GCS switchgear is suitable for power supply and distribution
systems with AC 50Hz, rated working voltage 690V or less and rated
current of main bus up to 4000A. The product adopts 8MF open
section steel, which makes the frame assembly flexible and
convenient, and can form standard units such as protection,
operation, conversion, control, regulation, measurement and
indication. The maximum number of functional units of a single
drawer cabinet can be up to 22, which fully takes into account the
need of centralized control of motors in large single capacity
power plants, petrochemical systems and other industries. The
specific heat capacity of the adapter is high, which reduces the
additional temperature rise caused by the temperature rise of the
adapter to the connectors, cables and partitions. The parallel
arrangement of buses makes the equipment have good dynamic and
thermal stability, can withstand large short-circuit current
impact, and has the characteristics of high insulation strength,
good self-extinguishing performance, unique structure and strong
adaptability to the bus. The corresponding protection level can be
selected according to the different requirements of the working
environment.

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.
4. No fire, explosion danger, serious pollution, chemical corrosion
and severe vibration
5. Installation gradient not exceed 5°
6. This product is suitable for the following temperature
transportation storage: -25℃ ~+55℃ 24h, in a short period of time (no more than 24hours) not more than+70℃.
