Regular Square Insulating Cable, Application of Such Regular Square Insulating Cable and Method for Manufacturing Such Regular Square Insulating Cable

Abstract

A first insulating layer 1 is formed by electrodeposition coating on the surface of an outer circumference of a linear conductor m wherein the cross sectional shape thereof is substantially square, and further thereon, a second insulating layer 2 is formed by dipping. In the formation of the first insulating layer 1, swelling occurs in the first insulating layer at a corner portion of conductor m due to the electrodeposition characteristics of electrodeposition coating. The relative concavo-convex occurs on the surface of the layer 1 by the swelling. The concavo-convex is planarized by the second insulating layer formed in accordance with film-forming characteristics of the dipping, whereby an insulated square wire superior in voltage resistance and conductor space factor is obtained.
