ENSURE EWIS RELIABILITY OVER TIME WITH DURABLE, LIGHT WIRE BUNDLES.
Current electrical wire interconnection systems (EWIS) may not fulfill next-gen aviation requirements or address future aircraft electrification to help reduce air transport’s toll on the environment. Voltages are increasing to avoid weight gain, but they also put more electrical stress and risk damage to wiring. Thankfully, W. L. Gore & Associates stands by with an optimal solution. GORE High Performance Aerospace Wires feature proven electrical and mechanical durability to ensure EWIS reliability over time.
ENSURE RELIABLE AIRCRAFT ELECTRIFICATION
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.
Best Combination of Durability & Long-Term Stability
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.
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.
On top of that, our flexible, lightweight design not only eases routing in confined spaces but also won’t increase wire bundle size or add extra weight to the aircraft.
Meet all your electrical wire system needs with GORE High Performance Aerospace Wires that ensure EWIS reliability over time, increase aircraft availability, improve safety and reduce total costs.
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.
