<p><P>PROBLEM TO BE SOLVED: To solve a problem that a pre-mold rubber insulated cylinder which is used for connecting cables such as conventional CV cables or the like is formed of an inner semi-conducting layer, an insulation layer and an outer semi-conducting layer, and for production of which a mold die is necessary for each layer because of its structure, as a result production takes long and its production cost is increased. <P>SOLUTION: The cylindrical pre-mold rubber insulated cylinder comprising a plurality of layers formed of a rubber material as base is characterized in that sheet-like electrodes in cross section are formed of the semi-conductive rubber layer as inner side and a high permitivity rubber layer thereon at the center of the inner surface and at the opposite ends of the pre-mold rubber insulated cylinder. <P>COPYRIGHT: (C)2003,JPO</p> |
