Copper windings and electrostatic shielding minimize stray losses and insulation stress, delivering longer transformer life and reduced maintenance cycles in high-demand applications such as data centers and manufacturing lines. This translates to lower total cost of ownership and improved uptime across critical feeders. The voltage taps—two at +2.5% and four at -2.5%—enable precise regulation under load swings, supporting PV interconnection, sensitive controls, and distributed generation where voltage stability is essential. With a 112.5 kVA rating, 480 V primary and 208Y/120 V secondary at 60 Hz, this dry-type distribution transformer fits standard three-phase feeders and MCCs, reducing retrofit complexity and enabling rapid deployment. The unit’s 115 °C rise and copper windings provide robust thermal performance in hot facilities, while the electrostatic shield and WS34 weather protection extend outdoor viability and safety. UL Listed and NEMA TP-1 compliant/efficient design ensure compliance, safety, and reliability for modernization programs and regulated electrical environments.
