HMNS low-voltage draw-out switchgear is a new generation of low-voltage switchgear developed by huanghua group co., LTD according to the market demand.Product technical standards meet IEC439 "low-voltage complete switch equipment and control equipment", GB7251 "low-voltage complete switch equipment" and other standard requirements.
HMNS low-voltage extractor switchgear is suitable for power conversion, distribution and control of power distribution equipment in power system with rated working voltage of 660V and below, which is used in power plants, substations, petrochemical, metallurgical, steel rolling, light industrial and textile enterprises, residential areas, high-rise buildings and other places.
Ambient air temperature is not higher than +40℃, not lower than 5℃, and its average temperature within 24h is not higher than +35℃;
Atmospheric conditions: clean air, phase zhou humidity in the highest temperature for +40℃ not more than 50%, in the lower temperature allowed to have a higher relative humidity, such as +20℃ for 90%, but should consider the temperature change, may occasionally produce condensation;
Altitude less than 2000m;
The device is suitable for transportation and storage at the following temperature: 25℃ to +55℃ range.It can reach +70℃ for a short time (no more than 24h). The device shall not suffer any unrecoverable damage at these limiting temperatures and shall work normally under the above conditions.
Delta if the above use conditions cannot be met, should be negotiated by the user and the manufacturer to resolve;
Additional technical agreements are required for use on offshore oil drilling platforms and nuclear power plants.
