補強層の偏肉が生じる可能性はある。In addition, as a method for forming rubber or plastic cable connections, after applying an uncrosslinked insulation reinforcing layer on the cable conductor connections,
There is a method of housing this in a mold, injecting a heated and pressurized medium into the space around the cable conductor connection part in the mold, and heating and crosslinking the uncrosslinked insulation reinforcing layer with this medium (for example, (Special Publication No. 59-3834). however,
Even with such a method, since the medium is in a molten state when crosslinking the uncrosslinked insulating reinforcing layer, there is a possibility that uneven thickness of the insulating reinforcing layer as described above may occur.

An uncrosslinked insulating reinforcing layer 5 is formed by winding an uncrosslinked polyethylene tape on Ib. After this, cover this with the two-part mold 6 and 1. Epoxy resin or other thermosetting resin 7 is injected under pressure into the space around the uncrosslinked insulation reinforcing layer 5 inside the mold 6. Heater 8 built into the mold 6 or attached externally
The mold 6 is heated to heat and harden the thermosetting resin 7 first. After this, the uncrosslinked insulation reinforcing layer 5 is subsequently crosslinked.
