As a professional high voltage insulator supplier, the quality of our insulators are the critical important thing to us. So Orient Power focus on the quality and the electrical properties of the insulators, we do all kinds of tests to guarantee the electrical properties of the high voltage insulator, such as the Routine tests for high voltage composite insulator, the sample tests for high voltage composite suspension insulator, and so on.

The introduction of the routine tests for high voltage composite suspension insulator:
The routine tests for high voltage composite suspension insulator include the two parts: electrical tests and mechanical tests.

The mechanical tests of the high voltage composite suspension insulator:
Prior to or simultaneous with the final electrical test, the composite suspension insulators shall be given a tensile-strength test 3 seconds in duration, at specified value, applied in line with the axis of the insulator. The routine tests for high voltage composite suspension insulator is just one kind of test of Orient Power, and the composite suspension insulator is just one kind of high voltage insulator of Orient Power.
