KYN28 MV electrical equipment withdrawable Metal-clad Enclosed switchgear distribution
KYN28 -24 Type switch cabinet is three phase AC50Hz,rated voltage 24KV indoor power distribution equipment . As power plants ,substations ,industrial &mining enterprises to accept amd distribute of electric energy to control ,protect and monitor ,circuit ,ect.Can also be used to control the place of frequent operation .
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 .
Simple and effective ‘Five Anti’lockout to prevent misuse
Can be equipped with VS1.VD4,3AH vacuum contactors,etc
Can be equipped with voltage transformer hancart,isolation handcart,fuses ,ect,Used ,Used same use interchangeable.
The switch cabinet can be wall mounted ,front cabinet maintenance,reduce floor space .
The circuit breaker compartment and cable compartment heater can be installed separately ,to prevent condenstation and corrosion ;
Cable ample room space,can be connected to a plurality of cables .
Shell protection grade IP4*,among compartment protection class IP2*:
The meterial can be gavanized sheet can be deposited aluminum and zinc plate production .
