Description

Technical Field

[0001] This utility model relates to the field of cable technology, and more particularly to an aluminum-plastic longitudinally wrapped tin-plated copper flexible cable for underwater use. Background Technology

[0002] Most current cables use cross-linked polyethylene (XLPE) insulation. During use, if moisture enters the polyethylene insulation layer, water trees will form under the influence of an electric field. The formation of water trees increases cable dielectric loss, reduces insulation resistance and breakdown voltage, and significantly shortens cable life. Existing waterproof cables also have inadequate structures, affecting their waterproof performance. Utility Model Content

[0003] The purpose of this invention is to provide an underwater aluminum-plastic longitudinally wrapped tin-plated copper flexible cable to solve the problems in the prior art.

[0004] The technical solution of this utility model is: an underwater aluminum-plastic longitudinally wrapped tinned copper flexible cable, the cable comprising multiple insulated cores, each insulated core consisting of a tinned soft copper conductor and an insulating layer disposed outside the tinned soft copper conductor, the multiple insulated cores being wrapped with a water-blocking tape to form a cable core, with filler between the multiple insulated cores and the water-blocking tape, the cable core being longitudinally wrapped with an aluminum-plastic composite tape, the aluminum-plastic composite tape being provided with an armor layer, and the armor layer being extruded with an outer sheath.

[0005] Preferably, the insulating layer is an XLPE insulating layer.

[0006] Preferably, the filler is a polyurethane waterproof adhesive.

[0007] Preferably, the armor layer is a tin-plated copper wire armor layer.

[0008] Preferably, the outer sheath is a low-smoke halogen-free outer sheath, and the surface of the outer sheath is coated with a polyurethane waterproof coating.

[0009] The beneficial effects of this utility model are: it can stably transmit power in the underwater environment, providing a reliable power connection for underwater equipment, which is especially important in the fields of marine engineering, underwater exploration, and submersible operations, ensuring the normal operation of underwater equipment.

[0010] Tin-plated soft copper conductors can significantly improve the corrosion resistance and oxidation resistance of cables, extending their service life. In underwater environments, cables are easily affected by seawater erosion and oxidation, while tin-plated copper layers can effectively resist these adverse factors and maintain the cable's good performance.

[0011] This invention has good flexibility and bending resistance, and can adapt to the complex and ever-changing underwater wiring environment. Attached Figure Description

[0014] An underwater aluminum-plastic longitudinally sheathed tinned copper flexible cable is used. The cable includes multiple insulated cores, each consisting of a tinned copper conductor 1 and an insulation layer disposed outside the tinned copper conductor 2. The multiple insulated cores are wrapped with a water-blocking tape 4 to form the cable core. A filler 3 is provided between the multiple insulated cores and the water-blocking tape 4. The cable core is longitudinally wrapped with an aluminum-plastic composite tape 5. An armor layer 6 is disposed outside the aluminum-plastic composite tape 5. An outer sheath 7 is extruded outside the armor layer 6.

[0015] The insulating layer 2 is an XLPE insulating layer.

[0016] The filler 3 is a hygroscopic filler and is filled with polyurethane waterproof adhesive.

[0017] The armor layer 6 is a tin-plated copper wire armor layer.

[0018] The outer sheath 7 is a low-smoke halogen-free outer sheath, and the surface of the outer sheath 7 is coated with a polyurethane waterproof coating.

[0019] In this utility model, the aluminum-plastic composite strip with a 5-longitudinal wrapping structure can reduce seams, improve waterproofness, and provide good electromagnetic shielding effect.

[0020] The combination of tin-plated copper wire armor layer 6 and aluminum-plastic composite tape 5 can improve the flexibility and fatigue resistance of the cable, making it suitable for dynamic laying environments.

[0021] Tin plating prevents copper conductors from oxidizing in humid environments, extending cable life. Tinned copper wire is more corrosion-resistant than ordinary copper wire while maintaining good conductivity.

[0022] The outer sheath 7 uses low-smoke halogen-free sheath material to meet environmental and safety standards. Waterproof coating is applied to the outer sheath 7 using a three-coat, three-bake process, with each coating cured by hot air at 60°C.
