Product Description
In glass-fibre insulated conductor the insulation is formed by double-braiding thin glass-fibre yarn around the conductor and then saturating it with a heat-cured resin. The resulting shell is mechanically hard and abrasion-resistant; it protects the conductor against sharp edges and high pulling forces during winding.
Because glass fibre is an inorganic material it does not decompose at high temperature; the main factor setting the thermal class is the binder resin used. Classes 180 (H) and 200 (N) are obtained with silicone or modified-polyester based binders.
The porous structure of the insulation is well suited to the vacuum-pressure impregnation (VPI) process: the varnish penetrates the braid and, after curing, the winding becomes a single piece. Conductor dimensions are produced to the dimension and tolerance approach of the IEC 60317 series.
Applications
Large electric motors, generator windings, electromagnets, arc-furnace transformers, industrial reactors.
