UL 3321

UL 3321 combines flexible annealed tinned copper conductors with chemically cross-linked polyethylene (XLPE) insulation, engineered for superior thermal and mechanical durability. This professional-grade 600V-rated wire excels in temperatures up to 150°C while providing exceptional resistance to abrasion, deformation, cut-through, and chemical exposure. Certified to UL 3321/UL 3505 and CL 1503/AWM standards with RoHS compliance, this specialized wire maintains structural integrity at soldering temperatures without melting or flowing. The advanced XLPE insulation ensures maximum compatibility with magnet wire and varnishes, making it ideal for transformers, motors, ballasts, and electrical heating equipment. Perfect for applications requiring outstanding thermal stability and mechanical toughness, this versatile wire delivers reliable performance in appliances, lighting systems, and cooking equipment where consistent electrical properties are essential.
