Why Is It Necessary To Regularly Inspect And Maintain Power Fittings?

As operating time increases, aerial electrical fitting may be affected by environmental corrosion, mechanical fatigue, electrical erosion, etc. These problems are often invisible but will appear during load fluctuations or severe weather, posing potential risks to the overall line.

Regular inspections not only target the surface condition of components power line hardware but also include assessments of mechanical properties, electrical continuity, and tightness. Professional inspectors use techniques such as thermal imaging and tensile testing to evaluate potential loosening, cracks, and poor contact, identifying defects that are not easily visible to the naked eye.

Maintenance personnel will clean, adjust, or replace worn parts on the overhead line fittings, which helps maintain connection stability and overall line reliability. distribution line hardware is located in a high-pressure and outdoor environment, and is affected by temperature changes, wind and rain erosion, etc. If small problems are not dealt with in the early stages, they will accumulate over time and affect the operating performance. Regular inspections and maintenance can intervene in these accumulated problems, extending the service life of components.
