The quality of raw materials has a great impact on the insulation performance of insulators.
Therefore, the selection of raw material manufacturers is particularly important. We should not blindly reduce costs and lose the quality of materials. We should choose materials from reputable manufacturers For each batch of incoming materials, the batch number, material certificate and other important information shall be carefully checked, and the traceability data of material use shall be well prepared.
Inspection of insulation resistance of insulator:
At present, some manufacturers require to test the electrical performance after assembling into finished products. As a result, the insulation resistance of the insulator itself is unqualified, so the whole batch of finished products have to be scrapped. The reasonable process should be 100% process screening in the state of insulator parts to ensure that the electrical performance is qualified.
