UL3302 is a UL‑recognized high‑temperature halogen‑free electronic hook‑up wire. It adopts ultra‑fine stranded tinned copper conductor and cross‑linked polyethylene (XLPE) halogen‑free insulation material.
This wire has outstanding heat‑resistance performance, low‑smoke and halogen‑free characteristics when burned. No toxic halogen gas releases under fire condition, suitable for equipment requiring high‑level environmental safety. Ultra‑fine conductor structure delivers superior flexibility for narrow‑space internal wiring. It can be processed into various finished wire harnesses by stripping, tin‑dipping and connector crimping. Mainly used in household appliances, smart devices, battery packs, medical electronics and industrial control modules.
