GCS low voltage withdrawable switch cabinet

Short Description:

ProductCategory: Low Voltage Switchgear Series

Intro: GCS type low voltage withdrawable switchgear is 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 400V, 660V, and rated current of 5000A and below. Low-voltage complete set of power distribution equipment used in power distribution, centralized motor control, and reactive power compensation.

GCS Use environmental conditions

♦ The ambient air temperature is not higher than +40℃, not lower than -5℃, and the average temperature within 24 hours must not be higher than +35℃. When it exceeds, 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 maximum temperature is +40°C, and a larger relative humidity is allowed at lower temperatures, such as 90% at +20°C. It should be considered that accidents may occur due to temperature changes The effect of condensation;

♦ When the device is installed, the inclination from the vertical plane does not exceed 5°, and the entire group of cabinet rows is relatively flat (in line with GBJ232-82 standard);

♦ The device should be installed in a place where there is no severe vibration and shock, and it is not enough to subject the electrical components to no corrosion;

♦ When the user has special requirements, he can negotiate with the manufacturer to solve it.
