KYN28-12 Metal-clad Withdrawable Enclosed switchgear power cubicles

distribution switchboard air insulated type switchge

KYN28 indoor metal-clad withdrawable switchgear(hereafter short as switchgear) is a complete power distribution device for 3.6~24KV, 3 phase AC 50Hz, single bus sectionalized system. It is main 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 be used with VD4 from ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc. It is truly a power distribution deviece 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.
