The KYN72-40.5 armored removable metal-enclosed switchgear is suitable for three-phase AC 50Hz, rated voltage 40.5kV single busbar and single busbar segmented power systems. It is mainly used in power plants, substations, industrial and mining enterprises, and high-rise buildings for power transformation and distribution to receive and distribute electrical energy, as well as for circuit control, protection, and monitoring. It meets the requirements of standards such as IEC298, GB3906, and DL/T404.

Main Features:

The product adopts high-strength, corrosion-resistant aluminum-zinc coated sheets that are thickly folded and formed, connected by rivets and bolts with pull-rivet nuts. The entire cabinet has no welding, with precise dimensions, strong rigidity, and good interchangeability

Uses composite insulation and optimized electrode shapes to make the cabinet structure compact and reduce floor space

Employs a four-link shutter mechanism and insulated contact boxes instead of metal partitions, significantly enhancing cabinet insulation performance

Features a ball screw propulsion mechanism, making handcart advancement (withdrawal) highly labor-saving

Equipped with "five-prevention" interlocks to ensure personnel safety, with convenient operation and reliable performance

High-rigidity cabinet frame, reasonable pressure release channels, and reliable door and lock design prevent internal faults from causing harm to personnel. The switchgear has passed internal fault tests at Xi'an High Voltage Apparatus Research Institute
