MIL-DTL-M22759/30 wires have extruded PTFE insulation with a polyimide hard coat for increased cut-through and abrasion resistance, and a high-strength copper alloy conductor for greater break strength. These wires are designed for aerospace and other applications requiring excellent thermal stability, tight dimensional tolerances, and high reliability. These wires are especially well-suited in applications where smoke emission, overload stability, and flammability are major concerns.
