Product details
Product overview
GGD type AC low voltage distribution cabinet is suitable for power distribution systems with 50Hz AC, 380V rated working voltage and 5000A rated working current for power plants, substations, industrial and mining enterprises and other power users. it is used for power conversion, distribution and control of power, lighting and distribution equipment.
The product has the characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, strong practicability, novel structure, high protection level, etc. It can be used as a replacement for low-voltage switchgear.
GGD type AC low-voltage power distribution cabinet complies with IEC439 《low-voltage complete switchgear and control equipment》 and GB7251 《low-voltage complete switchgear》 and other standards.
Normal operating environment
◇ Ambient air temperature is not higher than +40℃ and not lower than -5℃ . The average temperature within 24 hours shall not be higher than+35℃ .
◇ For indoor installation and use, the altitude of the place of use shall not exceed 2000m m.
◇ The relative humidity of ambient air shall not exceed 50% at the highest temperature of +40℃ , and a larger relative humidity is allowed at the lower temperature. (for example, 90% at +20℃ ) consideration should be given to the effect that condensation may occasionally occur due to temperature changes.
◇ When the equipment is installed, the inclination to the vertical plane shall not exceed 5.
◇ The equipment shall be installed in places free from severe vibration and impact, and places insufficient to corrode electrical components.
◇ When users have special requirements, negotiate with the manufacturer to solve them.
