Problems solved by technology

[0002] With the rapid development of the communication industry, the use of optical cables, photoelectric composite cables, and photoelectric hybrid cables is increasing. The conductors in the currently used photoelectric hybrid cables mainly use copper conductors and aluminum conductors. Copper conductors have poor corrosion resistance and heavy weight. , expensive and other characteristics; aluminum conductors have poor creep resistance due to their large elongation, and cannot avoid the problem of loose joints at low temperatures; the current photoelectric hybrid cables are not compatible with high shielding performance and excellent lightning protection impact performance, low weight, high bending performance

Abstract

The invention belongs to the technical field of cables, and particularly relates to an optical-power composite cable with a metal sheath employing soft aluminum alloy profile conductors. The optical-power composite cable comprises a cable core, a cable wrapping tape (3), an armor layer (5), a tearing component (4) and an outer sheath (6), wherein the tearing component (4) is located between the cable wrapping tape and the armor layer; the outer sheath (6) coats the outside of the armor layer; the optical-power composite cable is characterized in that the cable core comprises a central cable unit, three peripheral cable units and three power line units; the three peripheral cable units are distributed outside the central cable unit at intervals; each peripheral cable unit comprises two single-core cables (12), two filled ropes (11) and a cable sheath (13); each cable sheath (13) coats the outside of the corresponding single-core cables and filled ropes in an extruding manner; and the single-core cables and the filled ropes are in staggered distribution, and are twisted together. The optical-power composite cable provided by the invention has the technical effects of being easy to peel, light in weight, high in strength, good in creep resistance, soft, high in lateral pressure resistance, excellent in waterproof capability, high in universality, excellent in shielding effect, high in lightning protection performance, easy to bend and the like.
