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.
