GORE^® High Performance Aerospace Wires for Defense Aircraft

When it comes to aircraft electrification, aircraft wire insulation must be durable enough to ensure reliable EWIS (electrical wire interconnection systems). But electrification requires higher aircraft voltage, which stresses wiring more and causes potential physical damage. Typical insulation materials are often limited in durability and degrade over time when exposed to harsh airborne conditions. You can add extra aerospace wiring insulation for more durability, but it increases wire bundle size and weight, plus adds unwanted aircraft weight.

Gore offers a single optimal solution that OEMs (original equipment manufacturers) and program managers want and need for future military aircraft electrification.

GORE High Performance Aerospace Wires offer greater mechanical strength and exceptional electrical reliability over time without adding to wire bundle size and weight. They meet higher durability levels for aircraft electrical wire bundles operating in severe airborne conditions. We thoroughly test our wires to meet the most current aircraft wiring standards, like ASTM D3032 and SAE AS4373™.

Our wire insulation is proven to have a higher PDIV/PDEV while displaying higher voltage breakdown and endurance than alternative aerospace wire and cable materials. This unique aircraft wire insulation offers other proven advantages over alternative materials, like resistance to extreme operating temperatures, humidity and harsh chemicals without degrading. And our insulation is proven to resist chafing, abrasion and cut-through failures.

Review the table below to compare the insulation material in GORE High Performance Aerospace Wires against common insulation materials for aircraft wires and cables.

Keep in mind that current aircraft electrical wiring solutions either contain polyimide or show limitations in physical and electrical properties. The yellow squares indicate good overall results from our abrasion testing. But, the underlying polyimide is quickly exposed, risking degradation, arc tracking and more. Any improvements to these materials in commonly used aircraft electrical wire types to add durability will likely add size and weight.

Unlike common insulation materials, GORE High Performance Aerospace Wires offer unique features that provide long-term stability against challenging environmental factors and aircraft conditions, including:

• low-permittivity, higher PDIV/PDEV material
• temperature-resistant, chemically inert, non-flammable material
• abrasion- and cut-through resistant material
• hydrophobic, non-hydrolyzing material

For system architects and engineers, our aircraft power wires deliver numerous benefits that meet military aircraft electrification needs and requirements, like:

• proven strength against chafing, abrasion and cut-through over wide temps
• resist chemicals or fire for increased aircraft safety and improved system performance
• no degradation over time from hydrophobic, non-hydrolyzing material
• improved electrical durability and less voltage breakdown over time in demanding MEA applications
• greater EWIS reliability, increased aircraft availability and reduced costs
• increased future-proofing with wires that can withstand higher voltage requirements

Meet all your electrical wire system needs with our single optimal solution that ensures EWIS reliability over time, increases aircraft availability, improves safety and reduces total costs.
