Abstract
A structure for consolidating large turbine generator end turns while providing for thermal compensation includes a decoupled brace that is located radially outside the end turns and has a bottom piece secured to a bracket secured to the core as well as a top piece adjacent the coil and an intermediate decoupler between the two that includes elastomeric material for cushioning as well as a slip layer for allowing free axial movement between the top and bottom pieces of the brace. Additionally, keyed strain blocks may be utilized between top and bottom coils of the assembly for greater consolidation.
