Product Details

KYN28-12 Metal-Clad Enclosed High Voltage Switchgear Cabinet


Introduction:

KYN28-12 Metal-Clad Enclosed Switchgear Cabinet is used for the indoor complete power distribution device for 3.6KV~12KV, 3 phase AC 50/60Hz, rated current of 630~4000A.

It complies with GB/T11022, GB/T3906, DL/T404 and other relative standards. It has functions of preventing to push or pull the breaker’s handcart with load, breaker’s mistakenly open or close, shut off the breaker when the grounding switch is on the positon 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, it can be used with VD4 from ABB and EV12S from Schneider.

Features

●The cabinets and partition boards adopting Al-Zn alloy coated steel plates and frame adopting multiple bending technology make high overall intensity and good earth continuity.

The door is plastic sprayed to ensure the high impact resistance and corrosion resistance ability as well as high mechanical strength

Completely metal clad and absolutely compartments separation.

The protection level is IP4X, which effectively prevents the equipment from being invaded by sundries and insect pests

Simple and effective mechanical block for five-preventions, preventing from misoperation.

The movable handcart use sworm and worm wheel propelling mechanism. The same type of handcart can be interchanged completely, easy to operate and maintain.

The cabinet can be installed against the wall, which is more convenient for double sides maintenance. Or it can be installed against the wall, maintain in front of the cabinet, with less space occupation.

Min. width of panel is 550mm, which can increase the utilization of distribution room.
