It Is Necessary To Strengthen The Professional Testing Of Power Fittings.

With the continuous expansion of transmission lines and distribution networks, the reliability requirements for power system connectors are becoming increasingly stringent. As an important component connecting overhead lines, towers, and insulators, the physical properties and structural condition of component overhead line fittings have a direct impact on the stability of the overall system.

When conducting testing, appropriate testing methods should be used for different types of distribution line hardware. Physical performance tests include tensile strength, compressive strength, corrosion resistance, and weather resistance, applicable to metal connectors, mounting plates, and supports. For components potentially exhibiting cracks, weld defects, or material fatigue, ultrasonic testing or phased-array ultrasonic scanning equipment can be used to detect hidden problems such as internal cracks, poor welds, or microcracks.
