Product Description

Medium Pressure Chamber for Factory Building KYN28 Armoured Removable

Switchgear Metal-Clad Indoor AC Metal-Enclosed Switchgear:



♦ KYN28-12 Steel-clad Movable-type Alternating-current Metal-enclosed Switchgear is packeged

all metal modularization structure. The cabinet use the imported AI-Zn-plated steel sheet with

high corrosion resistant capacity and needn't surface treatment.By CNC precision processing

equipment, advanced multiple flanging process and connection with riveting nut, high strength bolt,

it has features of high precision, light weight and good strength.


♦ The switchgear suitable for the vacuum circuit breakers like ZN63(VS1)-12 series,VD4 series,

ZN65 series,etc.It has wide adaptability and strong interchangeability.Handcart is equipped with the

work location and test position. Each position has positioning and display device.It is safe and reliable.

The cable chamber can be up to 9single core cable installation. It has reliable mechanical and electrical

interlocking device. ♦ The safety meet the requirement of " five prevention".

Each room is equipped with pressure relief channel,encure running safety.

Service environment

1. Ambient air temperature: -5ºC+40ºCand the average temperature should not exceed +35ºC in 24h.

2. Air condition: With clean air. Relative humidity should not exceed 50% at +40ºC. Higher relative

humidity is allowed at lower temperature. Ex. 90% at +20ºC. But in view of the temperature change,

it is possible that moderate dews will produce casually.

3. Altitude above sea level should not exceed 2000M.

4. The device is suitable to the transportation and store with following temperature:-25ºC ~+55ºC,

in short time (within 24h) it reaches +70ºC. Under the limiting temperature, device should not suffer

damage that can[1]t recover, and it can works normally under normal conditions.

5. If the above operating conditions not meet user's demand. Consult with manufactory.

6. Technical agreement should be signed additionally if the device is used for marine petrol drill

taken platform and nuclear power station.
