Embodiment Construction

[0052] see Figure 4 , the present invention proposes a flexure-resistant and highly flexible floating cable, which includes a core group 5 , a wrapping layer 6 , a filler 7 , a floating core group 8 , and an outer cladding layer 9 .

[0053] The wire core set 5 includes a conductor 52 and an insulating layer 54 .

[0054] The conductor 52 is formed by twisting tinned annealed copper wires.

[0055] The insulating layer 54 covers the outside of the conductor 52 and is made of hydrogenated styrene-butadiene-styrene block copolymer (SEBS) thermoplastic elastomer, which is excellent in flexibility and resilience.

[0056] The wrapping layer 6 is wound outside the core set 5 .

[0057] The filler 7 is filled between the wire cores and between the wrapping layer 6 and the wire core group 5 .

[0058] The floating core group 8 is wrapped on the outside of the wrapping layer 6. The floating core group 8 is a foam layer made of hydrogenated styrene-butadiene-styrene block copolymer...

Abstract

A bending-resistant highly-flexible floating cable comprises a wire core group, a winding package layer, a floating core group and an outer coating layer. Each wire core comprises a conductor and an insulating layer which coats the outside of the conductor. The insulating layer is made of the thermoplastic elastomer of the hydrogenated styrene-butadiene-styrene block copolymer. The winding package layer winds the outside of the wire core group. The floating core group coats the outside of the winding package layer, is a foaming layer and is made of the thermoplastic elastomer of the hydrogenated styrene-butadiene-styrene block copolymer. The outer coating layer coats the outside of the floating core group and is made of the modified thermoplastic polyurethane elastomer (TPU) or modified nylon. The invention also provides a manufacturing method, material formula and a preparation process of the cable. The floating cable has good bending endurance performance, good flexibility and small radius of bending curvature, is easy to operation and suitable for frequent bending and is frequently used by deploying and retracting.

Description

technical field [0001] The invention relates to a transmission cable, in particular to a floating or suspended cable in water. Background technique [0002] In the fields of underwater detection and salvage, it is necessary to use cables to transmit power and command signals to underwater machines and equipment. Since the overall density of conventional cables is much higher than that of water, the self-weight of these transmission cables causes them to sink. When equipment and devices When the water is very deep, the cable is very long, and its sinking force will cause the cable connection on the shore or ship to break or even cause the cable itself to break. At the same time, when the underwater equipment is moving, due to the friction between the sinking cable and the underwater surface, it is difficult to move the equipment, and it is easy to cause the outer sheath of the cable to break, causing accidents such as underwater leakage and signal distortion. In order to pre...
