The Nordex Group is extending its product portfolio with a multi-megawatt machine in the 5MW class. After the N149/4.0-4.5 and the N133/4.8, the new N149/5.X is the third turbine type in the Delta4000 series.
The N149/5.X is designed for moderate and light-wind areas. Apart from the classic core markets in Europe, the target markets for the N149/5.X also cover global growth regions such as South Africa, Australia and South America. A new gearbox is used and the electrical system of the Delta4000 series is scaled up in order to achieve the high power output in the 5MW range. The electrical system with its double-fed asynchronous generator and the partial converter have been retained. The N149/5.X also uses the N149/4.0-4.5 rotor blade, which further increases the modularity of the Delta4000 product series. The exterior dimensions of the nacelle remain unchanged. The turbine is offered with a wide range of sound power modes. Different tower options are offered for the N149/5.X - up to a height of 164 metres, depending on the market. The turbine options also include a cold-climate version for operation at temperatures down to -30° C as well as an anti-icing system for rotor blades. The turbine is due to go into series production as of 2021.
