Description

Technical Field

[0001] The utility model relates to the field of cables, and specifically to a waterproof aluminum alloy cable. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires.

[0003] At present, the Chinese utility model with the publication number CN217640743U discloses a waterproof cable, including a conductor and a waterproof outer sheath. A water blocking powder is arranged on the outer layer of the conductor, an insulating layer is wound around the outside of the water blocking powder, a waterproof filling layer is arranged between the conductor and the waterproof outer sheath, and a waterproof wrapping layer is arranged on the side of the waterproof filling layer. The waterproof cable of the utility model, with the water blocking powder, insulating layer, waterproof filling layer, waterproof wrapping layer and waterproof outer sheath, forms multiple waterproof layers. Once a non-waterproof break point occurs in other waterproof structures, waterproof protection can be achieved layer by layer until the water blocking powder swells and gels when encountering water, forming longitudinal water blocking for the conductor, and the waterproof effect is good. Applying the technology of the internal and external integration method combining longitudinal water blocking and radial water blocking improves the overall waterproofness of the cable.

[0004] To sum up, compared with the above scheme, it cannot quickly expand when water intrudes, prevent the further diffusion of water and form a waterproof barrier, and at the same time, it cannot provide electromagnetic shielding and enhance the mechanical strength and tensile resistance of the cable. Therefore, we provide a waterproof aluminum alloy cable. Content of the Utility Model
