GN-GTXGN-12/24 Solid Insulated Ring Main Unit
Short Description:
GN-GTXGN-12/24 AC metal solid insulated ring network switchgear is a fully insulated, fully sealed, maintenance free solid insulated vacuum switchgear. All high-voltage live parts are cast with epoxy resin material with excellent insulation performance, organically combining the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators
Product details
Overview：
GN-GTXGN-12/24 AC metal solid insulated ring network switchgear is a fully insulated, fully sealed, maintenance free solid insulated vacuum switchgear. All high-voltage live parts are cast with epoxy resin material with excellent insulation performance, organically combining the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators
This ring main unit has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation, and is suitable for 50Hz, 12/24KV power systems. It is widely used in industrial and civil cable ring networks and distribution network terminal projects, as well as for the reception and distribution of electrical energy. It is particularly suitable for use in urban residential areas, small substations, switch stations, cable branch boxes, box type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, sports stadiums, railways, tunnels and other places.
Due to its advantages of full insulation, full sealing, and full shielding, this product is particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and severe pollution.
CLASSIFICATION：
According to the type of switch, it is divided into load switch with grounding assembly (referred to as C module), load switch without grounding assembly (referred to as CB module), circuit breaker with grounding assembly (referred to as V module), circuit breaker without grounding assembly (referred to as VB module), circuit breaker interconnection switch (referred to as VZ module), load switch+fuse combination switch assembly (referred to as F module), and isolation switch assembly (referred to as G module).

Note: If ordering this product exceeds the above conditions, please consult with our company.
Safety and Environmental Protection：
□Visual fracture of isolation knife
There is a clear isolation fracture visible window in front of the cabinet, which allows for viewing of three working positions: isolation closing, isolation separation, and grounding closing. This facilitates on-site personnel to inspect and determine the position of the isolation knife, making it very safe
□Internal combustion arc design
Internal arc pressure valve: When an arc occurs inside the product, the pressure relief valve will release the pressure and discharge the arc into the cable trench to avoid accidental operation.
□Green and environmentally friendly
Designed with environmentally friendly materials, without using SF6 gas as an arc extinguishing medium or insulation, it does not pollute the environment. The primary circuit adopts the minimum contact design to ensure low energy consumption during operation,
