ている。(Technical background of the invention and its problems) In recent years, with the increase in electricity demand,
Development of OF cable is being promoted. In such ultra-high voltage OF cables, using cellulose fiber paper alone such as conventional kraft paper has a large dielectric loss and is problematic for long-distance power transmission cables, so high-density polyethylene and polypropylene are used. The use of laminated insulating paper, which is made by pasting kraft paper on one or both sides of a polyolefin plastic film, is being considered.

It is being done.

部が得られないという問題があつた。 However, in this connection method,
The dielectric constant ε of laminated insulating paper is 2.5 to 2.8, while that of laminated paper is 3.3 to 3.7, which is considerably larger, which disrupts the electric field at the interface between the cable insulation layer and the reinforcing insulation layer, resulting in poor electrical properties. There was a problem that the cable connection was not available.
