Cable sheath break repair method

This method is applicable to the local defects of the PVC insulation layer and the jacket layer of the wire and cable, allowing the repair, such as broken glue, pit, disjoint, wrinkle, bump, ear, edge wrap, breakdown, joint and so on.

The materials and equipment used are: Plastic strips, skins, blocks and tubes with the same plastic material. The raw materials should be smooth, clean and free of other defects. The instruments used are fine wood files, knives, scissors, pliers, screwdrivers, copper sheets, or flat, smooth cable paper. Hot-air plastic welding torches, soldering irons and welding torches for plastic welding have a power above 300W.

The specific local defect repair method is as follows:

1, breakdown point, hole, pit and other repair methods

The knife is used to trim the defects, and a plastic block of the same size and shape is cut into a 45-degree angle, placed on the repair area, fixed with a pliers or a screwdriver, and then continuously welded with a hot air speed welding torch, and compacted and pressed with a copper sheet. Tight, flattened. 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 is tested by the spark machine without breaking down to form a 45-degree slope in the defect area of â€‹â€‹the plastic layer. The plastic piece or strip with the same shape, color, and thickness is fixed with pliers or a screwdriver. After that, it was connected with a hot air speed welding torch, then compacted, pressed, and flattened with a copper foil. Finally, it was tested by a spark machine and it was not qualified for breakdown. The plastic defect is scraped with a knife, and the recessed part is filled with the same plastic strip under the action of a hot wind plastic welding gun, then flattened, pressed, and compacted with a copper piece at the defect repairing place, and the spark test is performed without breakdown. Qualified.

2. Repair method of big joint

1) Repair of general 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 clean, uniform in color and thickness, and the length and the outer diameter are the same as those in the broken glue. The plastic pipe is cut on the side of the pipe along the axis to an angle of 45Â° with each other, and it is placed on the broken rubber. The fine copper wire is equidistantly clamped, and then the same plastic bar is welded under the hot air welding torch. Welds are then welded and then compacted, pressed and flattened with copper. After the spark machine test does not breakdown is qualified.

2) Repair of large joints in the production process: In the production process, due to other reasons, it is temporarily parked and the sheath is disconnected. It can be continuously connected. The method is to cut the plastic sheath into a 45-degree-circle slope shape, withdraw it to the nose, extend it into the mouth of the mold core for 30mm, and then run the glue. After the glue is run, the crew members will cooperate with each other and drive. When the plastic layer is connected by hand, then plastic repair. 3) The quality of the cable jacket is longer than the length of one end of the cable. The other jacket is well-sealed and the length of the cable is fixed. It can also be used to repair large connectors in the production process. Only after removing the end cap with quality defects, select a larger die on the extruder. Press the process to squeeze the sheath on one end first. Gradually increase the traction speed at the large joint to gradually make the sheath at the interface. Thinned and covered on the original sheath cut into the slope shape, after the next machine and plastic repair.
