(EN) SELF-BONDING INSULATED ELECTRIC WIRE AND ELECTRIC WIRE FOR COIL
要約
(EN)
An object of the present invention is to provide a self-bonding insulated electric wire with which windings of the electric wire can be easily fixed to each other and generation of dust is suppressed. A self-bonding insulated electric wire according to one embodiment of the present invention includes a linear metal conductor (1), an insulating layer (2) stacked on an outer circumference side of the metal conductor (1), an expansion layer (3) that is stacked on an outer circumference side of the insulating layer (2) and is thermally expandable, and a thermal bonding layer (4) stacked on an outer circumference side of the expansion layer (3). The expansion layer (3) may include a matrix (5) containing a synthetic resin as a main component, and a chemical foaming agent (6) or thermally expandable microcapsules dispersed in the matrix (5). The average thickness expansion factor of the expansion layer (3) after heating is preferably 1.1 or more and 5 or less. The porosity of the expansion layer (3) after heating is preferably 10% or more and 80% or less. The average thickness of the thermal bonding layer (4) is preferably 5 �m or more and 200 �m or less.
