Technological Innovation In Power Fittings Testing

Traditional overhead power line connectors inspection methods have long relied on manual visual observation and handheld device measurement. In the overhead power line hardware production process, inspectors need to verify the dimensional accuracy, surface quality, and mechanical strength of each transmission line hardware piece one by one. This method is limited by differences in personnel experience, visual fatigue, and insufficient precision of measuring tools, resulting in data fluctuations ranging from ±2°C to ±5°C, which is insufficient to meet the stringent requirements of power transmission systems for connecting components.

Modern industrial-grade testing equipment has reduced the measurement error of electrical transmission line hardware fittings to within ±0.5℃. An automated system equipped with high-precision sensors can perform a full-dimensional scan of the tensile strength, electrical conductivity, and corrosion resistance of hardware fittings for transmission lines. The testing process uses a preset algorithm to compare the technical parameters of national standard GB/T 2314 and industry standard DL/T 768 in real time. Machine vision technology can capture microcracks as small as 0.1 mm that are invisible to the naked eye. Digital reports generated by specialized equipment such as tensile testing machines and salt spray chambers replace manual recording, achieving 100% data traceability.
