Video - What are all these wires for ?

- By

Passengers can’t see them, even though they are everywhere. The wiring in aircraft varies according to the plane’s function, but they are found in the wings, the fuselage and even the nose. But what exactly is their function?

More surprisingly, thanks to their electromagnetic sheath wiring protection, there are also cables that protect the aircraft against lightning. In this specialized factory, they produce wiring from A to Z on these tables, called "jigs" where we find the layouts to be followed. But before that, the cables are cut to the required length, and it’s only then that the nimble little hands get involved.

The final wiring is, in some cases, protected by carbon or copper in this workshop, where the bobbins never stop turning.

Last step before shipment to the customer, is the electrical test. Objective: To verify that the power goes through the cable, it’s the least we can do. Meticulous work. To produce all the 400 wires and cables necessary in an A380 for example, thousands of hours are necessary. And placed end to end, they would measure 400 km in length.
