Famous Cable Distribution Box Factories – KYN28A-12 Metal-clad Movable Switchgear – Changan Group Detail:
Product Summary
KYN28A- 12 indoor metal-clad movable switchgear is a complete power distribution device for 3.6kV~12kV, 3 phase AC 50/60Hz,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-voltagemotor etc., so as to control, protect and monitor the system. It complies with GB/T11022, GB/T3906, DL/T404 and other relativestandards. It has functions of preventing to push or pull the breaker’ s handcart with load, breaker’ s mistakenly open or close, shutoff the breaker when the grounding switch is on the position of close, enter into a electriferous compartment, mistakenly close the .interlock function of the grounding switch when it is electriferous.It can be used with domestic VCA and VS1 vacuum circuit breaker, itcan be used with VD4 from ABB and EV 12S from Schneider.

Product Features
1.The cabinets and partition boards adopting hotdip AI-Zn alloy-coated steel sheet and frame adopting multiple bending technology make highoverall intensity and good earth continuity.
2.Fully considering the operation characteristics of the neutral point of the power system without grounding or through the arc suppression coilgrounding, increase the insulation clearance and enhance the insulation level, so as to ensure that the switchgear meets the high requirements for theinsulation strength.
3.Completely metal clad and absolutely compartments separation.
4.The degrees of protection is IP4X, which effectively prevents the equipment from being invaded by sundries and insect pests.
5.Simple and effective mechanical block for five- preventions,preventing from mis-operating.
6.The movable handcart use sworm and worm wheel propelling mechanism. The same type of handcart can be interchanged completely, easy tooperate and maintain.
7.It can be installed away from the wall, which is more convenient for double sides maintenance. Or it can be installed against the wall, maintain in frontof the cabinet, with less space occupation.
8.Min. width of panel is 550mm, which can increase the utilization of distribution room.
9.The product runs safely and reliably through the harsh condensation, filth and internal arc tolerance test.
