Conductor : aluminum
Fiber Glass Covered Aluminum Wire uses an aluminum conductor and achieves multi-layer insulation through successive coatings of insulating varnish and tightly wrapped glass fibers.
Glass fiber covered aluminum wire structure 1
Inner layer: Rectangular or round aluminum wire.
Middle layer: Coated with 0.2–0.5 mm of high-temperature resistant insulating varnish (polyesterimide or polyimide).
Glass fiber layer: Single or double-layer mesh-braided glass fiber wrapping.
Outer layer: A secondary high-temperature varnish coating that cures into a seamless insulation layer.
