Product introduction
This is a 20MVA (20000kVA) three phase oil immersed on load tap changer power transformer manufactured by Jiangsu Yawei Electric Group Co., Ltd., designed for overseas substation projects in Sudan.
The transformer adopts SZ series on‑load tap‑changer (OLTC), with HV tap range of 33±9×1.67%, which can adjust output voltage continuously under full load condition to stabilize the 11 kV secondary voltage against grid fluctuation. Its vector group is Dyn11, short‑circuit impedance is 8%, suitable for 50 Hz power system.
Designed and manufactured in accordance with IEC and international power standards, this transformer features low loss, low noise, strong short‑circuit withstand capability and reliable sealing performance. It is equipped with radiators, conservator, oil‑level indicator, protection devices and rail mounting base for convenient transportation and on‑site installation. It is widely applied in main substations for power transmission & distribution in Africa and other overseas markets.
