GORE® Shielded Twisted Pair Cables
Reliable signal transmission in high-density, lightweight constructions
Engineered for demanding aerospace environments, GORE®
Aerospace Cables are constructed with uniquely engineered
fluoropolymers that deliver high-speed data transmission
in a lightweight package. These cables meet the performance
requirements of ANSI/NEMA WC 27500 Standard for Aerospace
and Industrial Electrical Cable, Type 24. GORE® Aerospace Cables maintain high-speed communication on avionics networks.
Well-suited for aerospace harness applications, GORE® Shielded Twisted Pair Cables are highly flexible and easy to route in confined spaces. These cables provide excellent signal integrity while reducing weight by as much as 35% when compared to standard cables. In addition, the combination of materials in this construction supports a wide temperature range to meet the most demanding aerospace environments. GORE® Shielded Twisted Pair Cables are available in six standard sizes ranging from 20 AWG to 30 AWG.
- Avionics electronics
- Digital video systems
- Cabin management systems
- Ethernet networks
- Serial buses
Comparison of Round Cable Diameters
Weight Savings with Gore Cable TechnologyGORE® Shielded Twisted Pair Cables can significantly reduce weight while maintaining reliable signal integrity. Jacket weight is reduced by as much as 37 percent when compared to ethylene tetrafluoroethylene (ETFE) materials and 50 percent when compared to fluorinated ethylene propylene (FEP). These lighter-weight materials also result in smaller cable diameters, which ultimately translate to significantly smaller, lighter, and higher-density cable bundles.
The excellent signal integrity of GORE® Shielded Twisted Pair Cables can enable utilization of smaller gauge cables in your system architecture. Because of their electrical performance and long transmission distances, these cables can reduce the need for additional signal amplification — further decreasing weight and power requirements.
Reliable Flight PerformanceGORE® Shielded Twisted Pair Cables deliver dependable signal integrity for high-speed data transmission in demanding aerospace environments. These cables maintain reliable performance in extreme temperatures ranging from -55°C to 200°C, including rapid changes in temperatures encountered during take-off and landing. These cables also meet FAA Requirements for smoke and flammability.
Easier InstallationGORE® Shielded Twisted Pair Cables facilitate easier installation. The small cable diameter increases flexibility with a tight bend radius, which makes initial routing easier.
