If the cable is used for a long time or no corresponding maintenance measures are taken, the surface of the cable will be damaged; the wire and cable maintenance personnel are required to perform certain repairs. The frequently occurring situations are: broken rubber, pits, out of joints, wrinkles, bumps, Ears, edges, breakdowns, joints, etc.
First, the Thai cable
The commonly used cable repair materials and equipment for repairing cable raw materials include plastic strips, skins, blocks, and tubes. The specific materials are required to be smooth, clean, and free from other defects.
The instruments used are fine wood files, knives, scissors, pliers, screwdrivers, copper sheets, and cable paper. Hot-air plastic welding torches, soldering irons and welding torches for plastic welding have a power of 300W or more.
Second, the partial defect repair method
1. Breakdown points, holes, pits and other repair methods began to use a knife to trim the defects, and cut into a plastic block with a uniform 45-degree-angle slope shape, fixed with pliers or a screwdriver on the repair area, and then use heat The wind speed welding torch is continuously welded and compacted, pressed and flattened with copper sheets. When welding plastic, pay attention to the hot air temperature of the welding torch not too high, so as not to repair the plastic scorch at the repair site. The repaired defect was tested by the spark machine and was not qualified for breakdown.
2. Repair methods such as broken glue, cracks, dents, and holes should be cut at a 45° angle in the repaired part, and plastic blocks or strips of the same shape, color, and thickness should be secured with a pair of pliers or a screwdriver. The wind speed welding gun is connected, then compacted, pressed, and flattened with a copper piece, and finally tested by a spark machine, and it is not qualified for breakdown.
3. Ears, projections, ribs, pleats, etc. The plastic defect is scraped with a knife. The recessed part is filled with the same plastic strip under the action of a hot wind plastic welding gun, and then flattened with a copper sheet at the defect repair site. , compaction, compaction, after the spark machine test, no breakdown is qualified.
4. Repair method for large joints Repair of conventional large joints: cut both sides of the broken plastic with a knife on the plastic layer along the circumference to form a slope with a 45 degree angle, take a clean, consistent color and thickness, length and outer diameter The same plastic pipe at the broken end of the plastic is cut along the axis of the pipe to an angle of 45° with each other and is placed at the broken end. The fine copper wire is equidistantly clamped, and then the same plastic strip is used in the hot air welding torch. Under the welding, the bonding welding is good, and the copper sheet is used for compaction, compression and flattening, and the spark test is not qualified for breakdown.
