POSCO can help deliver an access to clean and inexhaustible energy sources.
POSCO’s steel products will play a pivotal role in the upcoming era of clean energy as they can be used in the production, transport, storage and consumption of energy.
Wind Power Generator
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.
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.
