An electrical generator connection, to connect coil ends, and a method of making the same. A header cap having a spherically shaped portion is brazed to each coil end to be connected. A pair of connector bars, each having a pair of similarly sized spherical seats, receives the spherical portion of each coil end header cap. Electrical and mechanical connection is provided by bolting the two connector bars together.

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.
