Product Features

The built-in copper sleeve insert of the blade does not damage the nylon fiber when the bolt is tightened, making it difficult to deform or break. The hub groove and the blade are tightly designed to make the matching between the blade and the hub more precise. The surface of the hub is oxidized to make the surface less prone to corrosion and durable. The wind turbor uses a flange connection to make it safer and more reliable. High wind energy conversion rate, increasing annual power generation.
