[0002] With the continuous expansion of the scale of China's power industry, data communication industry, urban rail transit industry, automotive industry, shipbuilding industry and other industries, the demand for wire and cable will also increase rapidly. In the future, the wire and cable industry still has huge development potential.

[0003] However, in the existing technology, the current cable positioning device is relatively simple, and the positioning device cannot quickly and stably position the cable. Before transmission, the cable needs to be firmly installed on the mounting rack. However, the traditional positioning and installation device can only install and position cables with fixed sizes and cannot adjust the cable installation and positioning device according to the size of the cable.

[0004] Therefore, we need a cable terminal positioning device in a medium-voltage power transmission system to solve the problem of installing and positioning cables of different existing sizes, and can also adjust the cable installation and positioning device according to the size of the cable when installing and positioning the cable.
