Ved opfindelsen tilvejebringes mulighed for at opspænde vindmøllevinger ved hjælp af spændkabler. Opspænding kan udføres før udstøbning af vinge eller efter vingens fabrikation. Der er mulighed for at variere opspændingen i vindmøllevingen efter vingens aktuelle ydre belastning. Variationen kan tilvejebringes ved en mekanisk eller hydraulisk opspændingsmekanisme i nacellen eller lignende. De opspændte vindmøllevinger vil være kendetegnet ved, at stabiliteten og stivheden af vindmøllevingen kan forøges/varieres,The invention provides the possibility of clamping wind turbine blades by means of clamping cables. Clamping can be performed before casting the blade or after the blade fabrication. It is possible to vary the tension in the wind turbine blade according to the current external load of the blade. The variation can be provided by a mechanical or hydraulic clamping mechanism in the nacelle or the like. The clamped wind turbine blades will be characterized in that the stability and stiffness of the wind turbine blade can be increased / varied,
