いる。[Prior Art] A high-voltage, medium-voltage, or low-voltage overhead power transmission system has a ground wire (overhead ground wire) held at a ground potential at the top thereof. Conventionally, this ground wire is a stranded wire made by twisting multiple strands of aluminum coated steel wire or aluminum alloy wire, which has a steel wire as a core material and coats aluminum around the steel wire. used in

。このような、グランドワイヤの素線の溶断事故による
被害は山岳地域において甚大である。However, the problem is that the ground wires of conventional overhead power transmission systems are susceptible to damage from lightning strikes. In other words, ground wires are susceptible to lightning strikes, and if they are struck by lightning, the impact force of the arc may cause the wires to break, or the heat may cause the aluminum-coated steel wire or aluminum alloy wire of the wire to melt. occurs. In extreme cases, the number of disconnected or fused wires is large, and the wires may have to be replaced. Damage caused by such melting accidents of ground wire strands is severe in mountainous regions.

案されている。By the way, as mentioned above, wire breakage occurs due to the impact force of the arc and the melting of the wire due to the electric current, so in order to eliminate wire breakage caused by these factors, a high temperature coating is applied to the surface of the core wire made of aluminum or aluminum alloy. Wires coated with materials having a high melting point and high strength, such as iron-based materials, have been proposed.

等の層をめっき形成して、耐食性を高めている。As the iron-based material, conventionally used steel materials are iron-carbon steel, which is ferritic at room temperature, or 5US304 stainless steel, which is austenitic at room temperature. In addition, when used in power transmission lines, it is necessary to consider contact corrosion with other component wires and corrosion resistance in the atmosphere, so the surface of the iron-based coating material is further plated with a layer of aluminum or zinc. formed to improve corrosion resistance.

耐雷電線用素線が製造される。In this case, when manufacturing the strands, the above-mentioned iron-nickel alloy sheathing material is applied vertically to the core wire, the sheathing material is bent around the core wire to form it into a pipe shape, and the ends are attached in the longitudinal direction of the core wire. Weld and fix along. Thereby, the core wire is covered with the covering material. Next, a step of performing diameter reduction processing and heat treatment,
A strand for a lightning-resistant electric wire is manufactured through a step of forming an aluminum or aluminum alloy layer or a zinc or zinc alloy layer on the surface of the coating material.

It is necessary that the coating material does not lose its cold workability and toughness even when subjected to heat treatment at a temperature of 00°C.

になるという問題点がある。[Problems to be Solved by the Invention] However, since the wire sheathing material used in conventional lightning-resistant electric wires is made of iron-carbon steel or stainless steel, the above-mentioned characteristics (1) and (2) are not satisfied. It is enough. For this reason, when strands for lightning-resistant electric wires are industrially produced in large quantities, they have the disadvantage of low productivity due to the presence of many defects and the occurrence of wire breaks. Further, when manufacturing a stranded wire by twisting strands together, defects such as cracks are likely to occur in the strands during this stranding process, and when these cracks occur, the wire becomes unusable.
本発明はかかる問題点に鑑みてなされたものであって、

The purpose of the present invention is to provide strands for lightning-resistant electric wires with excellent productivity and quality stability.

The core material is copper or a copper alloy, and the core material is covered with a coating material made of an iron-nickel alloy. This iron-nickel alloy coating material has the advantage that it has excellent cold workability as described above among iron-based materials that have excellent lightning resistance, and its properties do not deteriorate due to heat treatment.

%以上にする必要がある。In order to have such excellent properties, the total content of iron and nickel in this coating material must be 80% by weight or more. Chromium may be added to this iron-nickel alloy from the viewpoint of improving corrosion resistance, and manganese, cobalt, or molybdenum may be added from the viewpoint of improving strength. However, these additive elements may deteriorate the workability of the iron-nickel alloy. Therefore, in order to ensure sufficient workability, it is necessary to make the amount of these elements added less than 10% by weight and to make the total content of iron and nickel 90% by weight or more.

十分な特性が得られない。Further, the amount of nickel added is 2 to 65% by weight. In order to improve the workability of the coating material, it is necessary to add 2% by weight or more of nickel. If the nickel content is less than 2% by weight, sufficient characteristics such as toughness cannot be obtained even if manganese, which is also an austenitizing element, is added as another third element.
更に、ニッケルを65重量%を超えて添加しても、その

As a wire for lightning-resistant electric wires, the manufacturing cost becomes unnecessarily high and it is wasteful. For this reason, the nickel content is set at 2 to 65% by weight.

覆材の断面面積比率は5乃至50%に設定する。Furthermore, the coverage rate of the iron-nickel alloy coating material is the cross-sectional area ratio to the overall cross-sectional area consisting of the core material and the coating material,
Set it to 5 to 50%. Usually, this wire is made by longitudinally attaching a tape made of a material constituting the sheathing material to a wire rod made of aluminum or its alloy, copper or its alloy as a core material, and continuously forming the tape into a pipe shape.
It is manufactured by welding and fixing the joint ends. After the composite wire is fixed by welding as described above, it is reduced in diameter to a predetermined diameter to integrate the covering material and the core material, and is then heat treated under appropriate conditions. In this way, the sheathing material is usually formed into a pipe shape and then welded, so if a tape with a thickness such that the cross-sectional area ratio of the iron-nickel alloy sheathing material is less than 5% is used, the tape will The thickness is too thin, making welding difficult. Moreover, if the thickness of the iron-nickel alloy coating material is too thin, it will not be able to provide the lightning-proofing effect inherent to the coating material. On the other hand, if the thickness of the iron-nickel alloy coating exceeds 50% in terms of cross-sectional area ratio, the tape becomes too thick and difficult to form into a pipe shape. Therefore, the cross-sectional area ratio of the covering material is set to 5 to 50%.

る。Furthermore, in order to avoid contact corrosion with other constituent wires of the iron-nickel alloy coating material and corrosion in the atmosphere, if a layer of aluminum or aluminum alloy is formed on the surface of the coating material, , its thickness should be 1.0 mm or less. On the other hand, when forming a layer of zinc or zinc alloy on the surface of the coating material, the thickness thereof should be 0.5 mm+ or less. This is because aluminum, zinc, or an alloy thereof in the outermost layer of the strand essentially deteriorates the lightning resistance of the strand, so it needs to be formed sufficiently thin.
このため、耐雷性を劣化させない範囲として、防食用最
外層の厚さをその材質に応じて上記範囲に設定する。For this reason, the thickness of the outermost layer for corrosion protection is set within the above range depending on the material thereof, so as not to deteriorate the lightning resistance.
