1. An aluminum electrical wire, comprising:
- a conductor comprising a plurality of aluminum-based core wires; and
an insulating resin covering directly covering the conductor such that the insulating resin covering is in contact with the plurality of aluminum-based core wires and has a thickness deviation of not less than 70%,wherein the plurality of aluminum-based core wires contains 99 mass % of aluminum, and the conductor is constructed by concentrically twisting 19 or 37 of the aluminum-based core wires at a same pitch in a non-compressed state such that the aluminum electrical wire has a current capacity that is substantially same as a current capacity of a copper electrical wire having a diameter that is substantially same as a diameter of the aluminum electrical wire.

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.

18. A method for manufacturing an aluminum electrical wire, comprising:
-
constructing a conductor by twisting a plurality of aluminum-based core wires; and directly covering the conductor with an insulating resin covering such that the insulating resin covering is in contact with the plurality of aluminum-based core wires and has a thickness deviation of not less than 70%, wherein the plurality of aluminum-based core wires contains 99 mass % of aluminum, and the conductor is constructed by concentrically twisting 19 or 37 of the aluminum-based core wires at a same pitch in a non-compressed state such that the aluminum electrical wire has a current capacity that is substantially same as a current capacity of a copper electrical wire having a diameter that is substantially same as a diameter of the aluminum electrical wire. - View Dependent Claims (19, 20)
