AI Technical Summary
Existing cables are difficult to meet waterproof performance requirements, as moisture can easily penetrate the interior, affecting their service life. Furthermore, their torsional and tensile strengths are weak, making them prone to breakage under high tensile forces.
The waterproof aluminum alloy power cable is designed with a combination of wear-resistant layer, armor layer, outer waterproof layer, outer shielding layer, filling layer, central skeleton, metal reinforcing ribs and tensile rope. The outer waterproof layer is composed of metal composite tape and high-density polyethylene layer. The inner and outer waterproof layers enhance the waterproof capability, and the central skeleton and metal reinforcing ribs improve the overall strength.
It significantly improves the cable's waterproof performance and overall strength, preventing damage to the cable under bending or tension and extending its service life.

Abstract
Description
Technical Field
[0001] This application relates to the field of waterproof power cable technology, and in particular to a waterproof aluminum alloy power cable. Background Technology
[0002] Power cables are cables used to transmit and distribute electrical energy. Waterproof power cables are cables that can be used for a long time in places that are frequently submerged in water or damp. Waterproof power cables can be used underwater for a long time, preventing water from entering the cable and preventing cable failure, ensuring long-term stable operation of the cable underwater.
[0003] Existing cables are insufficient to meet people's requirements for waterproof performance. Moisture can enter the inside of the cable, ultimately affecting its use. In addition, existing cables have weak torsional and tensile strength. When the cable is subjected to large tensile forces, the cable core may be broken, affecting the overall service life of the cable.

Multiple cable cores are arranged around the outside of the metal reinforcing ribs. An insulation layer and an inner waterproof layer are arranged sequentially on the outside of the multiple cable cores. Multiple tensile ropes are arranged in a ring around the outside of the central skeleton, and the multiple tensile ropes are evenly arranged between two cable cores.
[0008] Preferably, the cable core is provided with six cores, and the six cores are distributed in a ring at equal intervals.
