BMG’s toroids are single and three-phase transformers from 5,000 VA to 50,000 VA. Conventional 50 KVA marina substations weigh around 400 lbs and for floating docks the weight is 275 lbs. This line of dry-type single-phase and three-phase low voltage (<600 VAC) high power transformers may be used individually or grouped together in Marina Substations and industrial distribution applications with power ratings up to 200 KVA single phase and 150 KVA in three phase configuration. The three-phase transformers include input/output voltages 480 VAC Delta –208V Y/120V, 240V/120V at 60 Hz or 1:1 ratios. Primary taps are optional.The weight and size reduction facilitates handling and installation also in industrial distribution transformer applications.
Other applications include industrial distribution transformers, where the lower weight and dimensions facilitates 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% higher efficiency than the conventional type because of its construction with the copper windings covering the entire core area.
