UL 3321 wire is a type of hook-up wire known for its high-temperature resistance and durability, making it suitable for various applications, particularly in appliances and electrical equipment. It features cross-linked polyethylene (XLPE) insulation, which provides excellent thermal stability and resistance to abrasion, deformation, and chemical attack.
High-Temperature Resistance:UL 3321 wire is designed to operate in high-temperature environments, withstanding temperatures up to 150°C.
Cross-linked Polyethylene Insulation (XLPE):The XLPE insulation provides excellent thermal stability and resistance to melting or flow at soldering temperatures.
Abrasion and Chemical Resistance:It is highly resistant to abrasion, deformation, cut-through, and chemical attack, enhancing its durability and longevity.Voltage Rating:UL 3321 wire is typically rated for 600 VAC and 750 VDC applications.
Applications:It is commonly used in appliances, transformers, motors, ballasts, lighting, electrical heating, and cooking equipment.
RoHS Compliant:UL 3321 wire is RoHS compliant, meaning it meets environmental standards regarding hazardous substances.
Construction:It typically consists of stranded, annealed, and optionally tinned copper conductor with XLPE insulation.
Color Options:It is available in various colors as per customer specifications.
