China Manufacturers Supply High Quality Outdoor Electric Power
Distribution Box Low Voltage Switchgear
GCS type AC low-voltage distribution switchgear is used in power
distribution system 50Hz, rated working voltage 380V and rated
current up to 3150A as power conversion, distribution and control
of power, lighting and distribution equipment, suitable for power
users such as power plants, substations, industrial and mining
enterprises.
GCS LV switchgear has high breaking capability, good dynamic
thermal stability, flexible electrical scheme, flexible
combination, complete series, strong practicability, novel
structure and high protection degree. It is a good product for
replacement and upgrading of complete LV switchgear assembly.
Features
GCS withdrawable switchgear is a low-voltage complete power
distribution device ,suitable to AC 50-60Hz, rated
working voltage of 660V or below, rated current of 4000A and below,
power distribution, motor centralized control,
power factor correction.
GCS withdrawable switchgear is used as a substation, feed or motor
for low-voltage distribution systems of 3P-3W or
3P-4W. GCS withdrawable switchgear has increased its capacity and
mechanical strength on the basis of maintaining higher electrical
performance, and has characteristics of advanced structure, perfect
appearance, high protection level, safety and reliability, and easy
maintenance.

than others.
Our main market covers medium voltage, high voltage and ultra-high
voltage power distribution.
Working Environment
1. Indoor altitude above sea level: Maximum installation altitude:
2000m
2. Ambient air temperature: -5℃~+40℃ and the average temperature
should not
exceed +35℃ in 24h
3. Relative humidity should not exceed 50% at max temperature +40℃.
Higher
relative humidity is allowed at lower temperature. Ex. 90% at +20℃.
But in view of
the temperature change, it is possible that moderate dews will
produce casually.
