A coil of insulated conductor wire wound around a magnetic core to create or respond to magnetic flux in transformers and reactors.
A winding is a coil of insulated conductor wound around a magnetic core to form the primary functional element of a transformer or reactor.
Types of Windings
- Primary winding — connected to the energy source
- Secondary winding — connected to the load
- Tertiary winding — for auxiliary purposes
Insulation Classes
- Class B (130°C) — polyester-based enamel
- Class F (155°C) — modified polyester
- Class H (180°C) — polyamide-imide
