MIL-W-25038 Wires

These wires are designed for critical circuit applications where wires must operate in extremely harsh environments, under vibration, and with direct flame exposure.

Key Features

• Firezone wires for aircraft engine applications are designed to operate continuously at 260°C
• Firezone applications are designed to operate for minimum of 15 minutes at up to 2000°F (1093°C), including in a direct flame
• Firezone qualification must pass BSS 7324 and M25038 Shake and Bake Test

Shake and Bake Test Description:

• Wire must withstand a flame temperature of 2,000° ± 50°F for 15 minutes
• After the flame has been stabilized, the wire is vibrated 30 times per second, with the rack having a maximum total excursion (overall movement) of approximately .06 inches (1.52mm)
• After 15 minutes, the lowest insulation resistance is measured
• No insulation can flake or fall off during the flame exposure
