HV insulator testing

As we can know, each product has its own production specification, A series of tests are conducted by them before leaving the factory, In order to ensure the quality of products. High voltage insulator is no exception, now let us to know the HV insulator testing.

HV insulator testing

The composite HV insulator including mainly including three parts: silicone rubber sheds, fiberglassrod, and highgradesteel endfittings.

The composite HV insulator testing:
1. Raw material test
◆Silicone rubber:
Tensile test
Tracking and erosion test
◆Fiber glass rod:
Tensile failing
Dye penetration test
◆End fittings:
Galvanizing test
Gauging test
Mechanical failing load test
Dimensional test

2. On composite insulators:
◆Routine test:
Appearance inspection,
Power frequency withstand test
Routine mechanical test
◆Sample test:
Dimensional inspection,
Mechanical failing load test
Dye penetration sealing test

3. Other tests on composite insulators:
◆Power frequency flashover dry and wet
◆Power frequency withstand dry and wet
◆Lightning impulse flashover dry and wet
◆Lightning impulse withstand dry and wet

HV insulator testing is important for us to know the insulators, we can offers the insulator after rigorous testing, you can rest assured purchase
