The main feature of KYN61-40.5 armoured removable AC metal-clad switchgear equipment (hereinafter referred to as "switchgear") is the configuration of ZN85-40.5, VD4, and VB2 fully insulated vacuum circuit breakers with spring operating mechanisms. The cabinet is assembled from aluminium-zinc plates, which enhances the matching precision between the handcart and the cabinet. The handcart is extremely lightweight for extraction and demonstrates strong interchangeability, featuring an aesthetic appearance, comprehensive design, and safe & reliable operation.


This product is applied in 35kV three-phase AC 50Hz power systems, serving as power receiving and distributing equipment in power plants, substations, and industrial & mining enterprise switchrooms, with functions of control, protection, and monitoring.
