  • Parameter
  • Enerswit+® Series SF6 gas insulated ring network cabinet is a series of SF6 gas insulated ring network cabinet, which is introduced by Xiamen Huadian switchgear Co., Ltd. based on the product design concept of safety, reliability, economy and compactness, including the D circuit breaker scheme, C load switch scheme and t load switch fuse combination scheme of 12kV and 24kV voltage levels. It adopts the rotary compressor type load switch with invention patent, the ultra-low resistance vacuum arc extinguishing chamber and the primary live parts fully sealed in the stainless steel gas box filled with SF6 gas welded by the robot, which is free from the impact of external environment, has good reliability, safety, economy, flexibility, inherits the characteristics of compact structure and maintenance free.
    Enerswit+® series SF6 gas insulated ring network cabinets are widely used in urban distribution network, smart micro grid, commercial real estate, municipal engineering, light industry, residential areas and other fields, practicing economic concepts, and continuously creating value for customers.


  • Enerswit+ ® series load switch adopts patented rotary pneumatic arc-extinguishing technology.

    Enerswit+ ® series vacuum circuit breaker adopts a vacuum arc-extinguishing chamber with ultra-low resistance.

    Enerswit+ ® series stainless steel gas box is welded by advanced robot welding technology. 

    Enerswit+ ® series adheres to the concept of environmental protection, and more than 90% materials can be recycled.

    Enerswit+ ® series adopts modular design, featuring flexible expansion and diverse solutions.

    Enerswit+ ® series has optional visual observation window of isolated fracture, safe and reliable.

    Enerswit+ ® series is provided with a reliable five-prevention interlock to prevent misoperation.
