How to Extend the Life of Your Overhead Power Line Insulators

Material selection optimization

Use high-quality insulation materials, such as rubber or polymer, for better weather and corrosion resistance. When using down lead clamps, parallel groove clamps are made of rubber that is resistant to aging.

Regular testing

Perform regular insulator inspection and maintenance, including visual inspections and electrical tests, to detect potential problems in a timely manner. The insulator tie used for optical cables is often overlooked due to its high position.

Cleaning and maintenance

Regularly clean dirt and accumulation on the surface of insulators, especially in heavily polluted areas, to prevent leakage and breakdown. The Bird flight diverter is not easy to clean when used at high altitudes, so regular replacement is the best option.

Proper installation

Ensure that insulators comply with design specifications when installed to avoid stress concentration and damage caused by improper installation.

Use antifouling measures

In heavily polluted areas, consider using antifouling coatings or specially designed insulators to reduce the impact of dirt on insulation performance.
