Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1, the present utility model provides an underwater cable, which includes an outer covering member, a core member, and a kevlar filler 6.
The outer wrapping member comprises a flexible jacket layer 2;
the wire core component comprises a flexible wire core A3 positioned at the center of the flexible sheath layer 2 and a flexible wire core B4 which is designed in an outward circular array by taking the flexible wire core A3 as the center of a circle, and the flexible wire core B4 is also positioned in the flexible sheath layer 2, as shown in figure 1, the number of the flexible wire core B4 designs in the utility model is eight;
