Support grows for contactless technology in airfield lighting

TKH Airport Solutions has supplied its Contactless Energy & Data Distribution (CEDD) airfield lighting and low-voltage infrastructure to Lelystad Airport in the Netherlands to replace its conventional airfield ground lighting system.

Unlike traditional solutions, CEDD does not require constant current regulators (CCRs), transformers, primary, and secondary cables to regulate the power supply. It relies on a dedicated cable that transmits energy to individual lights using induction technology, which then sends data to the central base station.

TKH director Sander Doves told Jane’s the energy usually needed to power a transformer is no longer required. “When you transition from legacy halogen to LED lights, broadly speaking you can reduce power consumption by about 50%,” he explained. “We calculate we can add a further 15% with CEDD technology. The most dramatic change is between halogen and LED. But these systems still use 6.6 AMP circuits and rely on transformers. Our solution removes that completely.”

Lelystad completed a major runway extension and airfield ground lighting programme to become the first airport to equip its entire runway and taxiway with contactless technology in 2018. It is one of a growing number of airports to choose contactless technology to take advantage of lower power consumption and safer airfield operations. Lelystad Airport is appointed by the Dutch government to handle overflow leisure traffic from Schiphol. It will probably open operations in 2020 for large commercial air traffic.

Since TKH first introduced CEDD technology in 2017, installations have been carried out at Amsterdam Schiphol (Heliport), Vancouver International (a stop bar and taxiway lead-on and lead-off lights), and Geneva International (taxiway lighting). Doves said major European airports are also close to selecting the technology. “Airports are not just looking at the capital investment but the operational aspects. It enables you to move from corrective to preventative maintenance. The system is a whole lot smarter,” he added.
