A through bolt is provided for a magnetic core of a generator stator, which is insertable in a bore provided in the stator core lamination for maintaining the tightness of the core components. The through bolt includes at least two longitudinal through bolt elements which are interconnected via at least one connecting element. Further, a method for assembling a separable through bolt for a magnetic core lamination of a generator stator is described. Thus the drawbacks of the prior art are avoided and an improved solution for replacement of the through bolts located under the level of the floor foundation is provided. Further, no special tooling or lifting of the frame are required which makes such replacement easy and cost efficient.
Through bolt (4) for a magnetic core of a generator stator (1), which is insertable in a bore (6) provided in a stator core lamination (3) for maintaining tightness of core components, wherein the through bolt (4) comprises at least two longitudinal through bolt elements (9, 10) which are interconnected via at least one connecting element (11).
Method for assembling a separable through bolt (4) for a magnetic core lamination (3) of a generator stator, the through bolt (4) comprised of several individual elements, wherein the method comprises:
Generator stator (1) comprising a plurality of laminations (3), forming a magnetic core, the laminations each comprising at least one bore (6);
