MV KYN28B-12 Metal-clad Movable Switchgear for Circuit Control,
Protection and Monitor
MV KYN28B-12 metal-clad movable switchgear.
MV KYN28B-12 metal-clad movable switchgear is suitable for complete indoor power distribution systems of
three-phase, AC, 50 Hz and 12 kV rated voltage. It is used to
receive and distribute power energy, and it is also used to
control, protect and monitor circuits. This kind of switchgears are
widely used for power plants, transformer substations, airports,
railways, subways, supermarkets, shopping centers and hospitals.
They are also used for industries, such as paper-making, cement,
textile, chemical engineering, food, automobile, metallurgy and
MV KYN28B-12 metal-clad movable switchgear is the modification of
MV KYN28A-12 metal-clad movable switchgear, so it not only has the
advantages of MV KYN28A-12 metal-clad movable switchgear, but it
also has other features which are shown below.
- The depth of switchgear is 1200 mm, which is similar to the depth
of existing XGN and GG-1A switchgears designed by China. And the
installation basements of the two switchgears are completely same.
- The height of switchgear is 2200 mm, and this height is coincident
to complete low voltage equipment. And it is very suitable for the
design of box transformer substations.
- Pressure relief cover is designed of heat dissipation function,
which is beneficial to in-time ventilation & heat dissipation.
This design can also prevent dust effectively.
- Small bus-bar terminal and small bus-bar are our patented products,
and their installation and overhaul are simple and convenient.
Normal working conditions:
- Temperature range: -25 °C to +40 °C.
- The maximum daily average relative humidity: 95%.
- The maximum monthly average relative humidity: 90%.
- Altitude1000 m.
- Seismic intensity8 degree.
Note: if the working condition is beyond the normal working conditions,
please contact us before goods ordering.
Special matters needing attention:
The temperature of many regions in our country is high, and
temperature fluctuation is fast, so switchgears are faced with the
risk of condensation running in this kind of environment.
Therefore, there are some matters needing attention in switchgears
- Heaters should be put into operation as early as possible after
switchgears are installed.
- Ensure heaters at running condition all day during switchgears
standing by and running.
