Oil immersed power transformers meet the requirements of national standards GB/T1094.andGB/T6451.The iron core is manufactured using the cold rolled grain oriented high magnetic siliconsteel sheet process, and the wire is wound with high-strength copper wires. The oil tank is a bellshaped structure, and according to different installation environments, high-quality acrylic or chloro-

prene rubber seals are used. lt can be widely used in power plants, power stations, industrial andmining enterprises, substations and other substation systems.
