I Overview
Armored KYN61-40.5 AC metal enclosed switch away cabinet (hereinafter referred to as Switchgear) is used for three-phase AC 50Hz, 40.5kV single busbar and single busbar system, power distribution equipment, mainly for power plants, substations industrial and mining enterprises in the transformation and distribution center for receiving and distributing electric energy use, and the circuit control, protection and monitoring, but also for frequent operation place.
Switchgear to meet GB3906, GB/T11022, DL404, IEC60298 and other standards, have improved the "Five Anti" feature.
II Environmental conditions of normal use
