Winding wire
SHTherm® 210 Alu
- Enamelled al.wire
- Insulated with theic-mod. polyesterimide and amid-imid topcoat
- Class 200
Attributes
SHTherm® 210 AL is a highly thermo-resistant enamelled aluminium wire of heat performance class N with a wide range of good and very good quality features. As it is a dual-coat wire its insulation film consists of two different coatings on top of one another. These ensure: a very good permanent thermal and overload resistance, excellent esistance to chemical attacks e.g. by alkalines, washing and cleaning agents, impregnating varnishes and resins, sealing compounds, thinners, solvents and refrigerants as well as their vapours, an excellent mechanical abrasion resistance.
On demand the system can be offered with an additional layer of selflubricating enamel thus giving enhanced properties for winding operations.
Application
Control gears, drives for household equipment, electric motor drives, pump drives, refrigerators, transformers
