Abstract

The invention discloses a cable insulation wire core repairing method, and belongs to the technical field of wires and cables. The method is characterized in that the method comprises the following steps: S1, finding positions, such as breakdown points, crevasses, recesses and disjunctions, of a cable needing to be repaired, and smoothing the repaired positions by using a blade; S2, taking a repair belt with a proper size, and baking and melting the repair belt by using a plastic welding gun until the repair belt is completely attached to the insulating surface; S3, adopting a polishing machine for polishing the attached repairing belt to be flat; S4, adopting an electron irradiation belt for completely winding the repaired position, wherein the resistance between cable cores after repairing can reach 2,500 megohm or above, potential safety hazards are avoided, the service life of the cable for circulating heating in the using process is prolonged, the used materials are free of halogen elements, the environment cannot be polluted, the physical and psychological health of operators is facilitated, and the problems that in the prior art, when a cable is damaged, an insulating wire core needs to be scalped for reproduction, raw materials are wasted, and cable cost is increased are solved.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a method for repairing cable insulation cores. Background technique [0002] XLPE insulated power cable is a kind of cable suitable for distribution network and other fields. It has the incomparable advantages of PVC insulated cable. It has simple structure, light weight, good heat resistance, strong load capacity, non-melting, and chemical corrosion resistance. , high mechanical strength, is to use chemical or physical methods to change the cable insulation polyethylene molecule from a linear molecular structure to a main network molecular structure, that is, thermoplastic polyethylene is transformed into a thermosetting cross-linked polyethylene, thereby greatly improving its performance. Heat resistance and mechanical properties, reducing its shrinkage, making it no longer melt after being heated, and maintaining excellent electrical properties. [0003] When enterpr...
