KYN61-40.5 Armored Withdrawable AC Metal-Enclosed Switchgear (hereinafter referred to as switchgear) is suitable for three-phase AC 50Hz, 35kV single busbar and single busbar sectioned power systems. It is mainly used in power plants, substations, industrial and mining enterprises, and high-rise buildings for receiving and distributing electrical energy, as well as for controlling, protecting and monitoring circuits. The switchgear meets the requirements of standards such as IEC62271-200:2003, GB3906-2006 and DL404-91, and is equipped with complete "five-prevention" interlocking functions.

The switchgear is equipped with ZN85-40.5(3AV3) vacuum circuit breaker or SF6 circuit breaker series. It adopts heat-shrinkable insulating materials and epoxy coating insulation process, with optimized electrode shape. The compact cabinet structure reduces floor space. The switchgear enclosure is made of high-quality aluminum-zinc coated steel plates processed by CNC sheet metal technology, and assembled with high-strength bolts, nuts and rivet nuts. The components surface adopts powder coating or galvanizing process. All functional compartments of the switchgear are separated by metal partitions and equipped with independent pressure relief channels.
