110kV/132kv oil-immersed Power Transformer

Overview

In response to the global growth in electricity demand, 110kV /132kv three-phase oil-immersed transformers are widely used in national power grids, industrial and mining enterprises, regional substations, power plant step-up stations, and public utility systems.
These transformers are mainly designed for voltage step-up or step-down applications, ensuring efficient energy transmission and reliable power distribution.

With a maximum capacity of up to 200 MVA, our 110kV/132kv  transformers have been proven in high-reliability operation across more than 50 countries and regions, including Tanzania, Zimbabwe, Ghana, South Africa, Kenya, Zambia, Sudan, Libya, Congo, the UAE, Saudi Arabia, Iraq, Syria, and Bangladesh.
