbars. As a result, the entire switchgear is not affected by external environmental conditions, ensuring the reliability of the equipment and the safety of operators. This ring network cabinet features a simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12kV power systems and is widely used in industrial and residential cable ring networks, distribution network terminal projects, for receiving and distributing electrical energy. It is especially suited for applications in urban residential area distribution, small substations, switchgear stations, cable branch boxes, box-type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, stadiums, railways, tunnels, and other locations.

Due to its fully insulated, fully sealed, and fully shielded design, this product is particularly suitable for use in harsh environments such as high altitudes, high temperatures, humidity, severe cold, and areas with serious pollution.
