High Power Torodial Transformers from Bridgeport
High-power toroid transformer.
Shelton, CT — Bridgeport Magnetics Group Inc. has introduced a line of dry-type single-phase and three-phase low voltage (<600VAC) high power transformers from 5,000 to 50,000VA. The transformers can be used individually or grouped together in Marina Substations and industrial distribution applications with power ratings up to 200kVA single phase and 150kVA in three-phase configuration.

The three-phase transformers include input/output voltages 480VAC Delta — 208V Y/120V, 240V/120V at 60Hz or 1:1 ratios. Primary taps are optional.

For Marina Substations, the transformers are housed inside sleek enclosures of 316L stainless steel. With considerable weight savings of 30 percent from using toroidal power transformers instead of the conventional stacked lamination type, these high power toroids are particularly suited for installation on floating docks. Other brands of a typical 50kVA substations with conventional transformers weigh around 400 lbs. With BMG's power toroids, the weight is less than 275 Lbs.

Other applications include industrial distribution transformers where the lower weight and dimensions facilitate both transportation and installation.

In addition to weight and size reduction the toroidal transformer design offers low no-load losses meeting NEMA premium guidelines. In addition, toroidal power transformers generate lower operating temperature and 15 to 30 percent higher efficiency than the conventional types because of their construction with the copper windings covering the entire core area.
