Electric Winding Body with Optimised Performance Characteristics and Improved Protection Against Overheating

An electrical winding form comprising electrically conductive windings around a core, wherein the windings have cavities between them that are filled in a form-fitting manner by a thermoplastic material, the thermoplastic material comprising a mixture of

• a) a network-forming thermoplastic elastomer which, in the range of 120-150° C., has flowability and a melt flow index of at least 15 g/10 min, at 190° C./2.16 kg measured per ISO 1133-1 and
• b) a phase change material having a phase change temperature between 40° C. and 140° C., where the phase change material is present in the thermoplastic material in a proportion of 50% to 85% by weight.
