Product OverviewThis product is a high-precision cast iron test platform exclusively customized for the wind power industry. It is the core benchmark equipment for R&D, component inspection, assembly, commissioning and performance verification of wind power equipment. Made of high-strength cast iron, it supports modular seamless splicing and is suitable for onshore/offshore wind turbines from 2.0MW to 15MW. It fully meets the adaptation requirements of mainstream existing and new models in the industry.
The product complies with both Chinese GB/T standards and EU DIN/EN standards, and can be directly sold and used in the EU market with complete compliance. It is widely used by wind turbine manufacturers, O&M service providers, third-party testing institutions and research institutes.
