Introduction
ARSM16 series SF6 Gas-insulated Ring Main Unit(GIS) is an extensible, SF6 Gas-insulated RMU(GIS), with rated voltage of 12/24 kV. All its HV live parts are contained in an air-tight gas tank, which is made from stainless steel of 3mm. The whole switching assembly is SF6 insulated, and free from any external influence, ensuring it great reliability of service and maintenance free. By plug-in type busbar extension, ARSM16 series SF6 Gas-insulated RMU(GIS) can be of free combination and full modularization. The busbar extension has passed type test for power and thermal stability, and is fully insulated and shielded, exhibiting high reliability and safety. ARSM16 series SF6 Gas-insulated Ring Main unit is suitable for all MV network up to 24 kV, all compact power stations, power distribution substations in all important industries, such as petrol-chemical industry, metallurgical and mining industries, and all transformer substations and wind power system.
Advanced process technique for gas tank
The digital-controlled laser cutting and punching system and three-dimension and five-axis laser welding system imported from Germany and Japan with ensure the gas tightness and uniformity of all gas tanks.
The fully automatic and integral helium leak detection system, through detecting of Helium leakage by mass spectrograph, brings gas leakage rate per year down to less than 0.02%, ensuring the life span of gas tank of over 30 years.
Advanced process technique for parts
All epoxy resin insulated parts, including insulated poles, are manufactured by fully-automatic and digitally controlled epoxy resin vacuum mixing/pressure gelatinizing system.
The busbar connector, cable connector, end-plug and other silicone rubber insulated parts are manufactured by fully-automatic and digitally controlled silicone rubber mixing/pressure gelatinizing system.
Excellent solutions for products
With small and compact structure, the basic functional units C, F, V and D have uniform dimension: 325x751x1500mm (width x depth x height)
Complete solutions
Single version: load break switch unit, switch-fuse unit, vacuum circuit breaker unit, busbar subsection unit, cable unit, metering unit, etc.
Block version can be made up of two, three, four, five or six functional units.
Single units and block version can be connected by busbar connectors flexibly.
Strong adaptability to the environment
The primary conductive system is fully sealed in the SF6 gas tank and will not be influenced by the outside environment, independent of the impact of dew, dust, salt fog, etc. Therefore, ARSM16 series can be applied at various severe service conditions.
