As the trend towards electrification and higher DC voltage increases in aircraft, wire insulation becomes critical to ensure system reliability, functionality and safety. But, higher voltages put more electrical stress on wiring, which means more risks from physical damage. You can increase the amount of insulation to add more durability, but increasing wire size and weight also add aircraft weight.

The GWN3000 Series of GORE High Performance Aerospace Wires offers the best combination of superior mechanical strength and outstanding electrical reliability without increasing wire bundle size or weight. They meet higher mechanical and electrical durability levels for wire bundles operating in severe conditions.

The key is our proprietary fluoropolymer that has a higher PDIV/PDEV with a proven higher voltage breakdown and endurance than other materials. This unique insulation can easily resist extreme operating temperatures, harsh chemicals and humidity without degrading. Unlike other materials, our insulation is also proven to reduce chafing, abrasion and cut-through failures.

Ultimately, we’ve developed an optimal solution that OEMs and program managers want and need for future aircraft electrification. Our GWN3000 Series provides aircraft systems with a higher level of mechanical and electrical performance over time.

With GORE High Performance Aerospace Wires installed in your aircraft, you can ensure operational readiness and EWIS reliability, increase aircraft availability, improve safety and reduce your total costs.

Review the table below to compare GORE High Performance Aerospace Wires, GWN3000 Series against other insulation materials.

Note that current wiring solutions either contain polyimide or exhibit limitations in physical and electrical properties. The yellow squares indicate good overall abrasion test results. But, the underlying polyimide is quickly exposed, which risks degradation, arc tracking, and more. Any Improvements to these materials are likely to involve an increase in wire size and weight.
