Significantly reduced power loss, meeting the top runner energy-saving standards! A compact, earthquake-resistant, and quiet oil-filled transformer for civilian use.
This is an oil-filled transformer for civil demand, widely used in factories, buildings, and commercial facilities. <Features> ■ Improved energy efficiency By fully adopting high-grade low-loss magnetic materials "silicon steel sheets" for the core and increasing the cross-sectional area of the coil conductors, we have achieved significant loss reduction. Total loss reduction amount (compared to our conventional products) TOP ECO2 series: approximately 47% reduction, ULTRA ECO series: approximately 57% reduction * For a three-phase 1000kVA 6kV/210V 50Hz at 50% load rate ■ Enhanced seismic performance By equipping a displacement suppression seat that limits the relative displacement between the transformer body and the panel housing, we prevent ground faults and short-circuit accidents at the transformer terminal during an earthquake. The installation of a damping device further enhances seismic performance. ■ Compact design ■ Reduced noise level
