Abstract
The invention discloses a photoelectric composite medium-voltage fireproof lock type cable, belongs to the technical field of power cables, and aims to provide the photoelectric composite medium-voltage fireproof lock type cable, for increasing the efficiency of setting a protective layer outside multiple strands of wire cores. The cable comprises a cable core and a protective layer; each strand of wire core comprises multiple sets of core materials and an insulating layer; the space between the core materials and the insulating layer is filled with a second filling layer; the outer cylindrical surface of the insulating layer of each strand of wire core is provided with a locating bulge; a first grooved structure is arranged on the side surface of the locating bulge; a second groove is arranged below the locating bulge; a raised edge bulge is arranged at the outer end of the second groove; the outer cylindrical surface of the insulating layer of each strand of wire core is provided with a second grooved structure; a bulge structure is arranged below the second grooved structure; a clamping groove matched with the edge bulge is arranged at one end of the bulge structure; and, when adjacent two strands of wire cores are connected, a locking strip is installed in a space, which is formed by the first grooved structure of a strand of wire core and the second grooved structure of the other strand of wire core.
