UL 3321

UL 3321

UL 3321 wire has excellent mechanical and electrical properties. This wire is known for its unparalleled thermal stability, toughness, and abrasion resistance. It is compatible with all magnet wire and most varnishes. Its irradiated cross-linked insulation will not melt or flow at soldering temperatures. UL 3321 wire is often used in appliances, transformers, motors, ballasts, lighting, electrical heating, and cooking equipment. This wire also possesses outstanding resistance to abrasion, deformation, cut-through and chemical attack.
