Abstract

The invention relates to a waterproof cable. The waterproof cable comprises a cable core and a sheath layer surrounding the outer surface of the cable core, wherein a plurality of fan-shaped conductors and a center conductor are arranged inside the cable core; the fan-shaped conductors are arranged around the outer circle of the center conductor; a wrapping layer is arranged on the outer surfacesof the fan-shaped conductors; the wrapping layer is formed by twining a glass tape, non-woven fabric and a steel wire, and the steel wire is arranged on the outer side of the glass tape and non-wovenfabric; water blocking yarns are arranged at the gaps between the wrapping layer and the fan-shaped conductors; and a water blocking layer is arranged between every two adjacent fan-shaped conductor.The waterproof cable has the advantages of simple structure, low manufacturing cost and good waterproof and insulating effects.

Description

Technical field: [0001] The invention relates to the field of cables, in particular to a waterproof cable. Background technique: [0002] With the rapid development of the national economy, the industry continues to expand, cables are widely used in different environments, and the waterproof performance of power cables is getting more and more attention. For example, cables are used in humid areas in the south, across rivers and seas, and island areas It must pass through water, or be completely immersed in water, and the waterproof effect of traditional cables is poor. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a waterproof cable with simple structure, low manufacturing cost and good waterproof and insulating effect. [0004] The purpose of the present invention is achieved through the following technical solutions: a waterproof cable, including a cable core, a sheath layer surrounding the outer surf...
