Insulating Material

The fiber covering shall consist of a combination of polyester and glass fibers.

The glass fibers shall be electrical-grade continuous-filament glass yarn.

The polyester fiber shall be a high-grade yarn resulting from the linear polymerization of ethylene glycol and terephthalic acid.

The maximum content by weight of polyester fiber in the yarn shall not exceed 50%. The underlying film insulation shall have at least a class 180 rating and comply with the applicable specification of Polyester Glass Fiber Film-Insulated Rectangular Copper Magnet Wire. The polyester glass fiber covering shall be wrapped firmly, closely, evenly, and continuously around the wire. The polyester glass fiber covering shall be fused and treated with a modified silicone insulating varnish. 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.
