Indoor Metal-Clad Withdrawable Switchgear:
General introduction: KYN28 (GZS1) series in-door metal-clad withdrawable switchgear
is a new switchgear empoldered in the base of extensively assimilating the same
sort s advantages both home and abroad. It is extensively applied in 6-10k V
distribution equipment in power plants, substations, industrial and mining enterprises,
high-buildings, for single-busbar system s power receiving and distribution.
Characteristics:
1) It can install VD4 vacuum circuit breaker imported or VSI vacuum circuit breaker
made in China
2) It has the perfect capability of "Five Prevention", and conforms to such standards
as GB3906, DL403, DL/T404, DL/T539
3) The cable compartment has enough room to connect several roots of cable, and
simple installation and maintenance
4) The cubicle is wall mounting, so as to reduce the area taken-up
5) The functional trucks can be conveniently interchanged
6) The degree of protection for the cubicle is IP4x
