MV KYN61-40.5 metal-clad movable switchgear is suitable for 40.5 kV rated voltage power distribution system.

Features:

  • Switchgear is designed of assembly structure and circuit breaker is handcart floor model.
  • It is equipped with advanced composite insulation vacuum circuit breakers featuring good exchangeability and simple change.
  • There is lead screw nut propulsion mechanism in handcart frame, making the handcart movement easy. And this design can prevent from fault operation which may damage the propulsion mechanism.
  • All the operations can be carried out at switchgear-closed condition.
  • The interlockings of main switch, handcart and switchgear door adopt compulsory mechanical locking, and this design meets five protection function.
  • The space of cable chamber is wide and many cables can be connected in the cable chamber.
  • Quick earthing switch is used for earthing and loop short circuit.
  • The protection degree of enclosure is IP3X and IP2X at the handcart door opening condition.
  • The product conforms to GB/T11022-1999, GB3906-1991 and DL404-1997. It is manufactured according to international standard of IEC-298.
  • Overall dimensions (width × depth × height): 1400 mm × 2800 mm × 2600 mm.
