Industry Applications

Aircraft Engine Fire Zones

Provides reliable signal routing near engine nacelles and exhaust manifolds, ensuring critical sensors transmit vital telemetry during high-heat or localized fire events.

Emergency Power Systems

Acts as the electrical backbone for auxiliary power units (APUs) and emergency backup systems, maintaining line continuity when primary infrastructure fails.

Fly-By-Wire Flight Controls

Safeguards flight-critical actuation circuits, guaranteeing that pilot commands reach control surfaces even under severe thermal degradation or combat damage.

Fuel System Monitoring

Connects deep-tank fuel sensors and management valves, offering high resistance to continuous chemical exposure, fuel vapor saturation, and vibration.

Military UAV Deployments

Delivers lightweight, high-reliability wiring harnesses for unmanned defense platforms operating under extreme environmental profiles and rapid thermal cycling.

Space Launch Vehicles

Powers thrust vector control systems and staging telemetry cables that must withstand localized friction-induced heat during atmospheric ascent.

Having Doubts? Our FAQ

Can we customize the AWG sizing and conductor stranding for our specific aerospace drawing?

Yes. Frigate manufactures custom MIL-DTL-25038 configurations tailored to your specific envelope limits, including varying strand counts and nickel-clad conductor thicknesses to match your exact flexibility and resistance targets.

How does Frigate validate conformance to the 2000°F flame test requirement?

Every production lot undergoes rigorous quality conformance testing. We expose the wire to a continuous 1093°C (2000°F) flame under rated voltage and vibration to verify that no electrical breakdown occurs during the specified survival window.

What documentation and certifications are provided with an enterprise shipment?

All shipments are accompanied by a full First Article Inspection (FAI) report, a formal Certificate of Conformance (CoC), material test reports detailing chemical analysis of the insulation, and electrical trace data for full military traceability.

How does this wire perform under continuous exposure to hydraulic fluids?

The outer protective glass jacket and high-fluoropolymer barrier are specifically engineered to resist chemical degradation. They will not swell, soften, or lose dielectric strength, JP-8, or aggressive aviation cleaning solvents.

Can you accommodate expedited lead times for sudden line-down scenarios?

We maintain an agile manufacturing pipeline for critical aerospace defense projects. If you are facing an AOG (Aircraft on Ground) or tight defense deadline, our engineering team can review raw material availability to compress standard scheduling.
