A kind of cable and method for manufacturing cable

Abstract

The invention belongs to the technical field of electric power equipment, and specifically relates to a cable and a method for manufacturing the cable, including a metal conductor, an insulating layer and a film layer; the metal conductor is formed by twisting metal monofilaments; the insulating layer is wrapped in The surface of the metal conductor; the film layer is coated on the outer side of the metal conductor wrapped by multiple insulating layers; the outer side of the film layer is sleeved with a water-stop layer; the water-stop layer is made of water-swellable rubber material; The outer layer of the water layer is sleeved with an outer sheath tube; the space between the film layer and the water-stop layer is filled with talc powder; the inner wall of the water-stop layer is provided with uniformly distributed negative pressure chambers; There are uniformly arranged conduits distributed between them; the negative pressure chamber is fixedly connected with an outlet pipe; the outlet pipe runs through the outer sheath pipe; the present invention prepares positive-nonanoic acid vanillic acid into solid particles and evenly injects them into the outer layer In the sheath tube, it is vaporized to form uniform air bubbles in the outer sheath tube, so as to achieve the purpose of preventing rodents.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to a cable and a method for manufacturing the cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. Most of them are installed in the air or installed underground or underwater for telecommunications or power transmission. Most of the cable erection areas are often infested with mice, and because the cables have a special attraction to mice, they often cause mice to bite the cables, resulting in short circuits in the cables. , leakage and other situations occur, and in severe cases, the cable will be disconnected, resulting in fire and other safety hazards; Cables with steel tape armor are bulky. [0003] A Chinese patent for a rodent-proof data cable, the patent number is 2...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art and solve the problem that the cable sheath is easily damaged by mice and the existing rodent-proof cables will cause harm to the human body during installation and affect the progress of cable installation, the present invention proposes a cable and a method for manufacturing cables method
