●Outline of the device Figure 1 shows an outline of the device used to carry out this invention. A cooling device 14 is provided between the end of the cable conductor 12 from which the copper oxide film is removed and the cable 10.
will be established. As this cooling device 14, for example, a heat pipe 16 can be used. In that case, one end 18 is made into a ring shape to surround the cable conductor 12, and that part absorbs the heat of the cable conductor 12.
Further, a fin 20 is attached to the other end so that heat is radiated from that part. When the heat pipe 16 is used in the cooling device 14 in this way, there is an advantage that the device is simple because there are no moving parts. However, other known cooling devices 14 may also be used. The entire portion of the end of the cable conductor 12 from which the copper oxide film is to be removed is surrounded by a container 22, and the container 22 is provided with a gas inlet 24 and an outlet 26. Also provided is an induction heating coil 28 for heating the cable conductor 12, for example. ●Removal of copper oxide film (1) First, the cable conductor 12 is
When the cable 10 is cooled and the conductor is heated,
Prevent the cable insulation from being harmed by the heat transmitted to the cable. (2) A reducing gas (hydrogen gas, etc.) is flowed into the container 22 from the inlet 24, and the portion of the cable conductor 12 from which the copper oxide film is to be removed is uniformly heated in the gas by the induction heating coil 28. Heat. Then, the copper oxide film of the wire insulation is reduced to copper, and the insulation film disappears. The heating temperature at that time is about 150 to 500°C, and the heating time is about 10 to 20 minutes. (3) When the copper oxide film is gone, stop feeding the reducing gas. Instead, inert gas is supplied to the inlet 24.
The gas in the container 22 is replaced with an inert gas, and then the heating of the cable conductor 12 is stopped. (4) After that, the inert gas cooled to room temperature or below continues to flow into the container 22 to slowly cool the cable conductor 12. The cable conductor 12 is then cooled to a temperature at which no oxidation reaction occurs even when exposed to air. Until then, the pressure of the inert gas in the container 22 is always kept above atmospheric pressure so that the cable conductor 12 does not come into contact with the air. Cooling by the cooling device 14 continues until the temperature of the cable conductor 12 falls to a level that does not harm the cable insulation.

(1) In the case of the stranded wire conductor that is the subject of the present invention, the reaction of the inner layer strands is slower than that of the outer layer, and the copper oxide film is about 1 μm thick and strong, so the entire cable conductor is The copper oxide film on the wire does not immediately change to copper. However, in the case of the present invention, the entire portion of the cable conductor from which the copper oxide film is to be removed is placed in a reducing gas and heated uniformly, so that the reduction reaction occurs almost in all the strands of the cable conductor. Proceed evenly. Further, the reduction can be carried out for the required time and after confirming that the copper oxide film has completely disappeared, the next step can be carried out. (2) Since the part of the exposed cable conductor next to the cable insulator is cooled, the heating of the cable conductor during the reduction of the copper oxide film does not have an adverse effect on the cable insulator, and even after heating is stopped. By continuing cooling, cooling of the cable conductor can be promoted. Generally, cable conductors that are insulated are large in size and have a large heat capacity, so it takes time to cool them down. Speeding up the cooling reduces the amount of time the inert gas continues to flow, which saves material and time. (3) Since it is a completely dry method that does not use an aqueous solution, there is no negative impact on the cable.
