Product details
Product overview
GCS type low-voltage draw-out switchgear is suitable for power distribution systems in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with high degree of automation and computer interface requirements, it is used as a low-voltage complete power distribution device for power distribution, centralized motor control and reactive power compensation in power generation and supply systems with three-phase AC frequency of 50(60)Hz, rated working voltages of 400V and 660V and rated current of 5000A or less.
The design of the device conforms to the following standards: IEC439-1 《Low Voltage Complete Switchgear and Control Equipment》 GB7251 《Low Voltage Complete Switchgear》.
Normal operating environment
◇ Ambient air temperature shall not be higher than +40℃ , not lower than-5℃ , and the average temperature within 24 hours shall not be higher than
+35℃ . In case of exceeding, the capacity shall be reduced according to the actual situation.
◇ For indoor use, the altitude of the place of use shall not exceed 2000 m;
◇ The relative humidity of the ambient air shall not exceed 50% at the highest temperature of +40℃ , and relatively high relative humidity is allowed at lower temperature, such as 90% at +20℃ , which shall be considered Due to changes in temperature, condensation may occasionally occur.
◇ When the device is installed, the inclination to the vertical plane shall not exceed 5, and the whole set of cabinet columns shall be relatively flat (in line with GBJ232-82 standard);
◇ The device shall be installed in a place free from severe vibration and impact and insufficient to expose electrical components to corrosion.
◇ When users have special requirements, they can negotiate with the manufacturer.
