We4Ce Blade Root Connection

The “We4Ce Blade Root Connection” is an interesting option to increase the length of rotor blades. 35% more bolts at the connection to the turbine hub guarantee a longer blade with a higher annual yield of the wind turbine, compared to the originally used T-bolt technology.

The We4Ce blade root connection is patented and available for M20, M30 and M36 sizes. More than 25,000 turbines worldwide in the range from 1.5MW up till 8MW are installed with the We4Ce technology.

The We4Ce blade root connection is extreme load and fatigue load tested for a 20-25years life-time plan. For all three sizes, the engineering properties are confirmed by a European certification body according to the Guideline for the Certification of Wind Turbines Edition 2010 and in correlation with the latest DNVGL-ST-0376 edition 2015.

The We4Ce blade root connection can be integrated in third party rotor blade designs. In this respect We4Ce have good cooperations with several turbine producers and rotor blade producers in different continents of the world.

Apart from selling such  technology transfers, since 2018 We4Ce also supplies hard-ware components for a consistent and assured quality level which enables producers to concentrate on the assembly in the main mould during blade root production.

The advantages of the We4Ce blade root connection:

  • More bushings/bolts on a smaller root Pitch Circle Diameter
  • Consistent assured reliable quality level
  • Faster assembly in main rotor blade production mould
  • Lower maintenance cost during life time “OPEX”
  • Options to adjust the blades for different loads
  • Certified solution

The services We4Ce offers are:

  • Design technology transfer “license to produce”
  • 180 degrees prefabricated hard ware supply
  • Sub-component supply
