[0011] Furthermore, the anti-bite layer is a wire mesh cage.

[0012] Furthermore, the anti-corrosion layer is a polyethylene coating tape.

[0013] Furthermore, the cross-sectional shape of the pressure-resistant layer is a triangle.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The underwater high-water-pressure-resistant cable can improve the overall tensile resistance of the cable by providing tensile ribs in the protective layer, and can improve the lateral compressive resistance of the cable. A compressive layer with a triangular cross-section is provided on the outer surface of the cable core to improve the longitudinal compressive resistance of the cable.
