KYN28 metal-clad switchgear is used in the power distribution device of 3.6~24kV, three-phase, AC, 50/60Hz, single busbar section system. It is mostly used for power transmission of small and medium-sized generators in power plants, power reception and transmission of power distribution in mining enterprises or substations of power systems, and start-up of large high-voltage motors. Its function is to control, protect and monitor the system.
This series of switchgear complies with IEC and GB3906-91 standards and can be used with vacuum circuit breakers such as domestic VS1, ABB VD4, Siemens domestic ZN65A 3AH5, GE VB2, etc.
In order to meet the requirements of wall-mounted and front-end maintenance, the switch cabinet we made is equipped with a special current transformer for the operator to perform maintenance and inspection in front of the cabinet.
