<P>PROBLEM TO BE SOLVED: To provide an insulated wire having partial discharge resistance comparable to or higher than those of conventional insulated wires irrespective of a change in factors of an environment where electrical equipment is located. <P>SOLUTION: In an insulated wire according to the present invention, plural layers of insulation coatings are formed around an outer periphery of a conductor. The plural layers of insulation coatings include at least two layers including: a first insulation coating in which inorganic fine particles are dispersed; and a second insulation coating which is provided at the inside of the first insulation coating and has a relative dielectric constant lower than that of the first insulation coating. <P>COPYRIGHT: (C)2013,JPO&INPIT |
