縁電線を製造することが行なわれてｖする。BACKGROUND ART Conventionally, a watertight compound is filled in the gaps between the strands of a conductor wire to form a watertight conductor, and an insulator is coated on the watertight compound to produce a watertight insulated wire.

るか。The methods for manufacturing this watertight conductor include: 1) Filling the cable conductor with a shelly-like mixture of curable liquid rubber when twisting the strands together; %1h Compound press-filling method: ■ A single thermoplastic resin such as polyethylene, ethylene-vinyl acetate copolymer, etc., or calcium chloride,
A composition containing a water-absorbing filler made of calcium oxide is extruded into a tape or string shape and wrapped together with conductor wires.

ありた。However, in method (2), since the sherry-like mixture is viscous, it must be heated and filled, which makes watertight work complicated, and the mixture in the finished product is not exposed to high temperatures.
- CR was easy to move.I had a drawback. Further, the curable liquid rubber has the disadvantage that the finished product does not flow or has a high viscosity of 1 hour at room temperature, making watertight work complicated. The method (2) has the disadvantage that the powder has a low viscosity and flows, making it difficult to connect the conductors. In addition, method (2) allows easy watertightness, but since the resin in the finished product is thermoplastic, it tends to flow due to heat, and the watertight effect at high temperatures is insufficient.

た。The present inventors have made extensive studies to improve these drawbacks, and found that if a water-absorbing swelling polymer is blended with an olefin polymer or a vinyl chloride polymer and the method (2) is carried out,
It was found that the water-tight work was easy and the water-tight effect at high temperatures was very good because it did not flow due to heat (%/h).
