Abstract

The invention discloses a repair method of a damaged cable. The repair method comprises the following steps that: S1, a damaged portion of the cable is cleaned and dried; S2, an UV adhesive is injected into the damaged portion cleaned in the S1, the UV adhesive is initially cured through an UV lamp, so that a first UV adhesive layer can be formed; S3, a first metal net is laid on the surface of the first UV adhesive layer formed in the S2; and S4, the UV adhesive is injected into the surface of the first metal net mentioned in the S3 again, and the UV adhesive is cured through the UV lamp, so that a second UV adhesive layer can be formed, and the outer surface of the second adhesive UV layer and the surface of the shell of the cable are located in the same cambered surface. With the above steps adopted, the damaged portion of the cable can be repaired, and the shielding performance of the cable will not be affected at all; and the first UV adhesive layer is initially cured, and therefore, the first metal net can be well embedded in the UV adhesive, and an outermost layer has the greatest bonding strength, and therefore, the repaired portion will not fall off assuredly.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary equipment, in particular to a method for repairing damaged cables. Background technique [0002] In the secondary circuit of the power system, the application of power cables is more and more extensive. The cables have four cores, seven cores, or even more than a dozen cores. The sheath; the cable is composed of one or several insulated wires, which are covered with a tough outer layer made of metal or rubber. During the use of the cable, due to the influence of the external weather, the friction between the cable and the tower rod will cause the outer protective layer of the friction part to be damaged, which is prone to leakage and short circuit; the fixed seat is prone to oxidation after being damp, and the humidity and humidity in the air will be caused by air pollution. Higher acidity will lead to faster cable damage, and overlapping voltage rise and drop occurs, and the cab...
