Winding wire SHTherm® 200
- Enamelled round cu.wire, thermo-resistant
- Insulated with theic-mod. polyesterimide
- Class 180
SHTherm® 200 is a highly thermo-resistant enamelled copper wire of heat performance class H. Its single coat insulation offers very good resistance to thermal overloads, thanks to its high thermoplastic flow and heat shock temperature. It also provides good resistance to commercial impregnating agents, impregnating resins, extrusion-coating agents, sealing resins, solvents and detergents. Furthermore the insulating enamel film distinguishes itself through high film elasticity and abrasion resistance. Sophisticated process technology and process setting ensure easy mouldability, very good elongation properties and low coefficients of friction, as well as good and constant dielectric insulation properties of these wires. In particular, resistance to dichlorodifluormethane (Freon) is to be emphasized. Thanks to the described wide range of excellent properties SH Therm® 200 is ideally suited for all standard applications in heat performance classes F and H, when sophisticated winding and draw-in technologies are used, as well as for use in refrigeration machines filled with Freon. SHTherm® 200 can be welded and mechanically connected but is not solderable.
