Winding wire SHTherm® 220

  • Enamelled round cu.wire, thermo-resistant,
  • Insulated with polyamide-Imide
  • Class 220

"SHTherm® 220" is a highly thermo-resistant enamelled copper wire with 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" 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.
