What If The Cable Insulation Sheath Is Damaged?

When the cable insulation sheath is damaged, we can carry out on-site maintenance. After all, the cost of re manufacturing the cable connector is relatively high. Then how to repair it? Here are the following methods.

The specific repair method is to repair the defects with a knife, cut the edge into a 45 ° angle slope shape, place the plastic blocks of the same size in the repair area, fix them with pliers or screwdriver, then use a hot air speed welding gun for continuous welding, and use copper sheets to compact, compress and flatten them. When welding plastic, pay attention that the temperature of hot air for welding torch shall not be too high to avoid burning of plastic at the repair site. The repaired defect shall be tested by spark machine and shall be qualified if it does not break down. The cable manufacturer reminds you that the plastic used should be consistent with the cable insulation material as much as possible, and the thickness should also be consistent with the cable insulation, and it can only be thicker than the cable insulation. If it is too thin, there is still a risk of breakdown. The hot air temperature of the welding gun should not be too high to avoid the plastic burning at the repair site. Before repair, make sure to eliminate the factors that damaged the cable before, otherwise the cable will still be damaged again in the same way.

The repair method is not a permanent solution to the cable damage due to quality problems. Therefore, if the cable is damaged due to quality problems, it is recommended to directly replace the cable with quality assurance.
