Photoelectric composite cable with special-shaped filling material

Abstract

The invention belongs to the technical field of cables, and relates to a photoelectric composite cable with a special-shaped filling material. The cable comprises a reinforcing part, a plurality of power transmission conductors which are located at an outer side of the reinforcing part and sequentially tangential or slightly separated, optical fiber communication units located in gaps outside the adjacent power transmission conductors, a protection layer wrapping the power transmission conductors and the optical fiber communication units, and a sheath layer which covers the protection layer in an extruding manner. The cable is characterized in that the gaps outside the adjacent power transmission conductors are provided with special-shaped ropes; the special-shaped ropes are formed by the sequential jointing or one-time extrusion molding of a plurality of small-structure filling rope bodies; the outer edges of the small-structure filling rope bodies are respectively a complete cylindrical surface; the power transmission conductors respectively consists of a conductor and an insulating body; and the optical fiber communication units respectively consists of an optical fiber and a protection tube wrapping the optical fiber. The special-shaped ropes are made of materials with a special formula. The cable provided by the invention is simple in structure, is lower in cost, is better in performance, and is more convenient in construction.

AI Technical Summary

Problems solved by technology

However, the existing photoelectric composite cables mainly have the following problems: (1) When the outer gap between the adjacent conductors is large, in order to make the composite cable round and round, the loose tube that accommodates the optical fiber also needs to be made into a large size. Increased cost; (2) The wire and the loose tube are twisted to form a cable core, and the outside of the cable core is wrapped with a yarn-like substance, which is easy to damage the loose tube, causing abnormal optical signal transmission, and when the temperature changes significantly, the wrapping The substance damages the loose tube, thereby affecting optical communication, and the dressing material itself is expensive; (3) It is not easy to remove the loose tube by twisting the wire and the loose tube, and the dressing material needs to be cut before taking it out. It is easy to damage the cable core, and it is not easy to restore; and it is very troublesome to take out the loose tube
