GORE® Shielded Twisted Pair Cables
Reliable signal transmission in high-density, lightweight construction
Engineered for the demanding environments of civil and military aerospace, GORE® Shielded Twisted Pair 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, and they maintain high-speed communication between avionics transmitters and receivers.
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 (Figure 1).
The excellent signal integrity of GORE® Shielded Twisted Pair Cables can enable utilization of smaller gauge cables in your system architecture. In addition, because of their electrical performance (Table 2) 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. GORE® Shielded Twisted Pair 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 flammability, smoke, and toxicity.
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.
