How to repair broken insulation in low voltage plastic insulated power cables

1. Heat welding repair method: heat welding method is to use a power suitable soldering iron, with the iron heat to make the insulation fusion. Low-voltage PVC insulated power cables: PVC material is a thermoplastic material, as cable insulation layer damage repair should be used in the form of heat welding. In order to ensure and strengthen the electrical properties and mechanical properties of the repair place, the use of insulating tape on the repair place for a single layer of overlap wrapping, wrapping should be flat; low-voltage crosslinked polyethylene insulated power cables: crosslinked polyethylene material belongs to thermosetting materials, silane crosslinking insulation molecules after mesh curing. In the insulated core boiling water crosslinking process before the insulation damage repair using hot welding repair, and then use transparent tape to repair the place for wrapping, to prevent the repair from falling off; in the insulated core boiling water crosslinking process, the insulation layer damage should be repaired by hot welding, and then use the 35kV level of high-voltage self-adhesive tape overlap package, and ensure that the high-voltage tape wrapping must be flat. 2. Heat-shrinkable tube repair method: Heat shrink tubing repair method is the right size of heat shrink tubing in the defective point, heat shrinkage and tight package defects. Regardless of the insulation material using thermoplastic polyvinyl chloride material or thermosetting cross-linked polyethylene material, the nominal cross-section of less than 10mm2 insulation core, should be used to repair the heat shrinkable tube, heat shrinkable tube repair is completed, wrapped with insulating tape. 3. Comparison of repair methods: heat welding repair method through the soldering iron and other tools to repair, the performance of the insulation layer can be achieved to the level of intact cables, but the repair process is relatively complex, requiring operators to have a high level of technical skills. Personnel with a high level of technology.
