Raising Testing Standards For Power Fittings: Contributing To The Improvement Of Power Fitting Quality.

Upgrading the distribution line hardware testing standard was promoted, and the overhead line connectors testing content was expanded to include multiple indicators such as mechanical performance testing, material composition analysis, dimensional accuracy, and appearance inspection.

Mechanical performance testing covers key items such as tensile force, fatigue, and breaking load of overhead line hardware, while material composition analysis covers the content and alloy ratio of metals such as copper, aluminum, and steel.

Dimensional and appearance inspection involves rigorous measurement and recording of geometric dimensions, geometric tolerances, surface cracks, burrs, oxidation, and other defects.

The overhead power line connectors testing report was compared with the production batch to verify consistency between raw materials, manufacturing batch number, structure, and the report.
