KYN61-40.5 35kV medium voltage panels
Gengeral
We are KYN61-40.5 35kVmedium voltage panels manufacturer (following short for switchgears),used in 35kV three-phase AC 50Hz power system.Safety is ingrained in its DNA. It intelligently isolates live parts within independent metal compartments and features a robust mechanical interlock system that completely prevents misoperation. In the event of an internal arc fault, it acts like an airbag-instantly releasing pressure through a specially designed relief channel to minimize risk. It's a true "safety guardian."
