Bell Helicopter Textron M22759/41-22-9 Electrical Wire 300′

The M22759/41-22-9 is a SAE AS22759/41 compliant electrical wire designed for aerospace and helicopter wiring systems operating in high-temperature, high-stress environments. It features stranded nickel-plated copper conductors with cross-linked modified ETFE dual-wall insulation, delivering 600 V rating at 200°C continuous operation. The dual-layer construction provides superior cut-through and abrasion resistance while enabling quick visual identification of damage through distinct color contrasts. This 22 AWG wire maintains tensile strength ≥34.5 MPa and elongation ≥100%, with high residual properties after thermal aging (≥85% tensile strength and ≥75% elongation following 180°C exposure for 168 hours). Dielectric withstand voltage reaches 2.5 kV AC at 60 seconds without breakdown. Finished wire diameter (insulation O.D.) ranges 0.048–0.052 inches with approximate weight of 3.20 pounds per 1000 feet. The wire resists flame, chemical attack, radiation, and soldering iron contact, making it suitable for critical airframe, avionics, and military defense applications where reliability is non-negotiable.
