155 CLASS SELF BONDING ULTRA FINE MAGNET WIRE VARNISH ENAMELED COPPER WIRE
Film or coatings will conform to the latest revisions of the applicable standards of ANSI, ASTM, or NEMA. Various resins are referred in Section 2 as the basecoat and overcoat. The resins specified may be modified. A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. But it will retain the essential chemical identity of the original resin and the coated conductor will meet all specified test requirements of the appropriate NEMA standard (for UL approved items
