Tracking & Erosion tester is used for tests of silicon rubber shed and housing of electrical polymeric insulators. It is to test the anti-tracking and erosion ability of its silicon rubber material as per IEC or DIN EN standard.
- General Details
What is a tracking & Erosion testing machine?
The tracking & Erosion testing machine is a test machine for polymeric insulators. It is designed to inspect the anti-tracking and anti-erosion performance of HTV silicon rubber of the insulators. It provides the testing function of the tracking-erosion test of silicon rubber of high voltage composite insulators (polymer insulators).
With this machine, users can test the anti-tracking performance of the silicon rubber sample under the constant electrical current low and erosive liquid. Users may set the testing time length, current, and speed of flow and clearly observe the anti-tracking& erosion test procedure. There are glass observing windows. Users may witness the whole status of the test.
This test machine has 5 working loads, which means users can test up to 5 pieces of samples of silicon rubber at the same time.
The testing methods and acceptance criteria shall be subject to “9.3 Tests of shed and housing material” in IEC 62217-2012 “Polymeric insulators for indoor and outdoor use with a nominal voltage > 1000V – General definitions, test methods, and acceptance criteria”.
