Abstract: An aluminum electrical wire includes a conductor including aluminum-based core wires, and an insulating resin covering covering the conductor and having a thickness deviation of not less than 70%. The aluminum-based core wires contain 99 mass % of aluminum, and the conductor is constructed by concentrically twisting 19 or 37 of the aluminum-based core wires at the same pitch in a non-compressed state such that the aluminum electrical wire has a current capacity that is substantially the same as a current capacity of a copper electrical wire having a diameter that is substantially the same as a diameter of the aluminum electrical wire.

Abstract: A conductor including multiple aluminum-based core wires, and an insulating resin covering directly covering the conductor such that the insulating resin covering is in contact with the aluminum-based core wires. The aluminum-based core wires includes one aluminum-based core wire containing not less than 99 mass % of aluminum in a center of the conductor and aluminum-based core wires positioned concentrically from the center of the conductor, and the conductor is constructed by concentrically twisting 19 or 37 of the aluminum-based core wires in a non-compressed state and at a same pitch such that a thickness deviation of the insulating resin covering is not less than 70%.

Abstract: The purpose of the present invention is to provide an aluminum wire in which the electroconductivity is similar to that of an insulated wire having a copper conductor, and in which the wire outside diameter is not increased. An aluminum electrical wire (1, 1A) in which an aluminum conductor (10, 10A) comprising 37 or 19 aluminum-based core wires (20, 20A) containing at least 99 mass % of aluminum is coated by an insulating resin covering (30), wherein the aluminum conductor (10, 10A) is obtained by concentrically twisting the aluminum-based core wires (20, 20A) in a non-compressed state, the cross-sectional area of the aluminum conductor (10, 10A) is 2.5 mm2 to less than 17 mm2, and the insulating resin coating has a thickness equal to from 10 to 20% of the conductor outside diameter of the aluminum conductors (10, 10A).
