Plug-in Load Center Drawout (GGD Low Voltage) Electrical Distribution Cabinets
Product Description Product description
This series of low-voltage withdrawable switchgear for power plants, substations, petrochemical, metallurgical rolling, traffic energy, light industry and textile and other factories and mines and residential quarters, high-rise buildings and other places, as the exchange of 50? 60HZ, rated voltage AC 660V and The following power system power distribution equipment for power conversion, distribution and control purposes. Its technology has reached the international level.
This device complies with GE57251.1 "low voltage switchgear" and IB / T9961 "low voltage withdrawable switchgear" national professional standards, and in line with IEC439-1, VDE066 and other five professional standards.
Use environmental conditions
1. The ambient air temperature is not higher than +40 ° C, not less than -5 ° C, and the average temperature within 24H is not higher than + 35 ° C.
2. Atmospheric conditions: air clean, relative humidity at a maximum temperature of +40 ° C when not more than 50%, at low temperatures allow a higher relative humidity, for example: + 20 ° C when 90%, but should Taking into account the temperature changes, there may be occasional moderate cream.
3. Altitude does not exceed 2000m,
4. Pollution level 3.
5. This unit is suitable for the following temperature transport and storage processes: within a range of -25 ° C + 55 ° C, up to + 70 ° C in a short period of time (no more than 24H), at which the device should not be subjected to any Irreversible damage, and under normal conditions should be able to work properly.
Note: (1) If the above conditions of use can not be met, the user and the manufacturer should be resolved through consultation.
(2) When the device is used in offshore oil and cobalt mining platform and nuclear power plant, a separate technical agreement should be signed.
