UL 5128

UL 5128

UL 5128 wire is manufactured from a reinforced mica tape insulation and a braided fiberglass jacket for enhanced abrasion resistance. UL 5128 wire meets all UL requirements for appliance lead wire and is also available with CSA certification. This wire may be used for applications in a high-temperature appliance, igniter cables for furnaces, thermocouple cables, electrical heaters, and other high-temperature cable applications. They are also used in military shipboard cables where low-smoke halogen-free cables are required.
