GNEE Steel Oil Type Transformers
The oil-immersed distribution transformer has significant energy saving, uniform magnetic circuit, low no-load loss, low noise temperature rise, maintenance-free and high efficiency. The distribution transformer has significant energy saving effect and uses new core materials. The magnetic circuit is evenly distributed, which greatly reduces the no-load excitation current and no-load loss. Because the iron core is a fully tilted three-slit structure. Reliable operation. small volume. Light weight. Low noise, good craftsmanship and good heat dissipation. Low temperature rise, no hanging core structure, no pollution to the environment, maintenance-free and high efficiency. It can be used for power supply and lighting in residential areas, commercial streets, industrial and mining enterprises, rural areas, etc.
