The blade is 76 meters long. It is a new onshore large-blade product launched by SUNRUI Blade for the era of parity. The rated power of the blade is 5.0MW-6.XMW.The SR156 R&D team solved various problems in the R&D process through in-depth planning, careful experiment, and pre-judgment, finally successfully completed the design and production of the blade.

The blade realizes the maximization of a variety of new structures, new technologies, new processes, and new materials; it covers the latest technology of integral pouring molding of pultruded plate girder and shell, and structural forms such as single web in the cavity; and expands a new infusion resin, clamping adhesive, sandwich material and root connection bolt system. Every new design, new material and new process is a new challenge. Through detailed theoretical analysis, combining with a large number of experimental demonstrations, the project team steadily advances and continuously overcomes every difficulty. The successful test of the product verifies a number of new process technologies, enriches the raw material database, further consolidates the independent design capability of SUNRUI Blade, and lays a solid foundation for the future development of the wind power blade industry.
