The R&D team of LZ Blades owns more than 20 years experience in design and manufacture of composite products. The team finished more than 40 types of blade technology introduction or joint design and finished more than 20 types of blades design and validation independently.
With 9 facilities all over, the manufacturing capability of LZ Blades exceeds 3000 sets per year. Intelligence devices such as semi-automatic grinding machine, ultrasonic testing equipment, pipe robot, and etc. are applied for the improvement of manufacuturing efficiency. This also makes LZ Blades China's top manufacturer in automation level.
Quality determines the life span of a blade. LZ Blades ensures our quality from the following perspectives, materials management system, countinous imported material inspection, blade reset control checks, plus predetermined stopping points for check during manufacturing.
Trouble-free operation is key for a wind turbine to capture maximized energy. Therefore regular maintenance of rotor blades during their life span is recommended. This is the concern and we care what you need.
With the concept to ensure the durability of rotor blades while optimising the operating costs at the same time, the operation and maintenance team of LZ Blades provide high quality service at most reasonable prices. Up till now, we have provided services for 16,000 sets of blades in more than 400 wind farms. The team keeps working hard on the damage identification and maintenance of blades in all harsh conditions of both onshore and offshore.
The trouble free operation of wind turbine is the key to capture the maximum wind energy. Therefore, we recommend regular maintenance of the blades. This is your demand, and we care about your demand.
