Nordex S70 and Nordex S77

Product catalog summary
Overview: The document provides detailed technical specifications and features of the Nordex S70/1500 kW and S77/1500 kW wind turbines, designed for optimal performance in various wind conditions. Both models incorporate advanced pitch technology and are built for reliability and efficiency.
Specifications: The S70 features a 70-meter rotor diameter, while the S77 has a 77-meter diameter, both utilizing pitch power regulation. They are designed for a service life of at least 20 years and are ISO 9001 certified. The turbines operate with a variable rotor speed and have a cut-in wind speed of 3 m/s.
Design and Technology: The turbines use a three-stage gearbox and a double-fed asynchronous generator for efficient power conversion. The control system is microprocessor-based, allowing for remote monitoring and control of over 300 parameters. The nacelle and tower designs are optimized for durability and ease of maintenance.
Reliability and Maintenance: The turbines are designed for low maintenance with features like maintenance-free blade-adjustment drives and easily accessible control cabinets. They include redundant safety systems and remote monitoring capabilities to ensure operational reliability.
Environmental and Noise Considerations: The design minimizes environmental impact with enclosed systems to prevent oil leaks and noise reduction measures such as helical gearing. The absence of rotating hydraulics in the hub further enhances environmental sustainability.
Performance Data: Power curves for both models are provided, showing power output relative to wind speed. The S70 and S77 are optimized for different wind conditions, with the S77 being more suitable for areas with lower wind speeds.
Global Presence: Nordex has a worldwide presence with offices and subsidiaries in multiple countries, ensuring global support and service availability.
