Winding and impregnation
Content:
Coils
- Winding and insulating LV and HV coils for AC and DC motors from round and profile wires
- Winding of HV coils by the Resin Rich method with a discontinuous system (eventual a continuous system)
- Anti-corona protection
- Connecting coils: soft and hard soldering, crimping
- Max dimensions: 1.5 x 0.4 m, 10.5 kV

Impregnation
- By soaking
- Pouring
- VI - Vacuum impregnation
- VPI - Vacuum impregnation with overpressure
- Impregnation varnish Dolphon, Damisol (alternatively Voltatex, Dobecan)
- Regular control of varnish quality (purity and clarity, viscosity, gel time)
- Boiler size: Ø 1.2 m, length 1.3 m, up to 1.5 t, possibility to impregnate rotors as well
