Winding wire SHTherm® 210 Flat Alu
- Enamelled flat aluminium wire, thermoresistant
- insulated with THEIC mod. polyesterimide with polyamide-imide topcoat
- Class 200
SHTherm® 210 Flat Alu is a highly thermoresistant rectangular enamelled aluminium wire of heat performance class N with a wide range of good to very good quality features. Its insulation film consists of 2 different coatings on top of one another. These ensure a very good permanent thermal and overload resistance, excellent resistance against mechanical stress, as well as an excellent resistance to chemical attacks of commercial washing and cleaning agents, impregnating varnishes and resins, sealing compounds, thinners, solvents and refrigerants, oils as well as their vapours. This range of excellent features make SHTherm® 210 Flat Alu an all-round wire meeting the requirements of all applications with above average requirements to processing and operational features or operational safety in electrical systems.
