Doubling voltages for aerospace cables

Foiling electrical discharges

The aerospace industry is constantly looking for ways to lighten cable weight while doubling operating voltage in aircraft. However, in non-pressurized conditions, partial discharges can erode traditional insulation. Nexans new composite insulation for airborne energy cables eliminates this danger.

Direct input

Scientific simulation studies showed exactly the stress our cables were undergoing in actual in-flight conditions, and this was the basis of a new insulation patent. The direct input of R&D into design and process is what made it possible for us to advance the state-of-the-art in record time.

Conception leads to creation

At the customer's request, we conducted preliminary tests replicating temperature and low-pressure conditions of actual high-altitude flight. We wanted these tests to be representative, repeatable and reproducible. In our labs, we studied design parameters, including core cross-section, insulation thickness, the airborne environment and resistance to partial discharges, which were later checked and confirmed. Further development mapped out all possible aircraft configurations for this type of cable. This scientific approach generated results far beyond incremental empirical methods.

Cartesian method

Descartes started his line of reasoning by doubting everything, so as to assess the world from a fresh viewpoint, clear of any preconceived notions. He was convinced that this would lead to new insights that would drive innovation. This same scientific method led us to develop a new patent to benefit our aerospace customers. By reinforcing in-flight security, it brings a new advantage in a demanding market. It also proves that applied research upstream coupled with technical knowhow during process is a sure way to shorten development time and refine traditional products.
