Single Phase Pad Mounted Transformer Standard Features
WINLEY’s Single Phase Pad Mounted Transformer (Compartmental-Type II) is a reliable power distribution solution designed for radial feed systems. With 75 kVA capacity and 25 kV primary voltage class, this transformer connects to a 3-phase grid while delivering single-phase power at 120/240V (L-N-L) secondary voltage. Built to ANSI/IEEE standards, it features additive polarity and a delta primary/dual winding single phase secondary configuration, ensuring compatibility with diverse electrical setups.
Single Phase Pad Mounted Transformer Drawing
Engineered for durability, the transformer includes a weather-resistant dead front enclosure (ANSI Type II arrangement) and Class E insulation (120°C rating), suitable for self-cooled (KNAN) operation in 60 Hz systems. Its 5-position hot stick operable tap changer (2.5% steps) allows field voltage adjustment, while 150 kV primary BIL and 30 kV secondary BIL ratings ensure robust surge protection. With 1.0–4.5% typical impedance and low 65°C temperature rise, this compact transformer offers efficient, stable performance for urban and suburban applications, backed by UL/cUL certification for safety and compliance.
