Distribution transformers step the medium-voltage supply down to the 400/230 V level used by buildings and industrial loads. Cast-resin (dry-type) transformers are preferred indoors and in fire-sensitive areas, while oil-filled units serve outdoor and high-rated applications.
Schneider Electric's Trihal cast-resin transformers and Minera oil-filled transformers cover ratings from 100 kVA to 12.5 MVA, with options for K-factor (harmonic-tolerant), low-loss, and IP-rated enclosures.

Yes. K-factor (harmonic-tolerant) variants are offered for non-linear loads, along with low-loss core options for energy efficiency and optional IP31 / IP54 protective enclosures.
Typical applications include indoor commercial and hospital substations, industrial process and heavy machinery, outdoor infrastructure and utility supply, and renewable energy step-up applications.
K-factor variants are designed to tolerate the extra heating caused by harmonic-rich, non-linear loads such as drives and electronic equipment, so the transformer runs cooler and lasts longer on those loads.
Yes. Low-loss core options reduce no-load and load losses for greater energy efficiency, which lowers running costs over the life of the transformer.
Cast-resin transformers can be supplied with optional IP31 or IP54 protective enclosures, while oil-filled units are sealed for outdoor and high-rated applications.
