Description

Technical Field

[0001] The utility model relates to the field of cable installation, in particular to a pre-tightening device for power cable installation. Background Art

[0002] The installation of power cables is a critical step in power system construction. Their primary function is to transmit electricity from power plants to various power-consuming areas. Stable cable installation not only affects the safety and stability of power transmission but also the operational efficiency of the entire power grid. Precise installation and tension control of power cables are particularly important in scenarios such as urban power supply systems, factory power layouts, and high-voltage transmission lines. Laying power cables requires ensuring they maintain proper tension over long distances and in complex environments to prevent them from becoming too loose or too tight, which could affect transmission performance or cause damage.

[0003] Most existing pre-tensioning devices for cable installation adopt a fixed tension design, which cannot flexibly adjust the cable tension according to actual conditions. The limitations of this design make the device less adaptable to different working conditions or cable types. Especially in complex terrain or long-distance installation, the stress conditions of the cable may change with changes in environmental conditions. If the cable tension cannot be adjusted, the cable may be too loose in some areas, thereby increasing friction and wear, or too tight in other areas, causing the cable to be overstretched, damaged, or even broken.
