Embodiment
[0044] Such as figure 1 and figure 2 A twist-resistant optical-electrical hybrid cable is shown, which includes:
[0045] The cable core 1 and the outer sheath 2 coaxially coated on the outside of the cable core 1 to protect the cable core 1 .
[0046] Described outer sheath 2 is polyethylene outer sheath 2, and it is as figure 2 As shown, there are three layers of outer layer 201, middle layer 202 and inner layer 203. The inner layer 203 is tightly wrapped on the outer surface of the cable core 1, and the outer rib 204, middle layer 202 and inner layer 202 are arranged between the outer layer 201 and the middle layer 202. The inner ribs 205 are arranged between the inner layers 203, and the outer ribs 204 and the inner ribs 205 are evenly arranged along the circumferential direction. The arrangement of the outer ribs 204 and the inner ribs 205 makes the three-layer structure of the polyethylene outer sheath 2 separate from each other. 1. The three-layer outer sheath 2 th...

The invention relates to the field of optical cables, in particular to an anti-distortion photoelectric hybrid cable. The cable comprises a cable core and an outer sheath which are coaxially arranged,wherein the outer sheath wraps the cable core and protects the cable core; the outer sheath is of a three-layer structure and comprises an outer layer, a middle layer and an inner layer from outsideto inside; a plurality of outer ribs are evenly arranged between the outer layer and the middle layer in the circumferential direction; a plurality of inner ribs are evenly arranged between the middlelayer and the inner layer in the circumferential direction; the outer ribs separate the outer layer from the middle layer; and the inner ribs separate the middle layer from the inner layer. The cablecore is formed by wrapping a central sleeve with an inner sheath, and the central sleeve is internally provided with an optical fiber wire group and a conductive wire along the axial direction of thephotoelectric hybrid cable. The requirement for cross-sea laying of the photoelectric hybrid cable can be met; the laying difficulty of the photoelectric hybrid cable can be reduced; and the cost ofthe photoelectric hybrid cable can be greatly reduced.
Description
technical field [0001] The invention relates to the field of optical cables, in particular to an anti-twist photoelectric hybrid cable. Background technique [0002] Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication communication that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. cable assembly. The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. A communication line to realize optical signal transmission. That is: a cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of an optical cable is generally composed of several parts such as a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are components such as a waterproof layer, a buffer layer, and an ins...
