The present disclosure provides a waterproof cable, which belongs to the field of cable design. The waterproof cable includes a cable core, an insulating layer, a first waterproof layer and a second waterproof layer that are assembled together in sequence from the inside to the outside, and a flow channel for fluid circulation is arranged between the first waterproof layer and the second waterproof layer. A plurality of annular spacers are arranged in the channel, and the plurality of annular spacers are arranged at intervals along the axial direction of the flow channel. The outer peripheral wall and the inner peripheral wall of the second waterproof layer are respectively provided with a first spiral groove and a second spiral groove. The first spiral groove and the second spiral groove both extend along the axial direction of the second waterproof layer, the second waterproof layer is provided with a plurality of water guide hole groups arranged at intervals, and each water guide hole group is arranged in sequence along the axial direction of the second waterproof layer, each Each water guide hole group includes a plurality of water guide holes. The waterproof cable provided by the present disclosure can effectively prevent the infiltration of water and effectively prolong the service life of the cable.
Description
technical field [0001] The present disclosure belongs to the field of cable design, and in particular relates to a waterproof cable. Background technique [0002] Cable is one of the indispensable materials in the process of power transmission. With the continuous development of technical conditions, the requirements for cables in all walks of life are getting higher and higher. [0003] In the electrical components of marine equipment, the waterproof performance of the cable is crucial to the safe operation of the equipment. In the related art, in the marine humid environment, the cable is provided with a waterproof layer outside the cable core to prevent the infiltration of water, thereby prolonging the service life of the cable. [0004] However, although the above-mentioned waterproof layer has a certain waterproof effect, a cable that is in a humid environment for a long time still has a high risk of water infiltration, thereby reducing the service life of the cable. ...
