Embodiment 1

[0025] like figure 1 The shown shaped conductor flexible metal armored optical fiber composite power cable includes a cable core, a flexible metal armor layer 7 wound on the cable core, and an outer sheath 8 extruded on the flexible metal armor layer 7 .

[0026] The outer sheath 8 is made of extruded low-smoke halogen-free flame-retardant polyolefin sheath material, and its oxygen index should not be less than 36. The color of the outer sheath 8 is generally black, and can be adjusted to other colors according to customer requirements.

[0027] The flexible metal armor layer 7 is pre-rolled by aluminum alloy strips, and then wrapped on the cable core by covering, and the overlapping rate of covering is not less than 15%. The aluminum alloy strip of this example has a nominal thickness of 0.5mm.

[0028] The cable core is composed of 3 conductive cores, 1 grounding core, filler 6, and 1 optical cable 3 twisted together. The optical cable 3 is located in the center of the cab...

Abstract

The invention discloses a molded conductor flexible metal armored optical cable composite power cable. The cable comprises a cable core, and is characterized by also comprising a flexible metal armored layer, an outer sheath and an optical cable, wherein the flexible metal armored layer is wound on the cable core; the outer sheath is coated on the flexible metal armored layer in an extruding way; and the optical cable is arranged in the center of the cable core. The flexible metal armored layer is formed by coiling a pre-rolled metal belt lapping cover outside the cable core, wherein the overlapping rate of the lapping cover is not less than 15 percent. The cable has the advantages that the cable core is compact, and flexible armored lapping buckles are buckled one by one, so that the cable is convenient to bend and pave. The cable has mouse-preventing, white ant-preventing and electromagnetic shielding functions, relatively high environment-friendly flame retardant property and certain fire resistance.

Description

technical field [0001] The invention relates to the technical field of optical cables and electric cables, in particular to a flexible metal armored optical fiber composite power cable with formed conductors. Background technique [0002] Optical fiber composite power cables are used in the construction of smart communities as part of the development of smart grids. However, in the past, optical fiber composite power cables only added an optical cable to ordinary power cables, and the conductive core of the cable used a circular structure. Such a cable not only has a large outer diameter, but also is not round when it is cabled, and because the cable core structure is not compact enough, the flame retardancy of the cable is poor. The armored cable with double-layer overlapping steel strips is not flexible enough to bend, and it is difficult to bend when laying. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a f...
