Photoelectric composite power cable and machining process

The invention relates to the field of an electric system, in particular to a photoelectric composite power cable and a machining process. The photoelectric composite power cable comprises an outer coating (1), a first armor layer (2) and a lining layer (3), wherein the outer coating (1), the first armor layer (2) and the lining layer (3) are sequentially distributed from outside to inside, three cable units (4) which are tangent to one another are arranged in the lining layer (3), a reinforcing part (5) is arranged among the three cable units (4), three gaps between the three cable units (4) and the lining layer (3) are filled with multiple filling units, at least one filling unit is an optical cable unit (6), and each cable unit is internally provided with a water blocking tape and a semi-conductive water blocking layer. By the adoption of the structure and the processing methd, the photoelectric composite power cable has the advantages of being good in waterproof performance and long in service life.
