Because of its position at the rear of the nacelle, the transformer is actually exposed to high levels of vibration, considerably stressing the transformer bracket. If the transformer bracket should break, the five ton transformer can tilt or hang on one side.In order to improve the stability of the transformer brackets in Vestas V80 VCS, V90 2.0MW and V66 turbines, Availon has developed a new upgrade.
Besides from providing general reinforcements, the design developed by Availon makes use of the previously unused considerable carrying capacity of the crane runway in the nacelle. Using steel rods, the bracket is tensioned crosswise to the crane runway, increasing the load-bearing capacity of the transformer bracket and thus achieving a permanent stabilization against vibrations. The upgrade is available as of immediately.
