Electric layer, it is desirable to do not damage insulating layer and can be easily from insulation displacement.Therefore, it is intended that it is closely sealed well with insulating layer and
Can be easily from the external semi-conductive layer of insulation displacement during the end processing of power transmission cable.
For the base resin of the semi-conducting resin composition of external semi-conductive layer as formation, it is desirable to use for
Form the thermoplastic resin of the inexcessive adaptation closely sealed and that there is appropriateness of resin of insulating layer.
In patent document 1, the base resin as the semi-conducting resin composition for forming external semi-conductive layer, it is proposed that
Following base polymers, the base polymer include：Ethane-acetic acid ethyenyl ester containing 20~45 mass % of vinyl acetate
10~40 mass % of polymer blend of 60~90 mass % of copolymer (EVA) and cross-linked ethylene-propylene copolymer etc..
