Product description

Ripple springs for consolidating of coil and slot wedge in slot

Applications

High voltage (hydro) generators based on Resin Rich technology

Technical description

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.
