Service conditions
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.
