ACthree-phaseindustrial

General KYN28 indoor metal-clad withdrawable switchgear(hereinafter short as switchgear)is a complete power distribution device for 3.6~24kV,3-phase AC 50Hz,single-bus and single-bus sectionalized system.　It is mainly used for power transmission of middle/small generators in power plants;　power receiving,　transmission for substations in power distribution and power system of factories, mines and enterprises,　and starting of large high-voltage motor,　etc.,so as to control,　protect and monitor the system.　The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker,　it can also be used with VD4 from ABB,3AH5 from Siemens domestic ZN65A,and VB2 from GE,　etc.,it is truly a power distribution device with good performance. In order to meet the requirement for wall mounting and front-end maintenance,　the switchgear is equipped with a special current transformer,　so that the operator can maintain and inspect it in front of the cubicle. Service environment a) Air temperature: Maximum temperature: +40℃; Minimum temperature:-15℃ b) Humidity: Monthly average humidity 95%; Daily average humidity 90% . c) Altitude above sea level: Maximum installation altitude: 1000M. d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc. e) No frequent violent shake
