This series of low-voltage draw-out switchgear is a combination of factory-assembled (FBA) cabinet with standard modules, and its technology has reached the international advanced level.
This series of low-voltage draw-out switchgear is suitable for power plants, substations, petrochemical industry, gold and steel rolling, transportation energy, light industry textile and other factories and mining enterprises and residential areas, high-rise buildings and other places, as AC 50~60hz, rated working voltage AC 660V and below the power system of power conversion, distribution and control.
The device conforms to the national professional standards of GB72511 "Low-voltage Switchgear Assembly" and JB/T9961 "Low-voltage withdrawing-type switchgear Assembly", and complies with international professional standards such as IEC439-1, VDE0660 Part V and so on.
1.The ambient temperature is not higher than +40 ° C, not lower than -5 ° C, and the average temperature within 24 hours is not higher than +35 ° C.
2. Atmospheric conditions, clean air, the relative temperature at the highest temperature of +40℃ does not exceed 50%, at lower temperatures allow a higher relative wet hundreds of sizes V brake long wind power, such as +20℃ is 90%, but should take into account the temperature change, there may be occasional moderate condensation.
3. The altitude does not exceed 2000m.
4. The device is suitable for transport and storage at the following temperatures: between -25 ° C and +55 ° C, within a short period of time (not more than 24h) up to +70 ° C, at these limit temperatures the device should not suffer any irreparable damage, and should be able to work normally under normal conditions.
5. If the above requirements cannot be met, it shall be resolved by negotiation between the user and the manufacturer
