UL3398 High-Temperature Hook-Up Wire – 150°C XLPE-Insulated Cable for Internal Wiring
UL3398 wire is a high-temperature electronic hook-up wire insulated with cross-linked polyethylene (XLPE) or flame-retardant XLPE (XLFRPE). Rated for 150°C and 300V, it is designed for use in internal wiring of electronic equipment, home appliances, industrial control panels, and other applications requiring superior heat and flame resistance.
Compliant with UL758, UL1581, and CSA standards, UL3398 wire offers excellent thermal stability, mechanical strength, and uniform insulation thickness for easy processing. It passes UL VW-1 and CSA FT1 flame tests, and meets RoHS environmental directives, making it suitable for harsh or confined environments.
Available in 10 AWG to 32 AWG, with solid or stranded, bare or tinned copper conductors, UL3398 is a reliable option for engineers seeking safety, flexibility, and space efficiency.
