MIL-W-25038/3
Application and Description:
These PTFE insulated single-core MIL-W-25038/3 cables are used in such aerospace applications as engine compartments, fire detection circuits, flight-critical circuits, and fly-by-wire systems. MIL-W-25038/3 (Thermazone IIIK) wires are designed for critical circuit applications where wires must operate in extremely harsh environments, under vibration, and with direct flame exposure. MIL-W-25038/3(Thermazone IIIG) wires also meet or exceed the requirements of MIL-W-25083/3, but provide this performance at a lower cost through the use of an innovative insulation system.
Construction:
Conductor: 12-18 AWG: Stranded 27% Nickel coated copper conductor
20-22 AWG: Stranded 27% Nickel coated high-strength copper alloy conductor
Insulation:
Thermazone IIIK:
Outer: PTFE/polyimide tape fluid barrier.
