Embodiment Construction

[0025] A method for repairing a thermoplastic sheathed cable described in an embodiment of the present invention comprises the following steps:

[0026] 1) Use a single-sided blade to remove the sheath that cannot be repaired at the defective part, and clean the part to be repaired. Be careful not to damage the braiding layer and insulating layer of the thermoplastic sheathed cable to expose the cable core when removing the defective part;

[0027] 2) On the thermoplastic sheathed cable, start to grind into a cone shape about 15mm away from the defective part, and clean the tapered part;

[0028] 3) Take a small piece of thermoplastic sheath material for repair (it can be taken from one end of the sheath cable to be repaired, avoid using different materials for repair), clean it and dry it;

[0029] 4) Adjust the heating device (you can choose a heat gun, adjust the gear of the heat gun to 7-8), turn on the power switch, and heat the thermoplastic sheath material for repair th...

Abstract

The invention relates to a method for repairing a thermoplastic sheath cable. The method comprises the following steps: removing a flaw part, and cleaning a to-be-repaired part; wearing down from a position which is about 15mm away from the flaw part to form a taper, and cleaning up the taper part; getting a section of thermoplastic sheath material for repair, and cleaning up the thermoplastic sheath material and drying; heating the thermoplastic sheath material for the repair; sticking the treated thermoplastic sheath material for the repair to the flaw part, and cooling the thermoplastic sheath material; cutting off excess parts, and polishing the repaired part; twining with a bandage and covering the repaired part; heating the twined repaired part, and cooling the repaired part when the color of the repaired part becomes into the color of the repaired cable; testing the quality of the repaired part, and repairing again if testing is not ideal. The method provided by the invention has the beneficial effects that the phenomenon that a mountain of work is increased due to the fact that the cable is laid again is avoided; the phenomenon that the whole cable is wasted due to a cable sheath is damaged is avoided; complicated equipment is not used during a whole repair process, and unnecessary production cost is not increased.

Description

technical field [0001] The invention relates to a method for repairing thermoplastic sheathed cables. Background technique [0002] After the ship cable is laid, the outer sheath often has appearance defects such as small holes, scratches, indentations, and breakdowns. In order to avoid heavy workload and cable waste caused by re-stretching, an excellent repair method is needed. Repair damaged cables. Of course, in addition to ship cables, other sheathed cables can also be repaired after they are damaged, instead of being scrapped and replaced directly, which can save a lot of sheathed cables and avoid unnecessary waste. [0003] Some of the existing repairing methods are complex in operation and need to be equipped with expensive repairing equipment, which increases the production cost; although some repairing methods do not need to be equipped with expensive repairing equipment, the repairing effect is not ideal. Contents of the invention [0004] The purpose of the pr...
