Hamburg, 29 August 2019. The independent certifying agency TÜV SÜD Industrie Service GmbH has awarded the worldwide valid IEC type certificate for the N149/4.0-4.5 turbine from the Delta4000 series.
The type certificate officially confirms that the theoretical design calculations for the N149/4.0-4.5 done by the Nordex Group reflect the figures for the turbines actually measured in the field. This is in fact a confirmation of the power performance and mechanical loads during operation as well as the lifetime of the turbine type under different operating modes. Likewise the NR74.5 rotor blade was successfully certified for a lifetime of minimum 20 years on the basis of a dynamic, physical rotor blade test.
The certification is based on a comprehensive measuring and validation programme over the past twelve months with the N149/4.0-4.5 turbines installed in summer 2018. TÜV SÜD had already issued the “Statement of Compliance for the Design Evaluation” for this turbine type in September 2018. This design evaluation was one of the first preconditions for issuing the present type certificate.
