Title:
絶縁電線ならびにそれを用いた電気・電子機器、モーターおよびトランス
Document Type and Number:
Japanese Patent JP6452444
Kind Code:
B2
Abstract:
An insulated wire having a rectangular shaped cross-section, containing: a conductor having a rectangular shaped cross-section; and an insulating layer coated on the conductor, in which the insulating layer has a foamed layer composed of a thermosetting resin containing bubbles, the cross-section of the insulating layer has a shape composed of a flat portion and a corner portion, and the insulating layer satisfies the relationship represented by the following formula: µ 1 < 3 and T 2 / µ 2 > T 1 / µ 1 wherein T 1 [µm] represents a thickness of the flat portion; µ 1 represents a relative dielectric constant of the flat portion; T 2 [µm] represents a thickness of the corner portion; and µ 2 represents a relative dielectric constant of the corner portion, and an electric/electronic equipment, a motor, or a transformer, using the insulated wire.
