Inspection before use high voltage insulator is important
- May 21, 2018 -

High voltage insulator are produced using an integral injection molding process. Sheds sleeve is beautiful in appearance, with few interfaces, and the mandrel and jacket are firmly bonded with no gaps. The inner insulation performance is good, and the interface breakdown phenomenon can be avoided.

1.The products have been tested and sample tested according to the standards before leaving the factory. To prevent damage during transportation, they should be checked carefully 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 sheds cover has tear or wear and the mandrel is exposed.

So, high voltage insulator should be inspection carefully before safety use.
