TPR7a-12(24) /630 SF6 gas-insulated ring main unit
TPR7a series ring main unit is a new type SF6 gas-insulated MV switchgear we develop through applying the computer simulation technology, and based on years of our experiences in product design and manufacturing. All live parts of primary voltage are completely sealed in SF6 gas tank that is formed by welding 3 mm thick stainless steel, which makes the size small and compact. The whole switchgear is not affected by external environment. Fully insulated and fully sealed structure. It is effective in flood control and pollution resistance, suitable for various harsh environments. Flexible extension (unit non-segregated type) structure, satisfying the needs for flexible use of compact switchgear. It is widely used in many fields, such as urban grid renovation of power system, distribution station and load center station, petrochemical industry, iron and steel industry and mining industry, general enterprises and institutions, high-rise buildings.
TPR8-12/630 solid-insulated metal enclosed ring main unit
TPR8 series solid-insulated metal enclosed switchgear is a new type all condition and environmental-friendly complete switchgear that we research and develop based on extensive absorption of the advantages of similar products at home and abroad. All live parts are sealed in epoxy switch bushing and silicone rubber enclosed bus, which integrates the vacuum interrupter, main conductive circuit and insulation support to achieve a fully-insulated, fully-sealed and maintenance-free structure. It can be used to receive and distribute 7.2-12kV network electric energy, and for control, protection and monitoring of circuits. It is widely used in such fields as substations and industrial power distribution.
XGN118-12/630 environmental-friendly gas-insulated metal enclosed ring main unit
XGN118 environmental-friendly gas-insulated metal enclosed switchgear is a new type environmental-friendly complete switchgear that we develop by applying advance technologies such as the 3D modeling technology, finite element simulation analysis technology and automated welding technology. All primary live components and insulation pieces are sealed in a 3 mm thick stainless steel enclosed box, to which dry air with zero gauge pressure or low pressure is filled; it is an ideal substitute for traditional SF6 insulated ring main unit, featured by maintenance-free, high reliability, modularization, intelligence and greening. It is widely used in 10kV power distribution.
XGN15-12(24) air insulated metal enclosed ring main unit
XGN15(TPS) series indoor HV ring main unit is an indoor air-insulated metal enclosed switchgear of modular compact design. It is featured by small size, simple structure, flexible operation and reliable interlocking. The SF6 load switch has three world patents for drum integrated pouring, rear leakage channel and semilunar visible window, which makes the switchgear more safe and reliable. It is especially suitable for the urban distribution network, small secondary distribution stations, opening/closing substations, industrial and mining enterprises, shopping malls, airports, wind power generation plants, hospitals, etc.
