Class 180 Polyester Glass Fiber Covered High-Temperature Round Copper Magnet Wire

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%. If underlying film insulation is used, it shall have at least a class 155 rating and comply with the applicable specification of Polyester Glass Fiber Covered Round 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 shall be treated with a high-temperature non-silicone organic insulating varnish.
