Product Introduction
General
KYN28 indoor metal-clad switchgear is a complete power distribution device for 3.6~24kV,3-phase AC50/60Hz,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 IEC,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker,it can also be used with VD4 from ABB, 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.
