Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a super-bending-resistant watertight cable. Background Art

[0002] Super-bending watertight cable is a special cable with the characteristics of bending resistance, water pressure resistance, anti-interference, high temperature resistance, excellent safety performance and high reliability. It is suitable for occasions with more complex bends and higher requirements on cable performance, such as underwater, high temperature, high pressure and other environments.

[0003] During the bending process of existing ultra-bending watertight cables, external forces act on the cables, causing the conductors, insulation layers and other materials inside the cables to be squeezed and stretched to varying degrees. Long-term bending can easily lead to fatigue damage of the cable materials, and ultra-bending watertight cables usually adopt a sealing structure to ensure the waterproof performance of the cables. However, this sealing structure will make the heat dissipation effect inside the cable worse, causing the temperature of the cable to rise during use, thereby affecting the performance and life of the cable.
