58-core composite cable

Abstract

The present invention relates to a 58-core composite cable used for a ship missile launching system. A 0.35 mm2 twisted pair shielding cable and two 1553B data buses are twisted into a bundle to form a cable core I; 12 0.35 mm2 shielding single cables and 18 0.35 mm2 shielding single cables are arranged in order on the outside of the cable core I to form a cable core II into a bundle; and a 1.5 mm2 twisted pair cable, two 2.5 mm2 twisted pair cables, a 1.2 mm2 twisted pair cable, a 3.0 mm2 twisted pair cable, a 1.2 mm2 twisted pair shielding cable, two 2.0 mm2 twisted pair shielding cables, two 1.2mm2 twisted pair shielding cables and a 3.0 mm2 twisted pair cable are arranged clockwise on the outside of the cable core II to form a cable core III into a bundle. The outside of the cable core III is provided with a flame-retardant isolation layer I, a total shielding layer, a flame-retardant isolation layer II, and a sheath in order. The structure is a customized cable for the upgrade and update of an overall unit, wherein cable groups and arrangements have unique corresponding relationships with an overall unit system.

Description

technical field [0001] The invention relates to a multi-core integrated cable, in particular to a 58-core integrated cable used in a ship missile launching system. Background technique [0002] Existing ship cables are cables used for various ships in rivers and seas and offshore or offshore buildings, which can realize functions such as lighting, control, communication transmission, etc., including marine power cables, marine control cables, marine communication cables, etc. Single function cable. [0003] A few ship integrated cables can realize the integration of signal and power transmission, but they are all customized for the specified system according to the connector position. With the upgrading of the whole machine system, the composition of the cable neutral group and the cable structure can no longer meet the needs, and the twisted pair or twisted pair shielded wire used in the original integrated cable has a low transmission rate and cannot guarantee the integri...

Problems solved by technology

With the upgrade of the whole machine system, the composition of the cable center line group and the cable structure can no longer meet the needs, and the twisted pair or twisted pair shielded wire used in the original integrated cable has a low transmission rate and cannot guarantee the integrity of the signal Defects

[0004] Ordinary ship cables use a single insulating material, which cannot meet the requirements of softness, low-smoke and zero-halogen, and insulation heat shrinkage at the same time.

Large-section polyethylene insulated wire cores have poor thermal shrinkage performance, and ethylene-propylene rubber insulation has poor mechanical and physical properties, so they are not suitable for small-section insulated wire cores.
