In the aerospace industry, every gram of weight and every millisecond of performance matter.
Aerospace cables are specialized electrical wires designed to deliver reliable power, control, and data transmission in some of the most extreme environments known to man — from the vacuum of space to the intense heat of jet propulsion systems.
Aerospace cable
Engineered for lightweight durability, high temperature resistance, and electromagnetic shielding, aerospace cables are a critical component in aircraft, spacecraft, satellites, and defense systems.
What Is an Aerospace Cable?
An aerospace cable (also known as aircraft wire or aviation cable) is a high-performance electrical cable designed for aerospace-grade reliability under severe conditions such as vibration, radiation, temperature extremes, and exposure to fuels or hydraulic fluids.
These cables must comply with stringent standards such as AS9100, MIL-Spec (MIL-W-22759, MIL-DTL-27500), and SAE AS4373 to ensure safe and continuous operation in flight-critical systems.
Key Features and Advantages
✈️ Lightweight Design – Uses lightweight conductor alloys and thin-wall insulation to minimize aircraft mass.
🔥 High Temperature Resistance – Withstands continuous operation up to +260°C (500°F) using advanced insulation materials like PTFE, PFA, FEP, and ETFE.
🧲 EMI Shielding – Protects signal integrity from electromagnetic interference with silver-plated copper braid shields.
⚙️ Chemical and Fluid Resistance – Resists aviation fuels, hydraulic oils, lubricants, and cleaning agents.
🚀 Mechanical Strength – Designed to endure constant vibration, flexing, and mechanical stress during flight.
🌌 Radiation and UV Resistance – Ensures reliable performance in outer space and high-altitude conditions.
