GCS low-voltage withdrawable type complete switchgear (hereinafter referred to as the "switch
equipment") is my company to meet the requirements of the design unit and power users design developed in line with the national conditions, with high technical performance indicators and can adapt to power market development needs and can compete with the introduction of existing product low voltage draw-out switchgear.
This product has been widely used by power users.
Switchgear is suitable for power plant, petroleum, chemical, metallurgy, textile, high-rise building and other industries
distribution system.
In large power plants, petrochemical systems and other places with high degree of automation and requiring computer interface, itis used as a low-voltage complete power distribution device for power distribution, centralized control of motors and reactive power compensation in power generation and power supply systems with three-phase AC frequency of 50(60)Hz, rated working voltage of 380V(400V), (660V) and rated current of 4000A or below.
The basic form of switchgear (see figure 1).
This product conforms to the standards of GB7251 low voltage switchgear and control equipment, JB/T9661 low voltage draw-off switchgear and IEC439 low voltage switchgear and control equipment.

1.Temperature of ambient air: -5°C~+40 pairs;The average daily temperature shall not be higher than +35°C.
In case of excess, the capacity shall be reduced according to the actual situation.
2.Altitude: 2000m and below.
3.relative humidity: the maximum temperature of +40P is not more than 50%, at a lower temperature allowed to have a large relative humidity: such as +20P is 90%, should take into account the temperature changes may occasionally produce the impact of condensation.
4.The mounting incline shall not exceed5.and the whole group of cabinets is relatively flat (in line with GBJ232-82 standard).
5.Switchgear should be installed in places free from severe vibration and shock and not enough to cause undue corrosion ofelectrical components.
Note: users have special requirements, can negotiate with the company to solve.
