The 331249-000 is a high-performance SPEC 55 wire insulated with a modified radiation cross-linked ETFE polymer. It features a continuous operating temperature range of -65°C to 200°C, combining the easy handling of a flexible wire with excellent scrape abrasion and cut-through resistance. The insulation is highly resistant to chemicals, solvents, UV degradation, and moisture. Due to its small size, light weight, and resistance to electrical arc tracking, it is an ideal choice for commercial and defense aerospace platforms, including airframe harnesses and internal equipment wiring.
