Application of induction heating in the wind power industry
ZHENGZHOU KETCHAN ELECTRONIC CO.,LTD is China’s leading supplier of heating solutions in the renewable energy field. Our technology has already made a huge contribution to the efficiency, safety, and profitability of the wind turbine industry – making the manufacture and maintenance of turbines a clean and green process.
Clean and green process：
Induction heating is essentially a cleaning process. It is more energy efficient and environmentally friendly than other heating alternatives. It emits no carbon dioxide. It eliminates open flames, reduces the need for fuel transportation, and promotes safer and healthier workplaces. Product quality and process consistency are critical to the wind turbine industry, which is why accurate, repeatable, and contact-free induction heating has become the standard for wind turbine manufacturers and their suppliers. Wind turbines are exposed to harsh weather conditions, so they must be able to withstand strong winds, especially in harsh offshore environments. Rotor bearings and large gears must be custom hardened to withstand heavy loads and punishing torques, and some high quality mission-critical components require hot fitting, brazing, and preheating.
Almost every part of a typical modern wind turbine uses induction heating.
