Problems solved by technology

At present, there have been applications of fiber optic composite low-voltage cables at home and abroad, but unfortunately, the current products generally have thick outer diameters, and the fiber optic cable unit is mixed with the cable unit; because the normal operating environment of the fiber optic is -40 degrees Celsius to +70 degrees Celsius , and the high temperature during cable operation usually exceeds the above range, so the twisted structure cannot meet the requirements of reliable operation

Abstract

The invention belongs to the technical field of cables, and in particular relates to an improved optical fiber composite low-voltage cable. The improved optical fiber composite low-voltage cable is characterized by comprising low-voltage insulation phase lines, a first protection layer, an optical fiber belt, a second protection layer and an outer protection layer, wherein the first protection layer covers the low-voltage insulation phase lines; the optical fiber belt is distributed at the periphery of the outer part of the first protection layer; the second protection layer covers the optical fiber belt; the outer protection layer covers the second protection layer; a conductor is arranged in each low-voltage insulation phase line; an insulation layer is arranged outside each low-voltageinsulation phase line; the cross sections of the conductor and the insulation layers are fan-shaped, and any two adjacent low-voltage insulation phase lines on anyone of the cross sections are connected by virtue of non-arc edges of the insulation layers, and outer arcs of all the insulation layers are on the same circle; and the axes of any two optical fibers contained in the optical fiber belt are parallel mutually; and the optical fiber belt clings to the first protection layer. The invention also discloses a manufacturing method of the cable. According to the invention, outer diameter andmaterial consumption of the cable are reduced, the heat emission of the cable hardly influences the optical fiber, the product performance is more stable and reliable, and the cable provided by the invention is simple to manufacture.

Description
