Composite Insulator Inspection Before Use
- Jul 21, 2018 -

1. The products have been tested and sample tested according to the standards before leaving the factory. In order to prevent damage during transportation, they should be carefully examined one by one before installation. Insulators' surface defects (eg, lack of glue, depth of depression ≤1mm) are less than 0.2% of the total surface area of the insulator.


2. Do not use if the umbrella cover has tear or wear and the mandrel is exposed.
