The new Siemens Gamesa 5.X onshore platform has its roots in Siemens Gamesa technology, synonymous with innovation, know-how and reliability accredited through experience. The Siemens Gamesa 5.X platform incorporates proven technologies, minimizing risk and guaranteeing reliability for its three new product models: SG 6.6-155, SG 6.6-170 and SG 7.0-170 wind turbines.
These include a doubly-fed generator and partial converter combination, a compact drive train design with a three-stage gearbox, and the use of components widely validated on our platforms. The result is a wind turbine design that gives optimum performance and LCoE.
