Cables (special) Extreme cabling

High performance cables for extreme harsh environment applications

  • Lower temperature limit of -55ºC Upper limit of +250ºC Will Flex at -50ºC
  • Built in clipping points and fixings
  • Light weight with good abrasion resistance and extremely tough
  • Resistant to aviation fuels and fluids
  • High flexing (applications in excess of 250,000 bends achieved)
  • Meets FAR 25 Flammability Requirements
  • Highly accurate and repeatable forms and shapes

Tekdata Interconnections' moulded harness systems offer a different way of providing high integrity harsh environment interconnect solutions.

Wires #8 AWG to #44 AWG, fibre optics and tubes are encapsulated into a protective over-mould material selected to meet the mechanical, environmental and sealing needs of the system. This means that wiring systems can be configured to suit all applications.

Harnesses complex shapes can be constructed from 3D models allowing design teams to form close tolerance harness shapes that fit the product they are building, rather than providing space for loose tolerance circular bundles with indiscriminate bends and fixings. Fixing points can be integrated into the assembly, speeding up installation and reducing fatigue and chaffing on the harness. The harness shape is highly repeatable and close tolerance, enabling repeatability and consistent performance with good aesthetic properties.

Shaped moulded harnesses are available across a wide range of sizes and moulding materials enabling them to be configured for diverse applications. Tekdata “Teksol 340” is a high strength, tough and flexible material that meets all the above requirements. It is qualified for flight applications and is approved to FAR25 fire resistance. Ridged and semi flexible forms using epoxy based materials can be produced.

A helicopter manufacturer has employed this system to route power and signal wires through the pitch horn and cyclic of a rotor head to the individual rotor blades. This application is one of the harshest environments that a harness can operate in. The harnesses are fully sealed and subjected to continual flexing, high vibration, extremes of temperature (-55°C to +120°C) and must be resistant to fuels, oils and de-icing chemicals.

Uses:
Moving control surfaces, flexing joints, high stress areas, restricted spaces, protection from abrasion, fluid resistance and resistant to installation damage.

Applications:
Airframe, undercarriages, pylon interfaces, robotics, fighting vehicles and security.
