Description
Technical Field

Background
The photoelectric composite cable has the functions of power transmission and network signal transmission, and can swing under the impact of a dark current in the operation process of an umbilical cable applied underwater to connect a water surface ship and underwater operation equipment due to the existence of the dark current of seawater. Because the weight of the photoelectric composite cable is heavy, the photoelectric composite cable also has great inertia when swinging in water, so that the connection between the cable and equipment at two ends can be influenced, underwater operation equipment can be pulled, and in addition, the transmission performance of internal light can be reduced due to transitional swinging of the cable.

As shown in the figure, the maximum distance between the countercurrent surface and the inner cladding 11 is less than the maximum distance between the countercurrent surface and the inner cladding 11, and the top radian of the countercurrent surface is greater than the top radian of the countercurrent surface, so as to ensure that the outer cladding 10 has good structural strength, the thickness of the outer cladding 10 at the front end part of the countercurrent surface and the forward surface is greater than the thickness of the left side and the right side, and the built-in framework 15 is embedded respectively at the top of the countercurrent surface and the top of the forward surface. In addition, as shown in fig. 2, the drag reduction sheath is provided with middle partition plates 19 at equal intervals, and the middle partition plates 19 are fixedly connected with the outer cladding 10 and the inner cladding 11.
