     wind turbine foundation anchor cage淖毛湖新疆哈密三塘湖项目1

    An Anchor cage is composed by anchor bolts, 2 anchor plates(templates)-upper template(temporary template, upper anchor bolt), lower template(lower anchor bolt), Steel Nuts, seal nut(nylon nut), Washers(gaskets), adjusting feet assemblies, splice plates(connecting plates), PVC tubes, corrosion protecting grease, fabric,HDPE bolt caps(bolt hat) etc



    Anchor bolts are the most important part in this assemblies in WTGS(wind turbine generator system) since this part will bear the pre-stress, pre-tensioning forces, and take responsibility for the stability of the whole turbine or tower. Our manufacturer have the most advanced facility of heat-treatment of steel round bars, which means the pre-stress bearing capacity, tensile strength, yield strength abilities are much higher than the international standards. That is the reason why many world-wide companies choose us.
