Purpose

GCS type low-voltage withdrawable switchgear is suitable for distribution systems in industries such as power plants, petroleum, chemical, metallurgical, textile, and high-rise buildings. In places with high automation levels such as large power plants and petrochemical systems that require computer inteLXaces, low-voltage complete distribution equipment is used for distribution, centralized control of motors, and reactive power compensation in power generation and supply systems with three-phase AC frequency of 50 (60) Hz, rated working voltage of 400V, 660V, and rated current of 5000A and below.

The design of the device complies with the following standards: IEC439-1 Low Voltage Switchgear and Control Equipment GB7251 Low Voltage Switchgear.

Normal Usage Conditions

The ambient air temperature shall not exceed+40 ℃ , not be lower than -5 ℃ , and the average temperature within 24 hours shall not exceed+35 ℃ . When exceeding the limit, it is necessary to reduce the capacity and operate according to the actual situation;

For indoor use, the altitude of the place of use shall not exceed 2000m;

The relative humidity of the surrounding air should not exceed 50% at the highest temperature of+40 ℃ . A relatively high relative humidity is allowed at lower temperatures, such as 90% at+20 ℃ . It should be considered that condensation may occur accidentally due to temperature changes;

When installing the device, the inclination with respect to the vertical plane shall not exceed 5 °, and the entire cabinet column shall be relatively flat (in accordance with GBJ232-82 standard);

The device should be installed in a place without severe vibration and impact, as well as in a place where electrical components are not corroded as they should be;

When users have special requirements, they can negotiate with the manufacturer to solve them.
