Abstract

An electric wire includes: a core wire made by stranding a plurality of element wires each of which is made of aluminum or aluminum alloy, and has a circular sectional shape; and an insulating cover covering the core wire. The number of the element wires is equal to or more than 19 and equal to or less than 37. A diameter of the element wire is equal to or more than 0.15 mm, and equal to or less than 0.30 mm. A total cross-sectional area of the stranded element wires is equal to or more than 0.34 mm² and equal to or less than 2.61 mm². A strand pitch of the stranded element wires is equal to or more than 3 times and equal to or less than 40 times of a center diameter ‘B’ of the core wire.

Claims

1. An electric wire comprising:

a core wire made by stranding a plurality of element wires, each of said element wire being made of aluminum or aluminum alloy, and each of said element wire having a circular sectional shape; and

an insulating cover covering the core wire,

wherein the number of the element wires is equal to or more than 19 and equal to or less than 37,

wherein a diameter of the element wire is equal to or more than 0.15 mm, and equal to or less than 0.30 mm,

wherein a total cross-sectional area of the stranded element wires is equal to or more than 0.34 mm² and equal to or less than 2.61 mm², and

wherein a strand pitch of the stranded element wires is equal to or more than 3 times and equal to or less than 40 times of a center diameter of the core wire.

2. An electric wire comprising:

a core wire made by stranding a plurality of element wires, each of said element wire being made of aluminum or aluminum alloy, and each of said element wire having a circular sectional shape; and

an insulating cover covering the core wire,

wherein the number of the element wires is equal to or more than 37 and equal to or less than 84,

wherein a diameter of the element wire is equal to or more than 0.15 mm, and equal to or less than 0.315 mm,

wherein a total cross-sectional area of the stranded element wires is equal to or more than 0.65 mm² and equal to or less than 6.54 mm², and

wherein a strand pitch of the stranded element wires is equal to or more than 3 times and equal to or less than 40 times of a center diameter of the core wire.
