Product Overview
The ring network cabinet GTXGN-12 solid insulation ring main unit, a professional 11 kv ring main unit and high-performance rmu switchgear serving as reliable three phase switchgear, is a fully insulated, sealed, and maintenance-free vacuum switchgear. All high-voltage live parts are cast with epoxy resin materials, ensuring excellent insulation performance. The functional units are connected with fully insulated solid busbars, making the entire ring network cabinet unaffected by the external environment, ensuring operational reliability and operator safety.
With its simple structure, flexible operation, and easy installation, this 11 kv ring main unit is ideal for 50Hz, 12kV power systems. As a compact and practical rmu switchgear and stable three phase switchgear, it is widely used in urban areas, small substations, switching stations, industrial sites, hospitals, airports, and more. The full insulation, sealing, and shielding make it perfect for harsh environments, including high altitude, high temperature, heavy humidity, and severe pollution.
Product Categories
According to the switch type, it is divided into load switch with grounding assembly (C module), load switch without grounding assembly (CB module, circuit breaker with grounding assembly (V module), circuit breaker without grounding assembly (v8 module), circuit breaker contact switch /VZ module). load switch + fuse combination switch assembly (F module), and isolation switch assembly (G module).

Application Areas
Low temperature and cold areas: There is no SF6 gas application, and there is no need to consider problems about low temperature operation of Sf6 gas. It can operate normally at -45°C
Plateau areas: There is no need to consider the impact of plateau atmospheric pressure on insulation performance.
Strong wind and sand areas: The solid insulation ring main unit has a safely protection level of iP67, and the control circuit room adopt special treatment to ensure long-term operation in strong wind and sand areas.
Coastal wet pool areas: Epoxy resin sealing, anti-moisture, and anti-sat spray corrosion, ensures long-term use in coastal areas.
Areas with high environmental protection requirements: The impact of SF6 gas on global warming has attracted great attention. The solid ring main unit eliminates SF6 gas and does not cause any pollution or harm to the environment and human body
in smart grid: Since the main switch and isolation switch can be electrically operated,the intelligent controller developed by our company can be selected to remotely control, telemeter and telecommunicate the switch equipment and substation on site, which can be used for both decentralized control and centralized control.
