縁素線３間にシェリー７を充填した構造になりていた。FIG. 1 shows an example of a conventional sherry-filled electrical cable used as a waterproof communication cable or instrumentation cable system. That is, in the conventional Sherry-filled electric cousol, two or four insulated wires 3 with insulation 42 eroded around the outer periphery of the conductor 1 are twisted together to form a pair or wire 4, and a plurality of these are twisted. A cable sheath 6 is applied to the outer periphery of the cable core 5, and a shell 7 is applied between the pairs or forces within the cable core 5, between the pairs or forces, and between the insulated wires 3 forming the domes 4. It had a structure filled with.

った。However, in such conventional sherry-filled electrical cables, there is a difference in the dielectric constant of Beso Ely (1" of air 1.0% Sherry's # ff 2.1 ~2.2
) has the disadvantage that the capacitance within the pair or force increases. In addition, in the conventional sherry-filled electrical cable, the insulating layer 2 of the insulated wire 3 is swollen with sherry during long-term use, deteriorating the electrical properties of the cable, and the swelling is accompanied by the addition of sherry into the insulating layer 2. However, there is a drawback that various deterioration inhibitors are extracted onto the surface of the insulating layer 2 and the life of the insulated wire 3 is shortened.

0 examples are shown. This bulk insulated wire 8 has a structure in which two or four conductors 1 are built in a bulk insulator 9 with a circular cross section and are in good condition at equal intervals in the circumferential direction and twisted at a predetermined length in the longitudinal direction. It has become. The bulk insulator 9 may be polyethylene or solid glass such as polyethylene.
Alternatively, a foamed glass such as foamed tetraethylene can be used alone or in combination in a layered structure.

You can. In addition, since the shelly 7 is attached only to the surface of the bulk insulator 9, the contact area between the shelly 7 and the insulator is significantly smaller than that of conventional pairs or ridges, which suppresses swelling of the insulator. be able to. Therefore, deterioration of the electrical characteristics of the cable can be prevented and the life of the cable can be extended.

There is no intervention, and therefore, it is possible to suppress the increase in capacitance even though it is Shelley's Sicaple. In addition, since the shelly is attached only to the surface of the bulk insulator, the contact area between the shelly and the insulator is significantly smaller than that of the conventional pair or force, and swelling of the insulator can be suppressed. can. Therefore, deterioration of the electrical characteristics of the cable can be prevented and the life of the cable can be extended. Further, according to the present invention, the amount of sherry to be filled is smaller than that of the conventional method,9, thereby saving resources and reducing costs.
