Winding wire SynWire W 220 Flat
- Enamelled flat copper wire, thermoresistant
- Insulated with polyamide-imide
- Class 220
SHTherm® 220 Flat is a highly thermoresistant enamelled copper wire of heat performance class R with superior thermal, chemical and mechanical resistance. It is used for special applications requiring the following criteria:
- very high permanent thermal resistance and short-time thermal overload
- very good resistance to aggressive mediums in liquid or gas form
SHTherm® 220 Flat is ideally suited for use in special safety-relevant and electrical life support equipment. Sophisticated process technology and process setting ensure easy mouldability, good elongation and constant insulation properties of these wires.
