A method to overcome cable leakage

Abstract

The invention discloses a method for overcoming cable leakage in the technical field of digital communication. The method comprises the following specific steps: using flexible materials to lap and wrap in a cabling process; and using a dual-longitudinal-wrap mold to longitudinally wrap aluminum tapes and using the flexible materials to lap and wrap at the same time in a sheathing process. The mutual cooperation by using the different cladding modes can be utilized to eliminate the cladding dead area caused by the leakage resulting from using the flexible materials to lap and wrap, thus improving the cladding quality. Meanwhile, the auxiliary positioning of a longer conduit and a stable cable core can be used for avoiding the phenomenon that the longitudinal-wrap mold damages the cable core due to the trembled cable core before the longitudinal wrapping. The method is improved in the original technology of the communication cable, so the method has the advantages of being simple in processes, convenient to operate, economic and practical, obvious in effect and the like, and can be applied to digital communication cable industries widely.

Description

technical field [0001] The invention belongs to the technical field of digital communication cable manufacturing, in particular to a method for overcoming cable leakage. Background technique [0002] At present, the production process of local communication cables is very mature. The conductors are drawn, annealed, preheated, extruded to form a single wire, and twisted to form a pair of wires. There are two processes for covering the cable core with a flexible material when forming a cable. Tape-wrapped cable core, the other is the flexible material wrapping the longitudinally-wrapped cable core and then binding to ensure the longitudinal wrapping effect, and finally the aluminum strip longitudinal wrapping and sheath. The first process, in the process of wrapping the flexible material, due to the instability of the wrapping tension and the tension of the take-up and take-up line, it is easy to leak the bag, so that it is easy to cause scratches, damages, etc. when the alumi...

[0006] 3) Adjust the relative distance between the outlet of the longitudinal wrapping die of the flexible material and the joint of the longitudinal wrapping die of the aluminum strip to 2mm-5mm, that is, the longitudinal wrapping of the flexible material is within a very short distance of 2mm-5mm from the mold, and the longitudinal wrapping is not In the open state, it is compressed and shaped by aluminum tape longitudinally, so as to overcome the leakage phenomenon caused by the excessive distance between the two molds. When the flexible material tape is fully covered, it can effectively eliminate objects such as cable cores and molds. Mixed wires, damaged wires, and unqualified insulation caused by friction;
