The WINLEY 25 kVA Single Phase Pole Mounted Transformer provides a reliable, high-performance solution for overhead utility networks and rural power distribution. Engineered to convert 24940GrdY/14400V or 12470GrdY/7200V primary voltages down to a 120/240V secondary output, this oil-immersed (ONAN) unit fully complies with Canadian standards CSA C2.2-06 and CSA 802, making it an ideal choice for standard grid integrations. Its compact pole-mounted configuration allows for highly efficient installation and immediate deployment in regional overhead systems.
Built with an integrated dual-voltage switch and a 5-position off-circuit tap changer (±2 × 2.5%), this transformer delivers exceptional operational versatility. This feature enables utilities to standardize a single transformer type across diverse multi-voltage networks, significantly reducing procurement inventory overhead while ensuring precise local voltage regulation. Backed by a 125kV BIL high-voltage bushing and certified low-loss performance, it directly secures long-term cost savings and operational stability for contractors and utility operators.
