Cable Connector Troubleshooting
Before cutting the joint, check whether there is water and moisture in the joint. If there is, do not use a blowtorch to cut the joint, because the blowtorch heats the moisture from both sides of the joint to the inside of the cable. It is best to use a hammer and cut. Cut the casing with a knife; if there is no moisture and moisture, you can use a blowtorch to scald the lead sleeve, remove the lead sleeve dirt, scrape off the rust spots, remove the solder slag, and remove it from the cable connection for reuse.
To remove moisture, the baking method can be used. It is baked with a blowtorch or charcoal to drive out moisture. This method can only be used in small amounts of moisture. When the paper insulated core wire is seriously damp, the wax pouring method can be used to remove the moisture with hot wax. It is made by mixing 60% white wax and 40% neutral vaseline and heating it to 130~140℃. When pouring the wax, it is controlled at 120~130℃. The wax is poured from the cable lead sheath on both sides of the incision 10~15cm. The sleeve starts, and gradually moves to the incision. After the wax material condenses at the incision, pour it to the center of the joint until there are no air bubbles and dipping sounds on the core line.
If the above two treatments still have residual moisture in the cable joint, which cannot be completely removed at that time, use the silica gel drying method to further remove the moisture, that is, put an appropriate blue silica gel desiccant in the connector, and then seal the soldering lead casing. The residual moisture of the core wire will be slowly absorbed by the silicone, and the insulation resistance of the core wire will gradually increase.
