Watertight tractive load-bearing control cable

Abstract

The invention discloses a watertight tractive load-bearing control cable. The watertight tractive load-bearing control cable comprises a copper conductor formed by bundling a plurality of strands of copper wires. A sealing layer I is formed by coating the copper conductor with a sealant. An insulated cable core is formed by extruding a TPV elastic body insulating layer outside the sealing layer I. A waterproof layer is formed by filling gaps among the cable cores with waterproof glue when a finished cable is formed by stranding the cable cores. Waterproof wrapping tape is wound around the finished cable. An armor aramid fiber tensile enhancement layer is wound around the waterproof wrapping tape, waterproof wrapping tape I is wound around the aramid fiber tensile enhancement layer. A polyurethane inner sheath is extruded outside the wound waterproof wrapping tape I. A shielding layer is formed outside the inner sheath by weaving tinning annealed copper wires and is coated with a sealant so that a sealing layer II can be formed. A polyurethane outer sheath is extruded outside the sealing layer II. The watertight tractive load-bearing control cable is reliable in longitudinal watertightness performance, good in flexibility, light in weight, resistant to wear and bending, good in tension resistance, and can normally maintain reliability of electric transmission and control signal transmission under certain water pressure.

Description

Technical field [0001] The present invention involves a kind of water -deleted drag -controlled control cable, which is the field of wire and cable. Background technique [0002] With the continuous development of science and technology, the water -mounted series cable is an indispensable information transmission component in the field of underwater and marine technology.During the detection of the ocean, an underwater detection device often needs a umbilical cord cable to connect to the mother ship with a reliable signal connection and mechanical connection in the actual use process.Drag the water delayed heavy cable.Water deleted dragging heavy cables has excellent environmental adaptability, can resist water and tensile strength, and can repeatedly bend and use it for hundreds of times under the radius of the small bending radius.It must not only ensure the reliability of power transmission and control signal transmission in normal conditions, but also to ensure the safety of ...

AI Technical Summary

Problems solved by technology

[0003] The patent of the present invention is to provide a watertight towing load-bearing control cable, which successfully solves the problem of insufficient longitudinal watertightness of ordinary underwater load-bearing towing cables, making the cable have excellent Watertight, can maintain the reliability of power transmission and control signal transmission under certain water pressure conditions, and has a high strength-to-weight ratio, flexible bending characteristics, excellent corrosion resistance, wear resistance and repeated retractable capabilities
