Maintenance-free tower lighting in wind turbine generators

04 July 2016

In order to ensure the safety of employees in wind turbine generators, the towers must be illuminated safely.

To this end, Phoenix Contact offers a tower lighting system using maintenance-free LED lights. The LED lights are supplied centrally by an uninterruptible power supply (UPS) installed in the tower base. Even before climbing the tower, the service technician can find out the state of the UPS and the batteries. Easily installed using the QPD quick connect fittings and pre-assembled cabling.

The powerful LED modules conform to the relevant standard EN 50308. They provide good luminous intensity even at low temperatures. Thanks to a service life of 50,000 hours, the lights do not generally have to be replaced. Due to the low current consumption of the LED technology, the lights also function as emergency lighting. In the event of power failure, the lights continue to be supplied via a central battery. The luminosity is then maintained at 50 percent. There is therefore enough light still available in the wind turbine generator for the service technician to safely descend.
