Double wound electrical transformers are designed to be for Delta/Star connections unless otherwise requested. Primary and secondary voltages are to customers specifications.
All of our three phase electrical transformers:
- Have high grade copper windings to BS60317, finished by varnish impregnating.
- Core's have electrical steel laminations to BS/EN10165/10107.
- Have double wound connections. Delta/Star.
- Terminations are to Klippon terminal blocks or nut and stud connections.
- Cases are steel ventilated case for indoor use. Wall or floor mounting. Cable entry via conduit entry and exit holes.
Auto-wound electrical transformers are manufactured as a 3 phase step down electrical transformer to reduce 415 volts 3 phase down to 380 volts 3 phase. Other ratios are available on request.
