KYN28-12 removable AC metal-clad switchgear (short for panel as below) is a new product. It will be a substitute for old fashioned metal-enclosed switchgear, such as KYN-12, JYN-12, GFC-12, etc. The panel applies to 3.6~12kV 3 phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It accords with standard of IEC62271-200, IEC60694, GB3906.

Product features
●Increase the heat capacity of the adapter, and significantly
reduce additional temperature rise of connector, spacer plates due
to the temperature rise in adapters.
●Clear and reliable division between functional units and
compartments.
●Flat-mounted arrangement of bus bar permits good driving and
thermal stability.
●The connecting with external cables is completed within the cable
compartment, and the cable can be pulled in and out. The zero
sequence current transformers are set in the cable compartment,
easy for installation and maintenance.
●By the reduced current limiting reactors' matched short-circuit
current, the bus bar's voltage could be stabilized at a certain
value, the parts'short-circuit components strength requirement
could also be reduced.
●The drawer unit has sufficient number of secondary plug-in
components to meet the requirement for the numbers of connection
points for computer interface and automatic control circuits.
