KYN61-40.5 铠装移开式金属封闭开关设备
KYN61-40.5 armour open type metal enclosed switch cubicle
General:
The device is mainly used in 40.5KV three phase AC 50HZ single bus and section
system complete power distribution device. The main insulation uses compound
insulation design. It can equipped with ZN85, VTK circuit breaker and VD4 made by
ABB, and mainly used in power station, substation, and industrial mining enterprise
to control and protect.
The main characteristics:
1. The shell of cubicle uses the aluminum zinc plate, and has the function of
anti-oxidant, resistant to corrosion; uses Compositional type and is connected by
riveting screw and bolt.
2. The handcart of circuit breakers uses floor type structure with easy movement.
3. The bus uses pyrocondensation insulation materials and epoxy paint design,
which optimizes distribution of electrode, makes compact structure.

KGN 口-12 铠装移开式金属封闭开关设备
KGN 口-12 armour open type metal enclosed switch cubicle
General:
The device is mainly used in 3.6-12kv three-phase AC 50HZ single bus and section
system complete power distribution device. The device equipped with vacuum circuit
breaker can be used in power station, substation, and industrial mining enterprise and
so on.
The main characteristics:
The shell of cubicle uses the aluminum zinc plate, and has the function of
anti-oxidant, resistant to corrosion; uses Compositional type and is connected by
riveting screw and bolt.
