通としている。[Detailed Description of the Invention] Conventionally, in a power cable made by twisting a large number of wire cores, for example, in the case of three cores, each center conductor is made of an insulated wire core with crosslinked polyethylene as an insulator, and They are usually twisted together, interposed with something like kraft paper, tied together, and covered with a sheath made of vinyl or the like.

する嫌いがある。At this time, the final binding for integration is performed using rubberized tape before covering the sheath. This is to prevent moisture absorption. However, in reality, although this rubberized tape does play a role in absorbing moisture, it is still not perfect, and there is still room for improvement in cases where strict moisture protection is required, and it also has the following disadvantages: is recognized. Namely, 1. Rubberized tape tends to have rubber scum attached to it during manufacturing operations, and if a sheath is extruded with this rubber scum still attached to the tape, the tape tends to have a lump-like appearance.
２、ゴム糊（有機溶剤Ｄを使用することで、加工工程が
有害業務となつている。2. Rubber glue (using organic solvent D makes the processing process hazardous).
３、テープ加工作業のスピードが糊引きの都合でｏ ア

も安いとはいい難く、総じて経済性が低い。3. The speed of tape processing cannot be increased due to the need for gluing, and the speed is limited to 10 to 20 m/cm at most, and the materials are not cheap, making it generally uneconomical.
本発明は、かかる諸欠点を一掃するもので、新提案は、

である。The present invention eliminates these drawbacks, and the new proposal is:
By eliminating such rubberized tape, a thermoplastic insulating material such as polyethylene/5-ethylene is melted and formed into a film, which is then integrally formed on a cloth using the T-shaped die method, and then processed. This was replaced by electrical insulation tape.

Then, on this circumference, polyethylene was melted and made into a film, and a T.
A composite insulating cloth tape 5 integrally formed on a cloth tape by a mold die method is wrapped. After that, the 30-stranded body was finally bound with the composite insulating tape 5, and then a thermoplastic plastic source 6 such as a vinyl sheath was applied by extrusion, and the heat generated during extrusion and application of the sheath was further applied. This is to fuse the wound layers of the tape 5 to each other.
