MIL-W-25038/3 (Thermazone IIIK) wire-high-temperature, abrasion resistant
Thermazone IIIK wires are designed for critical circuit applications where wires must operate in extremely harsh environments, under vibration, and with direct flame exposure. Thermazone IIIG wires also meet or exceed the requirements of MIL-W-25083/3, but provides this performance at a lower cost through the use of an innovative insulation system.
