により。(Prior art) As shown in Fig. 1, a normal steel core aluminum stranded wire 1' has a steel stranded wire section 3' (1) in which steel cable wires 2' having a round cross section are twisted together, and a steel stranded wire section 3' (1) with a cross section on the outer periphery. It consists of an aluminum stranded wire part 5' made by twisting together round aluminum wires 4', and the tension is mainly shared by the steel stranded wire part 3', and the current is shared by the aluminum stranded wire part 5'. ing. When such steel-core aluminum stranded wire 1' is stretched between steel towers, as shown in FIG. 7. Gold wheel 8 hanging from a steel tower (not shown)

部３′と接する側のアルミ素線４′が大きい。In a normal steel core aluminum stranded wire 1', both the steel stranded wire part 3' and the aluminum stranded wire part 5' are strands 2't4 having a round cross-sectional shape as described above.
Since the steel strands 3' are formed by being twisted together,
The contact between the aluminum stranded wire portion 5' and the aluminum stranded wire portion 5' is point contact. Such a steel core aluminum stranded wire 1' is connected to a large number of metal wheels 81+81.
. . 8n, there is a drawback that the aluminum wire 4' is deformed on the side in contact with the metal wheel 8, as shown in FIG. 3 (2). In particular, the deformation of the aluminum wire 4' is large on the side of the aluminum wire 4' that is in contact with the steel stranded wire portion 3'.

って圧縮接続されたアルミスリーブである。The amount of deformation of the aluminum wire 4' is approximately proportional to the wire length (L), so in order to keep the mechanical performance of the steel core aluminum stranded wire 1' within an acceptable range, the wire length should be The length (L) is about 5 km or less. For this reason, it has the disadvantage of requiring a large installation area and multiple installation locations for the drum and take-up machine.As the strands and aluminum strands, the fan-shaped copper strands 2 and the fan-shaped aluminum strands have a fan-shaped cross section. 4 is used to make the surfaces of the steel stranded wire part 3 and aluminum stranded wire part 5 low tide, and the contact between the strands is surface contact.The segmented steel core aluminum stranded wire 1
You can use However, in such a segment type steel core aluminum stranded wire 1, when connecting a retaining clamp or the like, the aluminum strand portion 5 is stripped off at the tip of the segment type steel core aluminum strand 1 as shown in FIGS. 5 and 6. Even if the copper sleeve 11 is compressed and connected as shown, the steel stranded wire portion 3' of the ordinary steel core aluminum stranded wire 1' is
The steel sleeve 11 is compressed and connected to the steel sleeve 11.
Since the biting part 11A is not formed, sufficient friction between the steel stranded wire part 3 and the steel strip IJ-b 11 is not generated, and in order to hold the segment type steel core aluminum stranded wire 1, as shown in FIG. The drawback was that it required a large retaining clamp. In FIG. 9, the clevis part integrated with the 12-bar steel sleeve 11,
Reference numeral 13 denotes an aluminum sleeve which is compressed and connected across the aluminum stranded wire portion 5 and the steel steel IJ-7'll.

供することができる。(Effects of the Invention) As explained above, the segment type steel core aluminum stranded wire according to the present invention is formed by twisting strands of fan-shaped cross section, so that the mutual contact between the strands is a surface contact. Moreover, there is almost no deformation of the aluminum wire during wire drawing, and the P1 wire length is longer than that of conventional steel core aluminum stranded wire (for example, 20 km).
It can be done to a certain extent. ), which can reduce the required number of vast drum installation locations. especially,
According to the present invention, each corner of the outer peripheral side of each steel cable wire having a fan-shaped cross section constituting the outermost layer of the steel stranded wire is provided with a rounded portion having a radius of 1 min or more, and the steel stranded wire portion is attached to the rounded portion. Since the surface of the outermost layer is provided with multiple grooves for biting compressed material, when compressed material such as steel sleeve is compressed and connected, the compressed material will be sufficiently bitten into each groove, and the compressed material will be fully inserted. It can be held back. Therefore, according to the present invention, it is possible to achieve both the deformation prevention effect of the aluminum wire, which was difficult to achieve in the past, and the sufficient retention effect of the compressed material on the steel stranded wire portion, which is very suitable for practical use. It is possible to provide a segment type steel core Alzu stranded wire.
