3-Phase Transformer RDST 40 – 630 kVA

Three-phase transformerRDST 40 – 630Three-phase transformers up to 630 kVAInput/output voltage, currents, connections, and mounting according to customer specifications.(Loss-optimized version with grain-oriented Armco-Lec) General:The rectangular core assemblies of our higher-power three-phase core transformers are constructed from alternately layered strip steel. The windings are impregnated together with the core under vacuum and then cured in a drying oven for several hours.Special features of the RDST series: Dry-type core transformers in accordance with EN 61558 / VDE 0570 Designed for maximum efficiency The robust design ensures an almost unlimited service life for the transformers, even under overload conditions Connections up to 415 A via terminal blocks; above that, bolts, busbars, or cable lugs (not dimensioned) Insulation class F Custom design; therefore, dimensions and weights are subject to change Loss-optimized seriesAll models are also available as three-phase economy transformers (for calculations, see the section “Transformers with Economy Windings” in the General Section).*Depending on the design and winding type, all dimensions—especially dimension b—may increase by up to 100 mm for special currents!Dimensions d and e available upon request; insulation class F
