Product Description

Summary:

KYN28 indoor metal-clad withdrawable switchgear(hereinafter short as switchgear)is a complete power distribution device for 3.6~24kV,3-phase AC 50Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of medium/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,IEC60298,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.

Structure Description:

Switchgear are requested designed according to GB3906 and Ie 298.The whole switchgear can be extracted from the cabinet and spare parts (trolley) two components ,Cabinet structure are made of aluminum deposited zine plate or galvanized plate bolted combination forming a metal partition separationg the part of the circut break room,main busbar room cable room and relay control room.and all metal construction were grounded ,each com-partment of the main circuit system has separste pressure release channel,In the cable compartment can be set to 40*6mm ground busbar .
