IEC60076 High IP Rating 1000KVA Single Phase Pole Mounted Transformer 11KV/230V for Tropical / Humid Climate Sites Manufacture

The Single Phase Pole Mounted Cylindrical Transformer is a high-reliability overhead distribution transformer designed for rural electrification, utility grids, and industrial auxiliary power supply systems. Engineered in compliance with IEC60076 standards, it provides stable voltage conversion from medium voltage (e.g., 11kV, 13.2kV, 22kV, 33kV) down to low voltage (230V / 240V / 110V) for end-user distribution.

This transformer adopts a sealed cylindrical tank design with high IP protection rating, ensuring superior resistance against moisture, corrosion, salt fog, dust, and extreme tropical climates. It is widely used in Southeast Asia, Africa, Latin America, coastal regions, and high-humidity environments where reliability and low maintenance are critical.

Our factory provides fully customized solutions including voltage rating, insulation class, bushing type, surge protection, and mounting structure.
