110kV oil‑immersed power transformer is manufactured in strict accordance with IEC 60076, GB 1094 and other international standards. It features low loss, low noise, high mechanical strength, strong short‑circuit withstand capability, reliable sealing and low maintenance. It is widely used in distribution substations, industrial and mining enterprises, urban power grids and rural power transmission projects.
This series transformer adopts high‑quality core materials, optimized winding structure and robust oil tank design, with stable performance and long service life. It supports multiple cooling methods, insulating medium options and on‑load tap changers, and can be customized in capacity, voltage, vector group and technical parameters. Equipped with complete safety protection devices, it provides stable and safe operation for various high‑voltage power supply scenarios.
