[0002] Phase-line composite cables integrate conductors with different functions, such as power, communication, signal, and grounding, into one sheath to form a multifunctional cable structure. When using phase-line composite cables, they need to be installed on a cable rack using an installation device.

[0003] When the existing phase-line composite cable is installed on the cable, due to the heavy weight of the cable, it is too time-consuming and labor-intensive for the worker to pull the cable to release it, resulting in the cable being pulled and released too slowly, leading to low cable installation efficiency. In addition, during the process of pulling the cable to release it, if the cable is pulled too much to release it, it will cause excessive bending between the cable and the reel, which can easily cause the cable to break and be damaged, affecting the normal use of the cable.
