ELECTRICAL INSULATION Since its establishment in 1949, Polygon Company has stood as one ofthe worldْs premiere leaders in the development of advanced compos-ite materials for many electrical insulative applications. Polygons pro- duction capabilities are among the widest in the world and range from the pultrusion process to filament winding, braiding and circ-winding.In addition, Polygon is known as the worldҒs leading fabricator of com-posite materials. > The Polygon Tube is the insulation sleeve that provides armatures of electric motors a secondary layer of insula-tion. This secondary...

ELECTRICAL INSULATION The anisotropic properties composite materials are often misunderstood. Therefore, it is helpful to reviewsome of Polygon Tube'sٙ basic material features as they relate to armature insulation. > THE COMPOSITE TUBE CONSISTS PRIMARILY OF TWO DIELECTRIC MATERIALS: REINFORCING MATERIAL: Consisting of continuous fiber bundles of electrical grade "E-Glass" woven togetherat a specific helix angle with respect to the tube axis and thermoset epoxy resin, property retention (bothin-dielectric and structural) electrical temps. EPOXY: That has a Tg of approximately 120C [266F] or...
