Definitions
- the present invention relates to an improved method for producing insulated winding wires by extrusion of thermoplastics.
- Enamel-insulated winding wires so-called “enamelled wires” are precisely characterized in the German standard DIN 46435 from April 1977. They are used on a large scale in electrical engineering, transformer construction and electronics.
- the supply metal preferably copper or aluminum, is insulated with a thin, but mechanically and thermally extremely resistant synthetic resin lacquer layer.
- Such enamelled wires are produced on wire enamelling machines by repeatedly applying an enamelled wire enamel to the metal wire.
- wire enamel dispersions and aqueous solutions of wire enamel resins as well as resin melts are already used for wire enamelling.
- thermoplastics for thick-walled sheathing of electrical conductor bundles and for the production of conductor wires has long been known from the cable industry.
- DE-A-26 38 763 describes a process for the production of enamel-insulated winding wires by extrusion of partially crystalline thermoplastic polycondensates with crystallite melting points above 170 ° C., preferably above 250 ° C., in which thin insulating layers, as required by DIN 46435 will be preserved.
- polymers with chain sulfur atoms e.g. Called polyphenylene sulfide.
- the examples describe the extrusion conditions for polyethylene terephthalate, 6,6-polyamide and polyphenylene sulfide and the properties of the winding wires obtained therewith.
- the invention thus relates to the use of aromatic polyether ketones with recurring units of the formula where Ar is aromatic radicals, which may be the same or different, in particular benzene, naphthalene or diphenyl radicals, where n is an integer from 50 to 200, for the production of insulated copper winding wires in the extrusion process, the layer thickness of the insulation meets the requirements of the German standard DIN 46435 (April 1977).
- thermoplastics In comparison to the values for the other thermoplastics, the thermal shock value of the winding wires insulated with polyether ketone coating is surprisingly greatly improved.
- Coating material Semi-crystalline aromatic polyetherketone of the summary formula Crystallite melting point 335 ° C.
