摘要

The wire has a conductor and at least three insulating layers. The first and second layers, from the conductor, are (a) extrusion coated layers of an intimate mixt. of 100 pts. thermoplastic, straight-chain, polyester and 5-40 pts. wt. copolymer of ethylene with carboxylic acids or their metal salts in the side-chain. (b) an extrusion-coated layer of a thermoplastic, straight-chain, polyester prod. from an acid component and an alcohol component which is at least partly cyclohexane dimethanol, or (c) an extrusion-coated layer which is an intimate mixt. of 100 pts. wt. polyester made from cyclohexane dimethanol and up to 50 pts. wt. ethylene copolymer with carboxylic acids or their salts in the side chain, and the third layer is an extrusion-coated layer of a thermoplastic polyamide or an intimate polymer mixture consisting essentially of the polyamide. USE/ADVANTAGE - In electrical or electronic devices such as windings for transformers. Good windability, separability between the layers, solderability without change in the insulating props. and good reliability.
