Zinc thickness test device
Zinc thickness test device is a test equipment for zinc coating thickness of metallic fitting of high voltage insulators.
This test device is portable, very light and convenient to carry for engineers to inspect insulator accessories on site.
Zinc coating thickness test is a very important test in IEC standard for composite insulators, ceramic insulators and glass insulators of high voltage over 1000V. It’s vital because insulators applied on overhead power transmission line may suffer erosion in natural environment, thus sufficient thickness may keep running safety of insulators.
