Winding wire SHTherm® 210 Flat
- Enamelled flat copper wire, thermoresistant
- Polyesterimide overcoated with
- polyamide-imide enamel
- Class 200/220
SHTherm® 210 Flat is a highly thermoresistant rectangular enamelled copper wire of heat performance class N with a wide range of excellent 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 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.
The consistent further developments carried out by our R&D team allow this excellent “all-round” wire to be optimised to take into account specific customer requirements (e.g. improved adhesion after ageing, workability, electrical characteristics).
