20/22kV three-phase oil-immersed transformer
15-22kV oil‑immersed transformers are widely used in medium‑voltage power distribution networks, both in China and internationally. In China, voltage classes such as 20kV are gaining popularity in industrial parks and urban distribution grids, particularly in regions where higher power density is required without stepping up to 35kV. These transformers step down primary voltages of 15kV, 20kV, or 22kV to secondary levels like 0.4kV, 6kV, or 10kV, depending on local standards.
H59-H61 pole-mounted transformer
The H61 pole‑mounted distribution transformer is a three‑phase, oil‑immersed unit specifically designed for overhead distribution networks, particularly in rural and peri‑urban areas where reliable and low‑maintenance power supply is critical. This transformer type is widely specified by electricity utilities in French‑speaking West African countries (such as Côte d'Ivoire, Cameroon, Senegal, etc.), where it serves as a standard solution for medium‑voltage to low‑voltage (MV/LV) power conversion. Manufactured in strict compliance with IEC 60076, as well as NF C52‑112‑1, HD 428.1 and HN 52‑S‑20 standards, the H61 transformer guarantees safe, efficient and long‑lasting operation even under harsh environmental conditions.
