Three Phase Auto-Wound Transformers

Three Phase Auto-Wound Transformers

Our 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.

These transformers have a capacity from 2kVA to 100kVA. All units are normally supplied in a suitable indoor ventilated enclosure with cable entry and exits. Open type units can be supplied if required.

All of our Three Phase Auto-Wound Transformers:

  • Have high grade copper windings to BS60317, finished by varnish impregnating.
  • Cores 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.

Transformers may be fully customised to your individual specification.

Designed and manufactured to meet the highest standards needed in industry today.
