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.

FAQ

Frequently asked questions

What do MV distribution transformers do?

They step the medium-voltage supply down to the 400/230 V level used by buildings and industrial loads.

What rating range is covered?

Schneider Electric's Trihal cast-resin and Minera oil-filled transformers cover ratings from 100 kVA to 12.5 MVA.

When should I choose cast-resin versus oil-filled?

Cast-resin (dry-type) transformers are preferred indoors and in fire-sensitive areas, while oil-filled units serve outdoor and high-rated applications.

Are there options for harmonic-heavy loads or efficiency?

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.

Where are these transformers typically applied?

Typical applications include indoor commercial and hospital substations, industrial process and heavy machinery, outdoor infrastructure and utility supply, and renewable energy step-up applications.

What does the K-factor rating mean?

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.

Are low-loss, energy-efficient transformers available?

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.

What protective enclosure options does NLC offer?

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.
