Photoelectric composite cable comprising coaxial electrical units and manufacturing method thereof

Abstract

The invention belongs to the technical field of cables and particularly relates to a photoelectric composite cable comprising coaxial electrical units. The photoelectric composite cable is composed of a cable core, a shielding layer and an outer sheath, wherein the shielding layer is wrapped outside the cable core, and the outer sheath is wrapped outside the shielding layer in an extrusion molding mode. The cable core is composed of a cable core inner layer and a cable core outer layer located outside the cable core inner layer. The photoelectric composite cable is characterized in that the cable core inner layer is composed of a reinforcer, the inner-layer coaxial electrical units and filling ropes, wherein the reinforcer is located at the center of the cable core inner layer, the inner-layer coaxial electrical units are distributed along the outer edge of the reinforcer, and the filling ropes are located at outer gaps between the adjacent inner-layer coaxial electrical units; the cable core outer layer is composed of the outer-layer coaxial electrical units, a plurality of optical cable units, a plurality of solid filling strips, a ground lead and tearing ropes. The invention further discloses a manufacturing method of the photoelectric composite cable. The photoelectric composite cable has the main advantages of being wider in purpose, better in shielding performance, more excellent in mechanical performance, smaller in diameter, lower in cost and easier to construct, and the manufacturing method is simple.
