AI Technical Summary

Technical Problem

Existing high-temperature resistant aviation cables are insufficient in terms of resistance to external electromagnetic interference, weight, and flexibility, making it difficult to meet the high requirements of the aerospace industry.

Method used

The cable uses multi-strand twisted plated copper wire as the conductor, combined with a three-layer wrapping insulation structure of low-density microporous tape and PTFE raw material tape, plus silver-plated copper tape armor and silver-plated copper wire braided shielding layer, with a polyimide film as the middle layer and a high-flexibility, high-strength, flame-retardant thermoplastic elastomer material as the outer sheath, forming a high-temperature resistant, flexible twisted pair communication cable.

Benefits of technology

It achieves low attenuation, high shielding, high flexibility, light weight, high temperature resistance, chemical corrosion resistance and radiation resistance, and is suitable for a wide temperature range of -60℃ to 150℃, meeting the long-term use requirements of aerospace systems under high temperature.
