Optical fiber composite low-voltage power cable

Abstract

The invention is applicable to the technical field of a cable, and discloses an optical fiber composite low-voltage power cable. The optical fiber composite low-voltage power cable comprises an outer insulating composite sleeve, conductors and an optical unit, wherein the outer insulating composite sleeve comprises an outer sheath insulating layer, a metal armor layer, an inner lining insulating layer and a warping tape layer; each conductor comprises a metal core wire and a core wire insulating sleeve; the optical unit comprises a composite protection sleeve and optical fibers positioned in the composite protection sleeve; the optical fibers comprise 12 fiber cores; a cladding layer is arranged on the exterior of each fiber core; a polyacrylonitrile carbon fiber bundle is also arranged in the protection sleeve; the polyacrylonitrile carbon fiber bundle is sleeved with a shaping sleeve; the composite protection sleeve comprises a silica gel pipe and a coating layer on the inner side of the silica gel pipe; the thickness of the silica gel pipe is greater than or equal to 25% of the diameter of each conductor; and the interior of the warping tape layer is filled with a non-hygroscopic filler. The optical fiber composite low-voltage power cable provided by the invention can prevent the optical unit from being damaged caused by pulling and bending, so as to ensure communication reliability and continuity, so that the product has excellent reliability.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to an optical fiber composite low-voltage power cable.
