Why Has The Testing Of Electrical Fittings Relied On Manual Labor For So Long?

In many power transmission and distribution operation and maintenance practices, the status judgment of overhead power line connectors is still determined by on-site personnel through observation and recording. This detection mode has a long history, and most power companies continue to use this method in their daily inspection tasks. This is mainly because overhead power line hardware lines are distributed over a wide area of overhead lines, involving various physical forms and installation environments, requiring inspection personnel to identify abnormalities based on experience.

Traditional manual operation procedures typically involve an inspection team walking along the route to visually inspect the surface condition and fastening status of the transmission line hardware. This electrical transmission line hardware fittings inspection method relies on human perspective and judgment standards, which is limited in terms of coverage and frequency. On long-span, high-altitude, and complex terrain sections of the line, the inspection work of the hardware fittings for transmission lines line adds to the difficulty of hiking and climbing, and increases the labor intensity of on-site execution.
