AI Technical Summary
Existing cables have a simple structure, making them prone to leakage and short circuits. They also have poor waterproof performance in humid environments, which can lead to damage or cracking of the insulation layer and shorten the cable's lifespan.
It adopts a multi-layer structure design, including a shaping component, a cable core unit, an armor layer, a waterproof layer, a water-insulating layer, and a buffer layer. A cavity support plate and a pressure-resistant strip are provided between the armor layer and the shaping component. Specific materials such as low-density polyethylene, cross-linked polyethylene, and EPDM rubber are used to enhance the pressure resistance and waterproof performance.
It improves the cable's compressive strength and waterproof performance, extends the cable's service life, and prevents insulation layer damage and cracking.
