Problems solved by technology

However, during the removal process, the dry compressed air filled in the cable will leak, causing water vapor to enter the cable
Especially for pipeline cables, during the dismantling process, the accumulated water in the pipeline will enter the cable, which will reduce the insulation strength of the cable to the ground, making it impossible to reuse, and the phenomenon of waste is serious, thus increasing the cost of telecom operators

Embodiment Construction

[0017] Firstly, inspect the old cables to be removed to judge their repairability;

[0018] Then use special equipment to strip the outer sheath of the cable that can be repaired;

[0019] After that, use the cable splitting device to split the large logarithmic cable into multiple small logarithmic cables;

[0020] After that, the cable core of the small logarithmic cable is reinforced to prevent the structure of the original cable core wire from being damaged and affecting the performance;

[0021] Afterwards, the polyester tape is re-wrapped using a cable wrapping machine;

[0022] After that, use a fully automatic cable detector to detect whether the cable core is broken, mixed lines and line resistance;

[0023] After that, use the cable sheathing machine to longitudinally wrap the aluminum-plastic composite tape on the cable core with no breaks, mixed wires, and qualified cable resistance;

[0024] Finally, the outer sheath is extruded using a cable sheathing machine ...

Abstract

The invention discloses a cable retreading method, specifically a cable retreading method for retreading a used cable into a usable cable, in particular suitable for retreading of a communication cable. The method comprises following steps: detecting the used cable to be detached, and determining the repairable degree; stripping off the outer sheath of the repairable cable; dividing the large-pair cable into a plurality of the small-pair cables; strengthening the core of the small-pair cables to prevent the performance of the cable from being influenced by the damaged core structure of the prior cable; re-coating with a polyester tape; detecting the connection state of the cable core, the cable mixing condition, and the interline resistance; longitudinally covering the cable core without disconnection and mixing condition and having the qualified interline resistance with a aluminum-plastic composite tape; and extruding to manufacture the outer sheath to obtain the retrodden cable. The method can be used for retreading the used cable and can reduce the cost of a telecom operator.

Description

technical field [0001] The invention relates to a cable production method. Specifically, it is a cable refurbishment method for refurbishing old cables into usable cables, especially for the refurbishment of communication cables. Background technique [0002] It is known in the cable manufacturing industry that after the communication cable is laid, its service life is relatively long if it is not for human behavior. However, with the expansion and reconstruction of the road, the original good cables need to be moved or diverted, so many used cables will be removed. However, during the removal process, the dry compressed air filled in the cable will leak, causing moisture to enter the cable. Especially for pipeline cables, during the dismantling process, the accumulated water in the pipeline will enter the cable, which will reduce the insulation strength of the cable to the ground, making it impossible to reuse, and the waste phenomenon is serious, thus increasing the cost...
