Product Description

   Kexun is a supplier specializing in the production of power transmission and transformation equipment in China.Solid Insulated Closed Medium Voltage Switch Equipment is one of KEXR's main products. It uses solid insulation material as the main insulation medium, providing a perfect series of solutions for power grid upgrading and distribution users.
  Product overview
KXSGN-12 Solid Insulated Closed Medium Voltage Switch Equipment have many schemes such as circuit breaker protection, transformer protection, load control, fuse combination electricity, PT power supply, bus coupler lifting and so on. This product can be used as power system ring network distribution equipment, and can also be used as power distribution equipment for urban construction of industrial and mining enterprises, with the characteristics of multi-function and versatility.
Solid Insulated Closed Medium Voltage Switch Equipment adopt solid insulating material as the main insulating medium, the vacuum interrupter, conductive connection, disconnector, grounding switch, main bus, branch bus and other main electrical circuits are wrapped and packaged with solid insulating medium into one or several modules with certain functions, which can be combined or expanded again and have full insulation and tightness.
