GCS Low-voltage withdrawable switchgear
Product description
GCS devices are suitable for power distribution systems in power
plants, petroleum, chemical, metallurgy, textile, high-rise
buildings and other industries. In large-scale power plants,
petrochemical systems and other places with a high degree of
automation and computer interfaces, it is used as a three-phase AC
frequency of 50 (60) Hz, rated working voltage of 380V (400V,
660V), and rated current of 4000A and below. , Low-voltage complete
set of power distribution equipment used in power distribution,
centralized motor control and reactive power compensation in the
power supply system
Model and its meaning
①AC enclosed low-voltage switch cabinet
②Withdrawal
③Electrical system
④Main circuit plan number
⑤ Number of auxiliary circuit scheme
Conditions of Use
• The ambient air temperature is not higher than +40°C and not
lower than -5°Co. When the average temperature within 24 hours must
not exceed +35°Co, it needs to be derated according to the actual
situation.
• For indoor use, the altitude of the place of use must not exceed
2000m.
• The relative humidity of the surrounding air does not exceed 50%
when the highest temperature is +40°C, and a larger relative
humidity is allowed at lower temperatures, such as 90% at +20°C,
and the possibility of temperature changes should be considered
Will have the effect of condensation.
• When the device is installed, the inclination to the vertical
surface does not exceed 50°C, and the entire group of cabinets is
relatively flat (in accordance with the GBJ232-82 standard).
• The device should be installed in a place where there is no
violent vibration and impact and not enough to prevent the
electrical components from corroding.
