Amphenol's Unique Raceway Attachment Improves Airplane Wire Installation

Body Structure Uses Solvay's KetaSpire® PEEK for Strength, Chemical Resistance, and Long-lasting Performance

ALPHARETTA, Ga. – Amphenol Pcd, a leading manufacturer of interconnect products for military, commercial aerospace and industrial applications, has developed a unique raceway attachment which significantly improves wire installation during airplane construction. The raceway attachment features a body structure made of KetaSpire® polyetheretherketone (PEEK) resin from Solvay Specialty Polymers for high strength, excellent chemical resistance, and exceptional long-term performance in hot-wet environments.

Amphenol's novel attachment for aircraft wiring installation is a high-strength tool-less option that improves efficiency, minimizes error, and speeds installation, according to Victor Muller, Commercial Air Business Manager for Amphenol Pcd. "KetaSpire® PEEK delivers a high level of performance in terms of heat and chemical resistance that is required in this demanding aerospace application," said Muller. The custom-designed raceway attachment is currently specified on Boeing's 777 airplanes.

The body structure made of KetaSpire® PEEK resin holds the wire harness assembly securely and is attached to a rail which is situated on the airframe. The injection molded body structure is a three-part assembly that includes a body, pin, and adapter that are snap-fit together. The entire structure made of Ketaspire® PEEK measures 3.5 inches by 2.0 inches by 2.5 inches (8.9 cm by 5.1 cm by 6.4 cm). The newly designed raceway attachment is installed in multiple locations throughout the airplane during construction.

Along with KetaSpire® PEEK's performance attributes, the lightweight material can reduce part wall thickness and provide additional weight savings.

KetaSpire® PEEK is one of the industry's most chemically resistant plastics and offers excellent strength, superior fatigue resistance, and a continuous-use temperature up to 240°C (464°F). Glass fiber-reinforced and carbon fiber-reinforced grades provide a wide range of performance options for demanding applications.
