Power Transformers
A power transformer is a static machine used for transforming power from one circuit to another without changing the frequency. As there is no rotating or moving parts, a transformer is classified as a static device. Transformer operates on an AC supply. Backed by decades of experience and expertise in Power Transformers in Nepal, ABC has developed a comprehensive range of Power and Extra High Voltage Transformers. These products are engineered to perfection and are developed using qualitative raw material and advanced manufacturing facilities and techniques.
