Abstract

Official abstract text for this publication.

A multilayer insulated wire having a polyester-based resin layer formed of a polyester-based resin containing at least a trihydric or higher hydric alcohol constituent on a conductor, and a PEEK resin layer formed of polyether ether ketone or modified polyether ether ketone, directly or by interposing an intermediate layer, on the polyester-based resin layer; a coil formed by winding processing the insulated wire, and electronic/electrical equipment having the coil.

First claim

Opening claim text (preview).

1 . A multilayer insulated wire, comprising a polyester-based resin layer formed of a polyester-based resin containing at least a trihydric or higher hydric alcohol constituent on a conductor, and a PEEK resin layer formed of polyether ether ketone or modified polyether ether ketone, directly or by interposing an intermediate layer, on the polyester-based resin layer. 2 . The multilayer insulated wire according to claim 1 , wherein a content of the trihydric or higher hydric alcohol constituent is 30 to 90 mol % based on the total number of moles of the alcohol constituent that forms the polyester-based resin. 3 . The multilayer insulated wire according to claim 1 , wherein the trihydric or higher hydric alcohol constituent is a constituent derived from aliphatic alcohol. 4 . The multilayer insulated wire according to claim 1 , wherein the trihydric or higher hydric alcohol constituent is a constituent derived from at least one kind selected from the group consisting of trihydroxyethyl isocyanurate, glycerol and trimethylolpropane. 5 . The multilayer insulated wire according to claim 1 , wherein a total thickness of the polyester-based resin layer, the intermediate layer and the PEEK resin layer is 70 to 250 μm, and a proportion of the thickness of the PEEK resin layer to the total thickness is 20 to 70%. 6 . The multilayer insulated wire according claim 1 , wherein the conductor has a rectangular cross-section. 7 . A coil formed by winding processing the multilayer insulated wire according to claim 1 . 8 . Electronic/electrical equipment, having the coil according to claim 7 .
