The Performance Of Power Fittings During Long-term Operation Is The True Basis For Verifying Their Quality And Performance.

In actual projects, operational data of aerial electrical fitting under long-term load, environmental corrosion and seasonal temperature difference should be collected regularly, and the data related to power line hardware should be compared and analyzed with the original design parameters. Data from real-world operating environments often provides a better reflection of the overall performance of materials and manufacturing processes than short-term experimental tests.

For overhead line fittings, mechanical load testing, electrical performance testing, and corrosion resistance evaluation are the testing methods commonly used in the distribution line hardware industry. These testing elements are subject to specific standards for inspection before production, after production, and during the commissioning phase. Typical breaking load tests are used to measure the tensile strength of connected components under extreme conditions, while electrical performance testing focuses on parameters such as contact resistance and thermal stability. By cascading multiple test results, a performance profile of the product under various operating conditions can be gradually established.
