Thermazone™ Wire & Cable


M25038

Carlisle Interconnect Technologies’ (CarlisleIT) Thermazone™ wires are designed for use in high temperature and severe environment applications such as engine wire, fire detection circuits, fly-by-wire systems and flight critical circuits. Three wire options are offered MIL-DTL-25038/1 (Thermazone I), MIL-DTL-25038/3 (Thermazone IIIK, IIIG) and BMS 13-55 (Boeing Material Spec).

The MIL-DTL-25038/1 (Thermazone I), MIL-DTL-25038/3 (Thermazone IIIK, IIIG) wires are ideal for critical circuit applications where wires must operate in extremely harsh environments, under vibration, and with direct flame exposure. Their heavy-duty, non-asbestos construction offers excellent mechanical performance and abrasion resistance. Thermazone IIIG meets or exceeds Thermazone IIIK’s performance due to the use of an innovative insulation which incorporates a PTFE coated fiberglass fluid barrier. The Thermazone IIIK is compatible with MIL-DTL-38999 connectors.

The BMS 13-55 Boeing Material Spec Firezone wire is intended for operation under short-term emergency conditions including exposure to flames with temperatures up to 1100°C and in areas where exposure to thermal changes and corrosive fluids are normal.

ESW Firezone Cables

A range of high temperature, fire proof and fire resistant single and multi-core cables, incorporating PTFE and Polyimide, specifically designed for use in fire zone areas of the aircraft engine.

BMS 13-55 Firezone Wire

BMS 13-55 is the Boeing specification for Firezone wire. These 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 Wire

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