GZS1 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 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.
