Abstract

The invention is a watertight towing photoelectric composite cable and its preparation method. Its structure includes a double-core cable unit, an optical cable unit, a tensile strength member, filled with water-blocking glue, a wrapping layer, and a sheath layer, wherein the cable unit and the optical cable unit are Tensile strength member, the cable unit is filled with water blocking, the outer periphery of the optical cable unit, cable unit, and tensile strength member is a wrapping layer, and the outer periphery of the wrapping layer is a sheath layer. Advantages: This product organically combines electric power transmission by cables and high-performance signal transmission by optical cables. It has strong information throughput and high-speed data transmission, realizes seamless docking between underwater submarines and combat groups, and meets the requirements of horizontal and vertical watertightness and floating. High tensile strength, flex resistance, oil resistance, aging resistance and other characteristics, can be repeatedly retracted and reused, as key components of underwater maintenance detection equipment and seabed positioning equipment,? Effectively ensure the power supply of the probe head and the transmission and use of the probe signal.

Description

technical field [0001] The invention is a watertight towed photoelectric composite cable and a preparation method thereof, which is suitable for power transmission and signal transmission of equipment in the environment of floating buildings such as submarines, warships, river and sea ships, and offshore oil platforms. Background technique [0002] Submarines have great deterrence in attacking targets underwater, but there are limitations in underwater communication, which leads to limited command capabilities for submarines and is difficult to adapt to the needs of modern information warfare. In order to solve the problem of deep hidden communication of submarines and enhance the ability of underwater submarines to guard and observe, towed buoys are installed on submarines in many countries, and connected by towed cables for signal transmission. This product refers to MIL-DTL-24643, GJB1916-94, GJB1428B-2009, GJB1427A-99 and other relevant standards. The photoelectric compo...
