وصف المنتج
500kVA 12kV to 208Y/120 V Three Phase Pad Mounted Transformer with 304 Stainless Steel Enclosure UL Listed
Product Overview
This 500kVA liquid-filled pad-mounted transformer is designed for three-phase step-down distribution from a 12,000V Delta primary to a 208Y/120 V Wye-N secondary. The unit uses a loop-feed, dead-front high-voltage compartment with 200 A load-break components, elbow surge arresters, and oil-immersed fuse protection for medium-voltage cable connection and primary-side protection. Its 304 stainless steel tank, cabinet, and base platform support outdoor pad-mounted installation, while copper windings, a grain-oriented steel core, ONAN cooling, and DOE 2016 / CSA / ANSI-IEEE compliance provide clear specification references for commercial, utility, and industrial power distribution projects.
