Description
The hub groove and the blade are tightly designed to make the matching between the blade and the hub more precise.
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.
High wind energy conversion rate, increasing annual power generation.
The wind turbine uses a flange connection to make it safer and more reliable.
The surface of the hub is oxidized to make the surface less prone to and durable.
