JBE Service installed new aviation lights at Ristiveto wind farm

JBE Service performed the installation of new aviation lights at Ristiveto wind farm in Ristivuori, Merijärvi. Six SWT 2,3 wind turbines were originally equipped with aviation lights which were according to the flight obstruction permit granted by TraFi, and which were also found disturbing by the people living nearby especially during cloudy nights.

Wind farm's owner Perhonjoki Oy decided to change the aviation lights to less disturbing when TraFi published the new instructions regarding aviation lights of wind turbines.The most essential change is that during nights the lights are not blinking, but they are replaced by steady red lights. In addition, tower aviation lights had to be installed. As drilling holes to the tower is not recommended, a magnet attachment system for the tower aviation lights and their cables was designed by Puhuri Oy's Timo Annola in cooperation with Hannu Peltomäki Oy.

Installation works were challenging due to cold and windy weather, but the works were finished before Christmas and Ristivuori area got their red Christmas lights and Puhuri Oy has received positive feedback on the aviation light change.
