What is Polyester Glass Fiber?
Polyester glass fiber cloth is a common textile covering, wrapped with conductor wires in a heat-treated combination. This method can be made of single or double glass yarn. Polyester, epoxy or silicon varnish is available. Usually used for standard temperature applications with or without appropriate varnish. It can be applied to bare conductors, various types of coated conductors or other insulating layers. This allows the yarn to wrap around the wire, creating a protective layer over the wire. The yarn is then cured at high temperatures and fused with the wire to become a protective insulating barrier. Once complete, the insulation allows the wire to function properly at temperatures between -196C and 300C when a glass fiber cloth is used.
