BACKGROUND OF THE INVENTION An optoelectronic composite cable (OPGW 0PPC) is used as a composite line with dual functions of common overhead ground/phase line and optical fiber communication capability for power system communication. Photoelectric composite cables are commonly used in two structural forms: layer-twisted photoelectric composite cables (single-tube, composite pipe, stainless steel pipe) can be double or triple; central tubular photoelectric composite cable (single pipe, composite pipe, stainless steel pipe) Can be single or double layer. The fiber unit is composed of a central cable core or a skeleton and a protective tube in which a plurality of optical fibers or cores are placed. Protect the cable from damage caused by extrusion, bending, torsion, tensile stress and moisture. Fibers generally use single-mode fiber. Because single-mode fiber has small attenuation and frequency bandwidth, it can provide large system transmission capacity, meet large-span and long-distance transmission, and reduce the number of line repeaters. The existing photoelectric composite cable structure has poor bending resistance and torsion performance, and the photoelectric composite cable construction method is complicated and the cost is high.
