Mysun Wire and Cable’s UL 3239 wire is a hookup wire manufactured with fully annealed tinned copper, flexible stranding and insulation resistant to abrasion, deformation, cut-through and chemical attack. UL 3239 wire’s tough insulation resists shrink-back and melting, even when in direct contact with a soldering iron. UL 3239 wire’s insulation provides the same excellent flame-retardant properties as the best PVC insulations. UL 3239 wire does not melt or shrink back at termination, making it an outstanding high voltage wire specially designed for consumer electronics, appliances, test equipment, and instrumentation. UL 3239 wire is also rated 150°C and categorized as a High Voltage Lead Wire (HVSR). It is recognized by UL as style 3239 standards.
