General
KYN61-40.5 Switchgear is equipped with advanced ZN85A vacuum circuit breaker. VD4 vacuum circuit breaker cabinet uses the assembly structure to increases the quality of appearance and manufacturing precision; Bus bar uses heat insulation materials or the insulation of the epoxy coating methods to optimize the electrode shape, compact the structure of the cabinet, and possess perfect function of "five prevention"
KYN61-40.5 Switchgear is applicable in the power system of 40.5kV three-phase AC 50Hz, which is used to receive and distribute power as well as control, protect and monitor the circuit of power plant, substation and industrial and mining enterprises and high-rise buildings. In addition to the widely used for general power system, it can also be used in place of frequent operation. Using environment conditions are according to GB3906 "3.6-40.5kV AC Metal-enclosed switchgear"
