220kV oil immersed power transformer
220kV oil immersed power transformer
Oil immersed power transformers meet the requirements of national standards GB/T1094 and GB/T6451. The iron core is manufactured using cold-rolled grain oriented high magnetic conductivity silicon steel sheet technology, the coil is wound with high-strength copper wire, and the oil tank is a bell shaped structure. Depending on the installation environment, high-quality acrylic or chloroprene rubber seals are used, which can be widely used in power plants, power stations, industrial and mining enterprises, substations and other substation systems.
