The concept is as simple as it is effective: instead of complicated installation work by hand and costly test runs on site, Weidmüller makes it possible for the Nordex tower supplier to install all lighting and power systems in the tower segments quickly and easily before they are erected.
Power feed box in the wind turbines – assembled in line with the specific requirements of Nordex
The installation components for the different segments of the eight towers are delivered to the tower supplier Reuther as individual, easy to install kits. In addition to the completely pre-assembled LED sets with unique EPLAN based labelling and an installation plan, the kits also come with a power feed box. Individually tailored to Nordex requirements, this particular solution component reliably supplies current to the lights and outlet boxes in the respective segments.
A special highlight: in the event of a power failure, the integrated control unit triggers flashing lights throughout the tower, immediately alerting the service personnel. Information on changing conditions is simultaneously transmitted to an external maintenance unit.
“The supplied installation drawings are so simple and clear that the installation time spent in the tower segments could be considerably reduced,” said Ralf Harder, Senior Engineer of Electrical Drives and Design at Nordex.
The low power consumption and durability of the Weidmüller solution helped to increase the efficiency of the wind turbines. “The tower lighting meets our expectations. For example, the lux readings on the individual rungs of the tower ladder are ten times the required value“, says Nordex Quality Manager Michael Portig with regard to the impressive brightness measurements obtained in one of the completed towers.
Although the LED solution was conceived specifically for the current project, its universal nature enables Nordex to equip all of its tower variants in the same way. This means that the potential of the plants can be exploited at a global level.
