The insulator tester under UHV power can help many power workers conduct various power tests more conveniently.

The main function of insulators is to achieve electrical insulation and mechanical fixation, and various electrical and mechanical performance requirements are specified.

If under the specified working voltage, there is no breakdown or flashover along the surface due to lightning overvoltage and internal overvoltage; No damage or destruction under specified long-term and short-term mechanical loads; Under the specified machine, there will be no significant deterioration after long-term operation under electrical load and various environmental conditions; The accessories of insulators will not produce significant corona discharge under working voltage to avoid interference with radio or television reception.

Due to the widespread use of insulators, it is also required that their connecting accessories have interchangeability. In addition, the technical standards for insulators also require various electrical, mechanical, physical, and environmental conditions to test the performance and quality of insulators according to different models and usage conditions.

Maintenance

1. Power outage cleaning

Power outage cleaning refers to workers climbing up power poles and wiping them with a cloth after the line is cut off. If it is not clean, it can be wiped with a damp cloth or cleaning agent. If it is still not clean, the insulator should be replaced or the composite insulator should be replaced.

2. Clean without losing power

Generally, insulation rods with brushes or cotton yarn are used to wipe the insulation on the running line. The electrical performance and effective length of the insulation rod used, as well as the distance between people and live parts, should meet the requirements of the corresponding voltage level, and must be supervised by a dedicated person during operation.

3. Rinse with charged water

There are two methods: large water flushing and small water flushing. The flushing water volume, effective length of the operating rod, and distance between people and live parts must comply with industry regulations.
