The right cable protection is essential in the aerospace industry. It ensures the safety and reliability of aircraft and spacecraft as well as safe processes on the ground. Electrical systems used for power supply, control and data transmission are often exposed to extreme loads. Techflex offers customized products that meet these special requirements. Our products offer reliable protection for wires and cables in the aerospace industry.

Like every industry, the aerospace sector has individual requirements for materials. However, these are more specific than in almost any other sector. The cables and wires used in the aerospace sector are exposed to extreme temperature fluctuations, intense vibrations and electromagnetic interference. Special challenges therefore make the topic of cable protection for the aerospace industry exceptionally demanding. At Techflex, we know these special requirements down to the smallest detail.

Vibrations and strong shocks occur primarily during take-offs and landings. Cables must therefore be flexible and robust enough to withstand these mechanical stresses without breaking or losing performance. Extreme temperatures and constant temperature changes are also anything but a rarity in the aerospace industry. From the cold at high altitudes to the heat from engines: cables must be able to withstand temperature fluctuations of several hundred degrees without losing flexibility and reliability.

The power supply systems in airplanes and spacecraft are central components of the on-board electronics. Cables leading from engines and batteries to control and drive systems require special protection to withstand overloads. This is the only way to avoid dangerous short circuits. 

Insultherm® AERO is a fiberglass insulating sleeving with different wall thicknesses that is ideal for high and low voltage applications. Its high temperature resistance and flexibility make it particularly suitable for the tight radii of high-voltage applications in electric vehicles. It is not flammable or fusible. Insultherm FIA corresponds to the insulating material “Fireflex” from the USA and complies with the applicable AS1072 standards.

Halar®, for example, is a self-extinguishing material for braided hoses. It was specially developed for applications that require high temperatures and chemical resistance. The fire-retardant and smoke-suppressing material Halar is particularly suitable for cables in sensitive areas, such as near jet engines. It is also resistant to a wide range of chemicals. 

Vectran® has exceptional material strength and temperature resistance. This makes Vectran high-performance fiber the ideal choice for protecting cables in aircraft and spacecraft. 

Flexo® PFA (Teflon) is also resistant to heat and chemicals and at the same time has low outgassing. This makes this material particularly suitable for plenums.

Another plus point of the Techflex range for cable protection for aerospace applications: Lacing tapes (military specification MIL-T-43435) made of different materials and various coatings bundle both stranded wires and heavy power cables. They have good resistance to liquids and solvents, which are mainly used in aircraft engine applications. They are also particularly temperature-resistant - both in extreme cold and heat. 

Various systems on board generate electromagnetic fields and vibrations that can affect signal quality. Effective protection against EMC is crucial to prevent data loss and interference, such as interruptions to data transmission. In short, communication in the aerospace industry requires interference-free, secure data transmission and sensor technology. Techflex offers solutions that are equipped with metal braiding and foil shielding to provide optimum protection for sensitive signals. This allows the systems to work undisturbed and without errors.

Flexo Shield®, for example, is a very lightweight, high-performance EMC conduit that enables interference-free data transmission thanks to effective shielding against electromagnetic influences. The material is ideal for cable bundles in energy-intensive areas and protects transmitted data - for smooth communication in aerospace applications. Thanks to its high flexibility, it adapts to the movements of the cables while remaining mechanically stable.

The cable protection solutions from Techflex make a significant contribution to the safety and reliability of aircraft and spacecraft. By using specialized products such as Flexo Shield, Halar and Vectran, Techflex offers optimal protection for electrical systems in extreme environments. We offer customized solutions in the aerospace industry that combine safety, efficiency and durability.
