Fiberglass insulated aluminum wire

Description :
  The glass in Glass Fibre Conductor may be applied in woven tape form or as a continuous fibre. It has proved to be an efficient insulation providing coil winders with thermal stability, adequate electrical properties and good resistance to abrasion after varnishing. The glass is bonded with a varnish to improve dielectric strength and mechanical properties.
  Glass fibre-lapped conductors (bare or enameled) are very suitable for windings of electric motor stators, generators, special transfo rmers and high voltage motors. In general this insulation can be applied where high mechanical strength and high insulation properties are required. Most common application is in traction motors. It exhibits a very high degree of mechanical and thermal stability, either for class F and H insulation when impregnated with polyester, Polyesterimide or epoxy based impregnating varnishes. For higher thermal class, the Glass fibre-lapped conductors can be impregnated with silicone based resins of thermal class 200.
