る。(Technical background of J# Ming and its problems) In recent years, with the increase in electric power requirements, the development of OF cables of several 100 kV class is being promoted. In such ultra-high-voltage OF cables, conventional cellulose fiber paper such as kraft paper is used, which has a large dielectric loss and is problematic as a long-distance power transmission cable, 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.

ース繊維紙全巻回することが行なわれている。When using such laminated insulating paper, in order to prevent the laminated insulating paper from deteriorating due to the heat generated during lead work, it is necessary to wrap the whole layer of thin cellulose fiber paper over the wound layer of laminated insulating paper. It is being done.

紙巻回層間に跨って巻回することが行なわれている。By the way, when connecting such an OF cable, it is possible to wrap the same insulating paper as the laminated insulating paper that makes up the entire insulating layer of the cable on the conductor connection part as a reinforcing layer, spanning between the fiber paper wrapping layers of the cable on both sides. It is being done.

という問題があった。The dielectric constant ε of laminated insulating paper is 2.5 to 2.8, while that of kraft paper is quite large at 3.3 to 3.7, so the electric field at the interface between the cable insulation layer and the reinforcing insulation layer is There was a problem that cable connections with good electrical characteristics could not be obtained.

In the figure, first, the conductors 2 exposed by peeling off the ends of a pair of OF cables 1 to be connected are connected to each other using a full connection sleeve 3. Next, of the insulating layer of the OF cable 1, only the portion covered by the reinforcing insulating layer (to be described later) is extended from all ends of the outer relatively thin kraft paper wrapping layer 4.
Then remove the wound layer 5 of laminated insulating paper (kraft paper completely welded to both sides of the polypropylene film).
expose. As shown in FIG. 1, a reinforcing insulating layer is formed by winding the reinforcing insulating paper over the conductor connection sleeve 6 in a spindle shape across a pair of laminate insulating paper wrapping layers 6 in which the same type of laminate insulating paper as the cable insulating layer is exposed. 7'.
