The N133/4.8 turbine is our highest yielding onshore turbine for strong wind regions with average wind speeds over 8.5 m/s. The turbine has a 78 percent increase in rotor sweep compared to its predecessor (N100/3300) and a power output of 4.8 MW achieving yields that are up to 39 per cent.
For the N133/4.8, Nordex has transferred the rotorblade of the proven N131 to the Delta4000 series. The combination with the N149/4.0-4.5 hub has increased the rotor diameter to 133 metres. The N133/4.8 has a rotor sweep of 13,935 square metres.
The technical innovations introduced with the N149/4.0-4.5, such as improved maintenance concepts, a mobile crane solution and a higher efficiency of the electrical system will also be used in the new turbine to significantly reduce the cost of energy.
Despite its large rotor the N133/4.8 comes with a variety of tower heights simplifying the permitting process at sites that are subject to strict maximum heights.
Fitted with serrations, the rotor blades of the N133/4.8 reduce sound levels to meet the requirements of the local residents as well as the regulatory authorities. At maximum output the sound power of the N133/4.8 remains below 106 dB(A). At the same time, the turbine can also be operated in various sound-reduced modes down to maximum 98 dB(A) if required.
The N133/4.8 is the turbine model for strong wind sites of the Delta4000 series. In developing the Delta4000 series, there was one primary focus: the sustainable reduction of the cost of energy (COE).
