Product Details

These wires are designed for critical circuit applications that require operation in extremely harsh environments, under vibration, and with direct flame exposure.

  • Designed to operate continuously at 260 °C
  • Designed to operate for a minimum of 15 minutes at up to 2000 °F (1093 °C), including in a direct flame
  • Firezone qualification must pass BSS 7324 & M25038 Shake & Bake Test

Construction

Performance

  • 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 (1.52 mm)
  • After 15 minutes, the lowest insulation resistance is measured
  • No insulation can flake or fall off during the flame exposure
