  • Description
  • Characteristic
  • Parameter
  • Airing ® series of environmentally friendly gas insulated RMU adopt environmentally friendly gas as insulation medium to reflect harmony between modern industrial manufacturing and nature and to practice the social responsibility of modern manufacturing enterprises for ecological civilization.
    The key unit of Airing ® series of environmentally friendly gas insulated RMU uses a patented self-energy load switch and a super low resistance of the vacuum circuit breaker to make the primary live parts sealing in a micro-positive pressure stainless steel gas tank which is filled with SF6 gas, isolate with the outside environment. It ensures the switch devices and all live parts in the gas tank which are not affected by external environment fluctuations to realize the equipment maintenance-free, improve power supply reliability, enhance the personnel safety and meet the needs of economic stable operation.
    Airing ® series of environmentally friendly gas insulated RMU is widely used in urban distribution network, intelligent micro grid, commercial real estate, municipal engineering, light industry, residential area and so on . It practices the concept of economic reliability and create value for customers persistently.

    • Bases on standardized design.
    • Based on the concept of environmental protection, environmental friendly.
    • Rated voltage for12kV.
    • All live parts are sealing in a micro-positive pressure stainless steel tank which is suitable for distribution places where salt mist, moisture or pollution is easy to occur.
    • Withstand internal arc faults ability.
    • The earthing switch has ability to the short circuit making current.
    • Mechanical interlock ensures correct and reliable sequential operation.
    • Cabinet width for 450mm or  500mm*, compact structure, lightweight design, saving floor area.
