Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a towable cable. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the trunk lines of power systems, including 1, 500KV and above various voltage levels, various insulated power cables, among which the "a cable" disclosed by the announcement number "CN213339755U" has solved the problem that the cables on the market are currently subjected to uneven force when subjected to external pressure, and the forces between the core wires will affect each other, resulting in some core wires being compressed while other core wires are compressed at the same time, resulting in poor compression resistance of the overall cable, resulting in reduced cable transmission power, so the cable is easily damaged by external force squeezing, affecting the service life of the cable. After further searching, it was found that the public The "a cable" disclosed by the notification number "CN203799709U" has effectively solved the problem of relatively simple performance of existing cables through specific technical structure settings. For example, some cables are relatively resistant to high temperatures, but have poor electromagnetic compatibility and poor pressure resistance, etc. However, in actual use, cables with similar structures still have many defects. For example, most of the towable cables on the market currently simply use insulating materials to extrude and install the wire core. This type of power cable has a very large safety hazard, and because of its simple structure and single material, the cable is often damaged, so it is necessary to design a towable cable.
