Embodiment Construction
[0020] The present invention will be further described below in conjunction with the drawings.
[0021] Such as figure 1 A multi-layer split conductor water-blocking power cable with built-in optical fiber is shown. The center of the cable is provided with a split conductor layer. The split conductor layer is composed of a plurality of divided sector-shaped conductor strands 1 and each sector-shaped conductor strand block. The outer sector-shaped strand water-blocking layer 2 is assembled, and the water-blocking rope 5 is filled in the central gap after the multiple sector-shaped strand water-blocking layers are assembled; each sector-shaped conductor strand is provided with a circle Shaped conductor 3, each round conductor is provided with a circular water blocking layer 4; between the fan-shaped corners of the fan-shaped strand water blocking layer, there are five wire bundles 10 that are directly dragged with the optical fiber unit 9; The gap between the water blocking layer, ...
