It was amazing to see how 2.5 Tonne 23 metre long blade is manufactured in the plant. Made of composite material(resin), blade has three parts separately moulded- Spoiler,Middle and Root. Layers of matts are spread, bonded and heat treated to form these parts.Blade manufacturing is a complex activity.
Strength is achieved by 2 I sections.and continuous stran mesaurement transducers are provided forcondition monitoring during service.It takes 24 hours to make one complete blade, which is thenmounted on sleeve bearings of hub.
Rotor plant is seperateand eually exciting to see.60 pole shoe rotor generates 600V.Control boxes such as relay box, battery box and lubrication box were nicely placed. Generator weight 36 Tonnes.
Kudos to ENERCON for such well maintained plant.
