Solution For Wind Turbine

Key points of installation:

Two obstruction lights should be installed on the top of nacelle, the spacing between the two lights should be bigger than the width of the rotor blades.

Obstruction lights on the same wind turbine shall flash simultaneously.

When H＜45m, low intensity obstruction lights type B or medium intensity obstruction lights type B shall be located on the top of nacelle.

When 45≤H＜105m, medium intensity obstruction lights type B shall be located on the top of nacelle.

When 105≤H＜150m, medium intensity obstruction lights type A shall be located on the top of nacelle.

When H≥150m, high intensity obstruction lights type A shall be located on the top of nacelle, low intensity obstruction lights type E shall be located at intermediate levels.
