Problems solved by technology

[0005] However, cables are often damaged by the outside world during logistics, laying, and post-engineering cross-construction projects, so that they cannot meet the safe operation standards. In order to meet the line operation standards, the damaged parts that meet the repair conditions must be repaired. The previous repair method is , using special tape or heat-shrinkable material to wrap the dam...

Abstract

The invention discloses a portable hot melting repairing device and method for a high-voltage cable outer sheath, and the device comprises an adjustable electric temperature hot air gun, a material injection cylinder, a gluing gun, and a heating and melting device. Wherein the material injection cylinder can be assembled on the gluing gun and can be arranged in the heating and melting device. Theportable hot melting repairing device for the outer sheath of the high-voltage cable can quickly repair the outer sheath of the cable, and is simple in structure, convenient to carry and good in repairing effect; the portable hot melting repair method for the outer sheath of the medium-high voltage cable is applied to repair of the cable, is convenient and rapid, can fuse the same materials, and enables the repaired cable to reach a good state without difference from a brand-new cable in sealing and insulating properties.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a portable heat-melt repair device and method for the outer sheath of a high-voltage cable. Background technique [0002] The outer sheath of the power cable is the first line of defense to protect the cable, and its integrity is of great importance to the service life of the cable. The outer sheath of the cable is located on the outermost layer of the cable, and it is mostly made of polyvinyl chloride (PVC) or polyethylene (PE). The main functions of the outer sheath in the structure of the high-voltage cable are: [0003] 1. Protective effect. The cable laying environment is often accompanied by moisture, corrosive substances and termite erosion. For cables with a metal sheath, the outer sheath located on the outermost layer of the cable is designed to protect the metal sheath (such as a corrugated aluminum sheath) from corrosion by surrounding substances. For cables without ...
