Ceramic pre-insulation electric wire and self welding property ceramic pre-insulation electric wire, constituent for coat, coil and voice coil null for speaker

摘要

PROBLEM TO BE SOLVED: To provide a self-welding ceramic insulated cable capable of maintaining coil characteristics under high temperatures.;SOLUTION: A coating composition containing zirconium compound and silicon compound is coated and baked on a conductor 1, and a ceramic insulated coating 2 is formed, and a fusible coating in which a polyamide series resin or polyimide series resin dissolved in organic solvent(s) is coated and baked, and thereby a fused coating 3 is formed. This can be used appropriately for winding wire of a voice coil or the like for a high-output loudspeaker.;COPYRIGHT: (C)2002,JPO
