Oil Filled Transformer Product Features
The core is made of high-quality, high-performance silicon steel sheets, with low no-load loss.
The high-voltage winding adopts a layered structure, with high mechanical strength, balanced distribution, and strong short-circuit resistance.
The overall structure is fully sealed, and the vacuum oil filling process is adopted to ensure that the transformer oil is isolated from the outside air, prevent oil aging, and improve the reliability of transformer operation.
The product is equipped with a pressure relief valve, signal thermometer, gas relay, etc. to ensure the safe operation of the transformer.
The corrugated oil tank is used, which is simple to process, has high mechanical strength, good welding effect, no leakage, and good heat dissipation capacity.
It has beautiful appearance and small size, and is widely used in urban and rural power grids.
Customization Optional
800kVA Oil Filled Transformer
GNEE's 800kVA oil-immersed transformers can provide a variety of optional specifications according to customer needs to meet different application scenarios and technical requirements. The primary and secondary voltages can be customized according to the power grid standards of different countries and regions, such as 6.6kV/400V, 10kV/415V, 11kV/433V, 20kV/400V, etc. ONAN (natural oil circulation/natural air cooling) or ONAF (natural oil circulation/forced air cooling) cooling methods are provided to adapt to different load conditions. Low-loss models can be customized according to IEC, GB, ANSI, DOE, and other standards to improve energy efficiency and are suitable for green energy-saving projects.
In addition, moisture-proof, anti-corrosion, and anti-salt spray coatings can also be selected to adapt to high humidity, coastal areas, or highly polluted industrial areas. These optional specifications ensure that GNEE's 800kVA oil-immersed transformers can meet the needs of various complex working conditions and different industries, providing higher reliability and operating efficiency.
