Class 200 Glass Fiber Covered Silicone Treated Film-Insulated Round Copper Magnet Wire

Class 200 Glass Fiber Covered Silicone Treated Film-Insulated Round Copper Magnet Wire combines several insulation to enhance the wire’s performance under high temperatures and demanding electrical conditions.

The glass fiber covering shall be wrapped firmly, closely, evenly, and continuously around the wire. The glass fiber covering shall be treated with a modified silicone insulating varnish or silicone compound to provide a tough outer finish. If a tracer is used, one or more ends of glass yarn in the outer layer shall be black or green, and the dye or pigment used for this purpose shall be sufficiently stable so as to retain its color identity after the silicone treatment and subsequent baking.
