Dragging optical and electrical composite cable

Abstract

The invention discloses a dragging optical and electrical composite cable. The dragging optical and electrical composite cable comprises two power lines and an optical cable, wherein the power lines and the optical cable are twisted into a composite cable; a waterproof layer is encapsulated outside the composite cable; a waterproof yarn knitted layer is further filled between the composite cable and the waterproof layer; an aramid yarn knitted layer is encapsulated outside the waterproof layer; a sheath layer is encapsulated outside the aramid yarn knitted layer; the cable comprises a plurality of fiber units, an internal anti-flaming layer is extruded outside the fiber units, an external anti-flaming layer is encapsulated outside the internal anti-flaming layer, and the aramid yarn knitted layer and the waterproof yarn knitted layer are further filled between the internal anti-flaming layer and the external anti-flaming layer; each power line comprises stranded silver-plated copper wires, the silver-plated copper wires are twisted into a copper wire beam, and an insulating layer is encapsulated outside the copper wire beam. Compared with the prior art, the dragging optical and electrical composite cable has the advantages of small external diameter, light weight, low cost, stretching and pressure resistance, high bending performance and the like, is green, environmentally-friendly, wearproof, oilproof and resistant to low temperature, can be safely used for a long period of time, can be applied to interior and outdoor mobile communication systems, and is convenient in construction and stable in operation.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a dragging photoelectric composite cable. Background technique [0002] Due to the different transmission purposes of optical cables and cables, there are great differences in the fields of application and the level of professional technology involved. At present, in the wiring system of mobile communication equipment, the power line and the communication line are wired independently, the wiring cost is high and the wiring process is cumbersome, and the sheath material and unit structure used are prone to wear and tear on the outer sheath and core damage of the cable during long-term operation. and other faults, affecting communication transmission and power supply, it is difficult to troubleshoot lines, and the maintenance cost is high. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of ...
