The transformer is equipped with large external cooling radiator banks and Krenz-Vent forced-air cooling fans, allowing the unit to increase from its 7,500 kVA self-cooled rating to 9,975 kVA with forced-air cooling. This transformer is configured with a 13,800Y\/7,970V high-voltage primary and 4,160V secondary, operating at 60 Hz with a 65°C temperature rise and 6.4% impedance at 85°C. The unit utilizes copper\/aluminum winding conductors and is equipped with five high-voltage tap positions, providing voltage adjustment to accommodate varying system conditions.\u003c!--
