50KVA Single Phase Pole Mounted Transformer

The 50 kVA Single Phase Pole‑Mounted Transformer is a robust, UL‑certified electrical unit tailored for overhead distribution systems in utilities, residential communities, and light‑industrial sectors. Featuring wide primary voltage adaptability—from 2.4 kV to 34.5 kV—it utilizes an oil‑immersed core with ONAN cooling to deliver stable 120/240 V or optional 240/480 V, 347/600 V, or 277 V outputs. Its subtractive (Ii0) or additive (Ii6) polarity configurations and five‑position ±2×2.5 % off‑circuit taps (18 924–20 916 V) ensure precise voltage matching. Encased in a dead‑front ANSI 70 gray tank rated to 150 kV/30 kV lightning impulse, this transformer provides consistent performance under 60 Hz operation, backed by 20 years of global export expertise and a CESI inspection report for international compliance.
