Wind power generation has extremely high requirements for bolt connections, and the technical characteristics of wind power fasteners are high strength and high precision grade. It needs to bear a variety of alternating loads. In addition to the axial pretension tensile load, it is also subject to tensile alternating loads, transverse shear alternating loads, etc. The application environment is harsh, which faces long-term and extreme working environment temperatures of -40°C~100°C. Wind farms in some areas, especially offshore wind farms, also face high humidity and high salinity erosion.
We have taken necessary measures in raw material performance selection, structural design, manufacturing process, manufacturing management, testing, and on-site assembly to ensure the reliability of wind power bolt connections.
JNZC has rich experience in manufacturing and supplying Tower Bolts, Nacelle Bolts, Blade Studs, and other wind power fasteners. Four of the world's top five wind power equipment manufacturers are our stable cooperation customers.
