KYN61-40.5 High-voltage Switchgear


KYN61-40.5 - indoor metal-clad withdraw-able high voltage switchgear, designed for 40.5 kV 3-phase AC 50Hz single busbar and single busbar segmented system. 

It is mainly applicable in power plant, substation, industrial and mining enterprise to receive and distribute power with the functions of controlling,protecting and monitoring circuits, and can also be used at the sites with frequent operations.

  • Complies with IEC60398, IEC60694, GB3906, GB1984 and DL/T404 standard.

  • Good compatibility with various type of circuit breakers.

  • Stable and reliable performance.

  • Easy maintenance and long service life.

  • Effective five-safety locking device to avoid false operation;

  • Better Electrical properties. Except the insulation plates between phases, all other position adopt air insulation.

  • Humanized interface ensures easy operation. All operation can be carried out at the door closed state ,to protect the safety of the operator.

  • Quick action of pressure relief plate.

  • Concise and coordinating product appearance.

Design & Structure

  • Switchgear is designed of assembly structure.

  • Optimized electrode shape makes the structure compacted.

  • Metal clad and completely partitioned and adopt rivet connection.

  • Cabinets are made of top quality aluminum galvanized steel sheet, connected by high-intensity bolts, nut and rivet nut; the surface is galvanized. 

  • The compartments are isolated with separate pressure release system; and withdraw-ale parts are interchangeable. 

  • Ample space in cable chamber.

  • It is equipped with advanced composite insulation vacuum circuit breakers featuring good exchange-ability.

  • 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.

  • Quick earthing switch is used for earthing and loop short circuit.

  • Complete and varied main wiring scheme make system connection flexible and diverse.

Operating Condition

  • Ambient temperature: -10℃ to +45℃.

  • Altitude: ≤ 1000m

  • Relative humidity:daily average ≤ 95% ,monthly ≤ 90%.

  • Shock of earthquake:less than 8 magnitude.

  • Should not be used in fire, explosion, earthquake and chemical corrosion environments. 

Note: Please consult with manufacture for special condition and requirements.
