Refers to its tower. The lower part of the tower is made of concrete and the upper part is made of steel tower. The specific height depends on the situation.
The mixed tower has a fully prestressed concrete tower. Compared with flexible steel towers, this tower has greater overall structural rigidity and a larger damping coefficient, ensuring that the unit will remain stable during installation and throughout its life cycle. The small amplitude of the unit ensures a stable windward angle of the impeller system, more stable power generation and greatly reduces operation and maintenance costs.
The tower can be divided into reinforced concrete and steel structures according to materials. The all-steel structure tower has a low natural vibration frequency and is also called a flexible tower. Part concrete and part steel structure is called a mixed tower.
This kind of tower export requires production qualifications.
Wind power towers are an important part of the wind power generation system, and their quality directly affects the safety and reliability of the wind power generation system. Therefore, exported wind power towers need to pass strict quality inspections. Only by ensuring that its quality meets international standards can it obtain export qualifications.
The production qualifications for the production and export of wind power towers include ISO9001 quality management system certification, OHSAS18001 occupational health and safety management system certification, etc.
