Cables, Wires and Accessories for Aiport Infrastructure 400 Hz
All over the world, robust cables are lifelines for aeroplanes on the ground and as a result, the power supply cables for the aeroplanes must be specially designed. At busy airports, the cables are pulled in and out 10 times a day and frequently dragged harshly over rough concrete. In demanding continuous use at the airport, the cables last for around three years or 10,000 aeroplane turnarounds. This explains the important role that robust cables play in Airport Infrastructure.
At Frankfurt airport, a Boeing 737 slowly rolls into the parked position at the gate as if drawn in by its yellow guideline. As soon as it stops, the pilot switches off the engines. At this point, the aeroplane is dependent on external power sources. A member of service staff pulls a flexible, four-conductor yellow cable under the plane from a coil hanging from the jet bridge. He then opens a flap on the bottom front section of the fuselage and uses both hands to push a black plug into the 400-Hertz socket. This so-called 400-Hertz plug and the cables connected to it are the lifeline for all the electrical systems on the aeroplane while it stands at the gate.
At HELUKABEL, we offer 400 Hz cables that are used to supply power to aircraft (on-board power), data processing systems, radar stations, radio stations, etc. For safety reasons, 400 Hz cables are used to connect data processing systems, radar systems and communications systems to uninterruptible power supplies. Such power supplies prevent a total failure of power and compensate for frequency and voltage fluctuations, suitable for installation indoors, outdoors.
