3. From winding to impregnation – Raúl Morón Ballester 3 Outlook Winding Curing Reaction/Splicing Impregnation Tooling delivery VS. Planning Conclusions

4. From winding to impregnation – Raúl Morón Ballester 4 Winding WINDING MACHINE: Modifications: Update of the control program Shortening of the bench Elevation of the gantry New tension-meter Outer spool holder to support two-layer-winding without internal splice Status: Tension control needs improvement – Not critical

5. From winding to impregnation – Raúl Morón Ballester 5 Winding Winding mandrel and accessories Status: Ready Handling equipment for spool manipulation Status: Ready

6. From winding to impregnation – Raúl Morón Ballester 6 Curing CURING PRESS: Modifications: Hydraulic system has been modified to allow more pressing configurations Update of the control system Resistance heaters instead of warm oil Extension of the bench to hold the outer spool Status: Ready

7. From winding to impregnation – Raúl Morón Ballester 7 Interlayer tool Status: Ready Curing Curing Mould Status: Half shelves shall be modified – Not critical Curing Jacket Status: Ready

8. From winding to impregnation – Raúl Morón Ballester 8 Lifting girder for curing mould Status: Ready Curing - Handling Coil storing tool Status: Ready Coil Handling tool Status: Delivered. Waiting for load tests (W51)

9. From winding to impregnation – Raúl Morón Ballester 9 Reaction Reaction furnace Improvements: - More robust ventilation system - Two oxygen sensors (Reaction Fixture + Retort) Status: Ready

10. From winding to impregnation – Raúl Morón Ballester 10 Reaction Reaction mould Status: Some blocks to be re- done. Delivery end of December - Argon flow is done from mid-plane to poles instead of axially. - The blocks rest directly on the base plate instead of the seal plates

11. From winding to impregnation – Raúl Morón Ballester 11 Reaction - Splicing Lifting tool for mould Status: Ready Splicing tool Status: Manufacturing launched (in-house)

12. From winding to impregnation – Raúl Morón Ballester 12 R-S-I Handling Rotating table for Winding – Splicing - Impregnation Status: Offers received, contract to be placed on W51. Delivery: Mid-March

13. From winding to impregnation – Raúl Morón Ballester 13 Impregnation VACUUM PRESSURE IMPREGNATION SYSTEM Characteristics: Pressure difference injection or dosing pump injection Mixing and outflow reservoirs outside the vacuum chamber Possibility to apply pressure up to 5 bar in each of the reservoirs independently Tilting of the chamber up to 18 degrees Auto-cleaning Status: Technical documents approved. Components ready by first week of January. First injection tests end of January. Machine commissioned: end of March. Credits: Elytt Energy

14. From winding to impregnation – Raúl Morón Ballester 14 Impregnation Impregnation mould Status: DO launched Expected end of March Resin injection can be done from base to top or axially (Axial method has been the usual up to now, but radial method is being tested due to its scalability)

16. From winding to impregnation – Raúl Morón Ballester 16 Conclusions The process has been proven successful up to curing. The reaction and impregnation changes always allow a fall-back solution. Tests are in progress to validate the concepts. The delivery of the missing tooling/machines does not interfere with the planning.
