Aircraft Cable Harnesses
SMI’s technology enables electrical wiring interconnect system (EWIS) to be deployed on airframes where they will see the worst environmental conditions such as the undercarriage, fuel tanks or landing gear. Having a leak-free reliable electrical connection enables a move away from hydraulic actuation to electrical harnesses with considerable weight saving.
Cables need to be routed through complex paths in the airframe, around corners and through holes. To tolerate this well, special abrasion resistant cable jackets are used for aircraft cables and every component on the airplane must be non-flammable. The reliable SMI penetrator product set enables cable routings through fluid and fuel tanks to exploit advantages or routing and weight saving.
In addition to resistance to shock, vibrations, corrosion and extreme temperatures, strong electromagnetic protection and unparalleled sealing are able to deliver high data rates with reduced weight profiles. Designed to resist the aggressive fluids typical in the aviation space including chemicals, fuels and hydraulic fluids SMI moulding technology also provides complex breakout options and over moulding of components for fit and forget reliability.
