A watertight material is filled between the strands to be twisted, and a second watertight material extruder 4 is arranged on the inlet side of a second 12-strand twisting machine 3 installed in series with the twisting machine 1. Similarly, watertight material is filled between the wires. Cemented carbide and wooden twisting dies 5 and 6 are installed on the exit side of each of the first and second stranded wires (1 ml, 3) in order from the exit side of the stranding machine, so as to form the stranded wires. It has become.

A burner 7 is arranged on the outlet side of each wire twisting machine 1.3, and the watertight material is heated with gas to soften it in order to make the twisted wires tighter.

In addition, the flame directly hits the copper wire and watertight material, causing discoloration of the copper wire.
There are disadvantages in that the watertight material tends to deteriorate and the workability of gas ignition, extinguishing, etc. is not good.

In the watertight electric wire manufacturing method, the strands forming the inner layer and the strands forming the outer layer are assembled using a wooden twisted rodice, and then a cemented carbide twisted rodice heated with hot oil at 100 to 200°C. The feature is that the appearance is molded by

温度を±５℃の範囲でコントロールできる。By doing this, the watertight material is heated at a constant temperature compared to conventional manufacturing methods, which improves the adhesion between the inner and outer eyebrows, and the strands come into close contact with each other, so the watertight material is heated evenly. A watertight electrical wire with excellent watertightness can be obtained. Also, by using hot oil, the heating temperature of the watertight material can be controlled within a range of ±5°C.
