Design of 400Hz systems

TDA Lefébure designs the complete 400 Hz generation and distribution system of the airport or air base, from the building electrical power supply until the aircraft connector.

TDA Lefébure advises you in the best choice for the system architecture, centralised, semi-centralised or decentralised, for an optimisation of the initial cost, the maintenance, the availability and the energetical performance of the installation.

TDA Lefébure elaborates your solution, in partnership with the major equipment manufacturers for electrical energy conversion, transport, regulation and supply to the aircraft.

Focus on ...

FLEX-PIT

Flex-Pit (hatch and pop out) enables aircraft to be connected to the 400 Hz power supply and other utilites in the maintenance hangars.

The “Pop Out” system simplifies access to cables and sockets by presenting them 50 cm above ground.

Once all cables are connected, the Hatch pit can work in closed position.

The manhole, behind the hatch, makes any maintenance fast and without effort.

PCA-PIT

The unique design of TDA’s PCA Pit caters for optimal storage of the hose, easy access to the PCA connection device and maximum protection of the hose, thanks to the tulip-shaped extraction guide.

TDA’s PCA pits are available for flat duct and accordion hoses.

Upon opening the pit, the aircraft connector is presented above ground, at hand level.

B-PIT

With dimensions reduced to the minimum, the B-Pit puts at disposal directly at the aircraft parking position a 400 Hz socket (up to 250 A) for a PCA group or any other equipment requiring a significant electric power.

Once all cables are connected, the Hatch pit can work in closed position.

The manhole (in option), next to the hatch, makes any maintenance fast and without effort.

The B-Pits can be associated in parallel in the same concrete pit, for the supply of different utilities.
