Claims

[Scope of utility model registration request]

(1) In a transformer in which one phase of the three-phase winding is shared as a three-phase winding and a single-phase winding, the winding of the phase winding that is shared as the three-phase winding and the single-phase winding. A transformer characterized by being wound with a material that has higher conductivity than other two-phase windings.

(2) At least one of the primary winding or the secondary winding of the phase winding that is shared by the three-phase winding and the single-phase winding is wound with a winding material having high conductivity. A transformer according to claim 1 of the utility model registration claim.

(3) The transformer according to claim 1, wherein the winding material with high conductivity is a copper conductor, and the other winding materials are aluminum conductors.
