Realizing the dream of clean and infinite energy
We lead the way to a brighter future. While enabling renewable energy system,
Greenable contributes to building a sustainable and stable energy market.
Wind power generation refers to the use of the wind to turn the generator (wind turbine), thus generating power. Regarded by many countries as a clean and relatively cheap energy source, it has been widely adopted all across the globe. These days wind turbines are expanding their locations to include the sea.
The majority of wind turbine towers and foundations are constructed with steel plates. Specifically, steel plates adhering to the EN10025 standard are frequently selected for wind power infrastructure. POSCO's latest steel offerings outperform traditional steel products, playing a pivotal role in diminishing the thickness and overall quantity of steel required for such wind structures.
The turbine motor is a component that transforms the rotational force generated by wind acting on the blades into electricity. POSCO's high-quality NO is predominantly utilized for this part. POSCO's Hyper NO exhibits consistent magnetic properties regardless of its orientation, making it especially suited for rotational applications. This material not only enhances energy efficiency by minimizing power losses in motors but also sustains stable power output even when the motor's size is downsized.
Bearings, integral to the rotating parts of a wind turbine, are primarily crafted from the "extreme blue bearing steel." These products, derived from steel bars and wire rods, have their attributes and standards managed in compliance with DIN50602.
Hex bolts, which secure the wind turbine to the tower, as well as the bolts that fasten the blade to the nacelle, are manufactured from steel derived from steel bars and wire rods. Their quality and properties adhere to the DIN50602 standards.
Wind turbine towers are cylindrical structures or polygonal posts that support wind turbines. POSCO specializes in supplying steel for the towers. When used to make wind turbine towers on- or offshore, our steel can keep the towers standing still against harsh conditions, whether it is a strong wind, waves, vibrations, shock, low temperatures and so on. Steel intended for large scale offshore wind towers is much thicker and stronger.
In a wind turbine tower, the turbine motor converts the rotation of the blade into electricity. POSCO’s Hyper NO (non-grain oriented electrical steel) is the ideal material for the motor. Hyper NO maintains constant magnetic properties regardless of grain. It is mainly used for rotating parts. It helps reduce the loss of power in the motor to improve energy efficiency. A smaller motor can provide the same level of output as a larger one.
A turbine bearing minimizes the friction of a rotating shaft, with PosWIND, POSCO made bearing steel, being used for this application. PosWIND features highly improved durability to minimize friction of a rotating object and is commonly used for rollers within gearbox bearings. Bearings made of PosWIND experience little wear, crack or deformation over time.
