Founded in 1986, TDA Lefébure has developed an airport activity, specialized in the integration of 400 Hz power supply for the aerospace and military sector.
TDA Lefébure is the sole distributor of 400 Hz Studer cables for France.
Thanks to a large team of specialized engineers and technicians, TDA Lefébure ensures the maintenance of all equipment it has provided and installed, as well as further 400 Hz equipment and 50 Hz Uninterrupted Power Supplies.
Its « Skypit » cable retriever, launched in 2009, has been selected by a large number of airports amongst the largest international airports. This exclusive system, protected by several patents, stores and protects the cable, caring for optimal security conditions, and reduces strongly the need for maintenance, for the cable as well as for the retriever itself.
TDA Lefébure partners with numerous manufacturers of 400 Hz equipment in order to offer to its customers the highest technical solutions and the best service in terms of logistics, quality and reactivity.
Our activities include :
• The systems to store and protect the aircraft cables: "Skypit" cable retrievers, coilers, hatch-type and Pop-up pits, as well as multi-energy pits for the maintenance hangars and the tarmac ;
• The converters on trailer ;
• The conception, integration and delivery of complete 400 Hz power supply systems, centralised or decentralised, from the 50 or 60 Hz supply until the aircraft connector or the avionics workshop bench;
• The customer service, from the conception to the maintenance, of equipment supplied by TDA or by third party manufacturers;
• The test and maintenance equipment such as test boxes and cases, test connection plugs, etc…
