【 摘 要 】

In this paper, according to the "three-span" anchor clamp crimping quality inspection work plan and the statistical data of the overhead data transmission line, the quality problems of the anchor clamp crimping are summarized and the corrective measures are proposed. In order to compare the non-destructive testing effect of the "three-span" anchor clamp crimping quality of the transmission line and the influence of the crimping defects on the mechanical properties, the contrast test between the radiation detection and the ultrasonic inspection was also carried out. The test shows that the radiographic imaging can clearly show the internal defects of the crimping in the radiographic inspection, and the ultrasonic thickness measurement can quickly identify the defects.
