Metal-clad Double-layer Draw-out Type Switchgear KSN1-12

   KSN1-12 (KYN39-12) Metal-clad Two-layer Draw-out Type Switchgear is a kind of indoor complete set of electric apparatus with 3-10 kV, three phases alternative current 50HZ single busbar and single busbar segment system. It is mainly used in power plants, industrial and mining enterprises for power distribution, medium and small size dynamo and for power feeding and electric power supply in the secondary substation of power supply system. It can control, protect and monitor the start of HV electromotor.

Product feature :
      This switchgear is of two-layer structure matched with inner VS1-12 vacuum circuit breaker . It meets specification of GB3906-91, IEC 298 standard and having 5-protective functions and it featured by:
      a. It is specially designed to reduce occupied area of substation.
      b. Matched good vacuum circuit breaker, and it has the function of middle mounted switchgear.
      c. Adopting international fashioned assembly combination structures, completely metal-clad, and it is separated completely.
      d. Aluminum zinc coated steel plate enclosure is not necessary to do any surface treatment to meet requirement of anti-corrosion.
      e. Accord with the standard of IEC298, GB3906-91, it is an ideal import substitute.
