It complies with the standards GB7251 Low-voltage switchgear assembly, JB/T9961 Low-voltage withdrawable switchgear assembly, and the international standards IEC60439 GB7251.1.

Service conditions

Ambient air temperature should be within - 5°C~ +40C, average temperature within 24h should not exceed +35C. Atmospheric conditions: air should be clean. Relative humidity should not exceed 50% at +40C, higher relative humidity is allowed at lower temperature condition, for instance, 90% at +20C,please take measures for the dew produced on the product caused by temperature changeoccasionally.

Altitude: not exceed 2000m.
Ambient temperature for storage and transportation: - 25C~+55C, short time (usually not beyond 24h) highest temperature not exceed 70C.
The product should not be subject to any irreversible damage under the extreme temperature and should be able to work normally under the normal conditions. Any special requirements beyond the abovementioned conditions can be settled through friendlynegotiation. We'd like to come to an agreement separately for the product intended for offshore oil drilling platforms and nuclear power stations.

                                                          Product Parameters

High/Low voltage switchgear quality control:

The manufacturing of high/low voltage switchgear needs to be carried out in strict accordance with national standards, and quality control is required.
In manufacture in the process, materials, components, assembly, welding, insulation treatment, electrical testing and commissioning are required quality control.
At the same time, it is also necessary to carry out inspection, testing and acceptance.
