Ripple springs for consolidating of coil and slot wedge in slot
High voltage (hydro) generators based on Resin Rich technology
Top ripple springs are used for the consolidation of stator bars and slot wedges in high-voltage generators. The springs ensure constant tension on both stator bar and wedge ensuring good consolidation. Additionally the springs are better resistant to thermal cycling compared to typical slot fillers and ensure that coil and wedge are well consolidated in both cold and warm condition. Top ripple springs also make the placing of stator bars more easy, saving time.
