Rectangular watertight cable for underwater launching

Abstract

The invention relates to a rectangular watertight cable for underwater launching. The rectangular watertight cable comprises data buses, power lines, high-permeability alloy belt shielding layers, silver-plating copper wire shielding layers, a tensile water-resistant fiber water-resistant layer and a sheath, wherein after being stranded, the four data buses are externally wrapped with one high-permeability alloy belt shielding layer in sequence and weaved with one silver-plating copper wire shielding layer so as to form a signal winding; after being stranded, the seven power lines are externally wrapped with one high-permeability alloy belt shielding layer in sequence and weaved with one silver-plating copper wire shielding layer so as to form a power winding; four signal windings and two power windings are arranged horizontally and are externally woven with one tensile water-resistant fiber water-resistant layer, and finally the tensile water-resistant fiber water-resistant layer is externally extruded with one sheath layer to form a rectangle; the sequence for horizontal arrangement of the four signal windings and the two power windings is as follows: the two power windings are arranged in the middle, and the two sides of the two power windings are respectively provided with two signal windings. The rectangular watertight cable has the advantages that the space is saved in engineering use, and the requirement for the streamline design of an aircraft can be met; the cable has the water-resistant function, also has a tensile function, so that the normal working of the signal windings and the power windings can be effectively protected.

Description

technical field [0001] The invention relates to a special cable for underwater launch, in particular to a rectangular watertight cable for underwater launch that is suitable for signal transmission in an environment with strong underwater electromagnetic radiation and prevents electromagnetic wave signal interference from transmission, and adopts a rectangular structure at the same time. It saves space in engineering use and can meet the requirements of the streamlined design of the aircraft. Background technique [0002] Ordinary watertight cables are generally round. In order to achieve multi-channel signal transmission, multiple wire groups need to be placed. The outer diameter of circular watertight cables is larger, and they are installed on the outer shell of the aircraft, which increases the space and affects the streamlined shape of the aircraft. , increasing aircraft drag. Contents of the invention [0003] In view of the deficiencies in the prior art, the presen...
