- First of all, its rigid surface can maximize the friction resistance of the bolt connection. Even if the blade generates huge torque under strong wind, it can offset the tendency of loosening and eliminate the "torque attenuation" caused by deformation of conventional gaskets;

- Secondly, its hardness is much higher than that of metal gaskets. When it is subjected to alternating blade loads and bolt bite forces for a long time, it has no wear or compression deformation, and can continuously maintain the initial tightening pressure to avoid bolt bite slippage or connection breakage caused by gasket failure;

- At the same time, the micron-level flatness can accurately control the bolt fit gap, preventing local stress concentration on the connecting surface of the blade and hub due to uneven stress, and further ensuring the safety of the connection under high torque conditions.
