1500 kva oil filled transformer
Oil immersed power transformer,based on know-how accumulated over decade years in oil immersed distribution transformer field, GNEE oil-immersed transformers have been supplied to various industries including semiconductor, steel work, and petrochemical. Further, as an outstanding and comprehensive oil immersed distribution transformer solution provider, we respond to the oil immersed power transformer demanding requirements of our customers by developing and manufacturing both eco-friendly pole mounted distribution transformer and high-efficiency oil immersed power transformer. Both oil immersed distribution transformer and pole mounted distribution transformer are designed for power centres,substations and network, also for pad mounted oil immersed power transformer, used in public distribution system, commercial building and industrial complexes.

Advantages of a three-phase oil-immersed transformer

-The core of silicon steel is made of 0.18 ~ 0.3mm orientation silicon steel sheet stacked by punching and shearing, which has good stability.

-The coil is made of pure copper. The acetal enamelled wire is used for high voltage and oxygen-free copper conductor or copper foil for low voltage to improve the short-circuit resistance.

-The Dyn11 connection symbol is used to avoid the influence of higher harmonics. It provides high resistance against uncompensated load and improves the quality of power supply.

-Vacuum oiling is adopted by the transformer to remove bubbles in the core and ensure stable insulating property.
