Wet process porcelain pin insulator test
Every batch of wet process porcelain pin type insulator must go through different tests. About pin insulator test, design tests shall be required only on insulators of new designs. Quality conformance tests shall be required on some insulators of every batch. And routine tests shall be made on every insulator.
Design tests for Wet process porcelain pin insulator:
Design tests are very important for pin type insulator. According to ANSI C29.1 test methods, there are low-frequency dry flashover test, low-frequency wet flashover test, critical impulse flashover tests-positive and negative, radio-influence voltage text and thermal shock text.
Quality conformance tests for Wet process porcelain pin insulator:
Quality conformance tests main characteristics electrification of pin insulator, so, quality conformance tests is the test to inspect the quality of pin insulator. Quality conformance tests include visual and dimensional tests, porosity test, cantilever-strength test, pinhole gaging test and puncture test.
Routine test for Wet process porcelain pin insulator:
Routine test also known as flashover test for pin insulator, It is the most demanding test of pin insulator. Routine test require each pin insulator shall be subjected to a routine flashover test.
Product quality is our top concern and we will be careful examination for every produced high voltage insulator. We are looking forward to your e-mail us.
