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
FEATURES AND BENEFITS
Uniformity and degree of insulation
Good electrical characteristics such as dielectric strength and
insulation resistance
Resistant coating to mechanical stress induced by bending,
stretching, and friction
Heat-resistance
Resistant to solvents, chemicals and varnishes
