却が必要とされていた。As a cooling method for CV cables, the evaporative cooling type stores the three-phase CV cable and refrigerant pipes for transporting liquid refrigerant all together in a steel pipe, and cools the CV cable by filling it with evaporative refrigerant under pressure. A CV cable system is optimal. On the other hand, the joint steel pipe that stores the joint has a larger diameter than the cable steel pipe that stores the CV cable, and the bulkhead plate that allows the evaporative refrigerant to pass through is not included.
At the stop connection, the flow rate of the refrigerant slows down due to the large diameter (due to the large diameter), and evaporation of the refrigerant occurs, causing local CV blue or temperature rise at the connection. , the cooling force (9) was required to completely reduce the effect of this part.

A connecting portion 6 of the CV cable 1 is housed in the housing. There is a liquid τ around this connection part 6L and the CV cable l near it.
A platform layer 7 is installed. This liquid permeable layer 7 is made of a material that easily absorbs the liquid of the evaporative refrigerant 4, and is made of a material that easily absorbs the liquid of the evaporative refrigerant 4.
Nonwoven fabrics in the form of sheets or tapes, lurose paper, liquid swelling resin, glass fibers, plastin paper, and the like are used. Liquid permeable layer 7d: Absorbs the liquid of the evaporative refrigerant 4 in the connecting steel pipe 5, and increases the temperature determined by the evaporation pressure in the hexagonal metal connecting steel pipe 5 of the CV cable 1 in the connecting part 6 and its vicinity. ) W. In this way, the inside of the connecting steel pipe 5 is kept at a constant temperature by the liquid 8 permeable layer 7, so that local temperature rise is prevented. In addition, connection part #4fJS
