径が設計値より太径とがっていた。The fan-shaped conductor of the electric cable is 120 degrees in the case of 3 cores,
In the case of 4 cores, it is formed into a 90 degree fan shape. and,
After the surface of the fan-shaped conductor is coated with insulating paper, the cable is formed by twisting a plurality of conductors into a twisting machine to have a circular cross section. When wrapping insulating paper around this fan-shaped conductor, the insulating paper is wound along the shape of the conductor, but the more the insulating paper is wrapped around the fan-shaped conductor, the more circular the core shape becomes. This phenomenon appears particularly in the part corresponding to the twisted contact surface of the conductor. This was the main cause of the excessive twisting outer diameter. That is, the apparent thickness of the insulation is the thickest at the part of the twisting contact surface, and this part mainly makes contact, thereby preventing full-surface contact and causing the outer diameter of the twisting part to be larger and more pointed than the designed value.

ものである。The present invention was made in view of the above situation, and the outer diameter of the cable after twisting a plurality of sector-shaped conductors into a cable is
It is an object of the present invention to provide a fan-shaped electric cable conductor that can prevent the conductor from becoming too large due to insufficient contact at the conductor contact surface.

る。In the electric cable fan-shaped conductor of the present invention, a conductor is formed to have a fan-shaped cross section, and after being insulated, a plurality of conductors are twisted together to form a cable, and a longitudinal direction is attached to the central part of the fan-shaped twisted contact surface of the conductor. A concave portion is formed in the groove.

互の接触面９に長手方向に凹状部８が形成されている。An embodiment of the electric cable fan-shaped conductor of the present invention will be described below with reference to FIGS. 1 and 2. Figure 1 is a cross-sectional view of a sector-shaped conductor.
FIG. 2 is a sectional view of a main part of the compression roll for forming a conductor shown in FIG. 1. In FIG. 1, l is 1200, that is, three stranded fan-shaped conductors, and a concave portion 8 is formed in the longitudinal direction on the mutual contact surface 9 when twisted into a cable.

By compressing the conductor, the conductor 1 having the concave portion 8 can be easily formed.

多数回にわたる実験の結果はきわめて良好であった。Insulating paper (not shown) is placed around the outer periphery of the conductor 1 formed in this way.
The three conductors are then twisted into one cable using the twisting machine shown in FIG. In FIG. 3, 4 is a die, 5 is a wire, 6 is a bobbin, 7 is a cage, and 1] is a roll. When the cable is twisted 9 and the concave portion 8 is formed on the contact surface 9 of the conductor l, the outer diameter of the cable does not increase even if an insulating coating is applied, and the cross section of the cable The space factor of the conductor l is improved. That is, after wrapping the insulating paper, the contact surface 9 is unlikely to be rounded, and adjacent conductors 1 come into contact over the entire contact surface 9, which makes it difficult to conduct multiple experiments with aluminum and copper conductors 1. The results were very good.

きる効果を有するものである。As described above, in the electric cable fan-shaped conductor of the present invention, a concave portion is formed on the contact surface of each sector-shaped conductor, so when a plurality of conductors are twisted together to form a cable, the contact surface of the conductor is This is effective in preventing the cable outer diameter from becoming too large due to insufficient contact between the contact surfaces, since it is possible to make uniform contact over the entire surface, rather than just the middle portion being in contact.
