Winding wire SHTherm® 220 Glide
- Enamelled round copper wire, thermoresistant and self lubricating
- Insulated with polyamide-imide
- Class 220
SHTherm® 220 Glide 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 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.
The final layer of varnish serves the purpose of providing a superior gliding surface, giving the wire excellent windability features at higher speeds, and enabling a higher filling factor plus reduced soiling of the winding machines. The reduced coefficient of friction helps to avoid damage to the wire during winding and thus maintains the insualtion properties of the wire.
Application
