Double Fiber Glass Insulated Copper Conductors (DFGC) are used for winding coils of Electric Motor Stators, Generators, Special Transformers and High Voltage Motors where high mechanical strength & high insulation properties are required. Fibre Glass Covered Conductor is bonded with a Varnish for dielectric strength to improve mechanical properties.
