Switch Cabinet i-AY6 Series Removable AC Metal-Clad Swtichgear

Product Description
Product Overview Overview
he Mobile AC Metal Enclosed Switch Equipment at IE grade (hereinafter referred to as Switchgear) is an indoor cubicle switchboard, with the three-phase AC rated voltage of 7.2～12kV, and three-phase AC of 50/60Hz. It combines the latest design features, and is safe in operation, good technique performance and improved resistance of internal electric arc. It is applicable to the second generation and third generation nuclear power plants: nuclear island and conventional island of AP1000, CAP1400, CPR1000(M310) and ACPR1000 and electric system in BOP. It also meets the safety grade required in IE grade medium voltage switch used for nuclear power plants. The EVH9 series vacuum circuit breaker equipped meets the expected life of 60 years, and the typical earthquake response spectrum covers the spectrum of all nuclear power plants where construction is ongoing or to be constructed in China. It is also applied to ideal distribution equipment for power plants, industrial and mining enterprises, power system and public network, and control, protect and monitor the circuits and equipment.
