PROCESSO DE FABRICACAO DE UM FIO ELETRICO ISOLADO,DO TIPO FIO ESMALTADO,POR EXTRUSAO

摘要

A method of extruding a thin sheath of plastic material about electric wire, utilizing a plastic material capable of being shaped by extrusion after having been heated in a screw extruder, this material exhibiting the technical characteristics required for enamel-type insulation after cooling, without necessitating subsequent treatment. An extrusion material containing at least one partially crystalline thermoplastic polycondensate wherein the crystallites have a melting-point above 170 DEG C. answers these requirements.
