Embodiment Construction

[0016] Such as figure 1 Shown is a marine power communication composite cable, including a communication core conductor layer 1, characterized in that: the communication core conductor layer 1 is sequentially wrapped with a first polyester tape 2, a first shielding layer 3, an inner sheath 4, The power core conductor layer 5, the second polyester tape 6, the second shielding layer 7, and the outer protective layer 8. The communication core conductor layer 1 is composed of several communication core conductors wrapped with insulating materials. The power core conductor layer 5 is composed of several power core conductors wrapped with insulating materials. The insulation material is low-density polyethylene. The first shielding layer 3 is a shielding layer braided by copper wires. The material of the inner protective layer 4 and the outer protective layer 8 is high density polyethylene. The second shielding layer 7 is a shielding layer braided by steel wires.

Abstract

The invention discloses a marine power communication compound cable, which comprises a communication core conductor layer. A first polyester tape, a first shielding layer, an inner protection layer, a power core conductor layer, a second polyester tape, a second shielding layer and an outer protection layer wrap the exterior of the communication core conductor layer in sequence. Firstly, as a structure that a communication core is different in lay ratio when being stranded is adopted by the marine power communication compound cable disclosed by the invention, electromagnetic coupling between adjacent cables can be effectively eliminated; secondly, a copper wire braid layer and a steel wire braid layer are adopted by the marine power communication compound cable to respectively serve as a shielding layer structure, so that the longitudinal resistance to tension of the cable can be improved on the basis that outside high-frequency and low-frequency interference is well shielded; and thirdly, an insulating material of the marine power communication compound cable is low-density polyethylene, so that the cable is good in insulating property, and meanwhile, the electrical performance of the cable cannot be influenced under a moist environment by adopting the inner protection layer and the outer protection layer which are respectively made of high-density polyethylene.

Description

Technical field [0001] The invention relates to a cable, in particular to a marine power communication composite cable. Background technique [0002] At present, marine cables generally have the following problems. First, the power control core and the communication core are usually independent and divided into two, which takes up a lot of space and is inconvenient to use; secondly, the steel tape armored cable has flexibility and longitudinal tension. The breaking force is poor; again, the chlorine component in the PVC sheath of the cable is easy to lose, and there is a problem that the sheath is easy to age and has a low service life. Summary of the invention [0003] The technical problem to be solved by the present invention is to solve the above-mentioned shortcomings of the prior art, and provides a marine power communication composite cable, which can not only solve the problems of the original marine power cable and the communication cable independently occupying large spa...
