220kV Power Transformer with Amorphous Alloy Core (50000kVA-100000kVA) is a high-efficiency device for medium and large power systems. Adopting advanced amorphous alloy core, it features low no-load loss and excellent magnetic conductivity, suitable for three-phase AC power transmission and distribution.
Operating stably at 50Hz/60Hz, its electrical performance fully complies with GB7251 and IEC60439 standards. The precision-manufactured core ensures strong mechanical strength, resisting vibration and impact during use.
Widely used in power generation, industrial and mining enterprises and housing construction, it fits three-phase three/four/five-wire systems, with low noise and long service life. Its reliability is verified in over 50 countries including Kuwait, UAE, Saudi Arabia and South Africa, ideal for global high-voltage projects.
