Pre-buried composite pipe cable and manufacturing method thereof

Abstract

The invention relates to a pre-buried composite pipe cable and a manufacturing method thereof, and belongs to the technical field of composite pipe cables. The technical scheme of the invention is that 1, a single copper wire or a single aluminum alloy wire forms a conductor (1), or multiple copper wires or multiple aluminum alloy wires are concentrically twisted to form the conductor (1), and theconductor (1) is wrapped by an insulating part (2) to form wire cores through extruding; 2, the wire cores are twisted together to form a cable core, wherein there is no wrapping and filling outsidethe cable core; 3, the cable core are extruded in a polyethylene pipe (3) and enters into the pipe, the cable core is paid off from a pay-off rack and is pulled through two pay-off machines to enter the head of a pipe-extruding machine and pass through a wire-passing die core at the head of the pipe-extruding machine, and the polyethylene pipe is extruded through the pipe-extruding machine, the polyethylene pipe outside the cable core is molded and cooled by a vacuum setting zone, and then is wound by a tractor to a reel. The method avoids secondary laying during construction, reduces construction cost, and prevents the damage to the cable caused by secondary construction from affecting normal operation of the cable.

Description

technical field [0001] The invention relates to a pre-embedded composite umbilical cable and a manufacturing method thereof, belonging to the technical field of composite umbilical cables. Background technique [0002] Cables are an indispensable element in the process of urban construction. The usual mode for cable construction is to build cable trenches and place cables for laying pipes. The other end pulls the cable to the other end of the pipeline through ropes or other materials to complete the pipeline laying of the cable, but during such laying, it often occurs that the cable is scratched and worn due to friction with the pipeline. There will be a problem of cable breakage, which will greatly affect the normal laying and safe use of the cable, and bring great hidden dangers to the safe operation of the cable.
