Boasting an exceptionally wide load capacity range—spanning from 100 kVA to 10,000 kVA—this transformer is perfectly suited to meet massive load demands, such as those found in the main power distribution systems of large-scale factories and major substations. It seamlessly handles the high-capacity requirements that dry-type transformers are unable to accommodate.
Offering a lower cost point compared to dry-type transformers, this solution delivers significant savings on equipment costs for large-scale power distribution projects. There is no need to incur the high expense of purchasing dry-type units; oil-immersed transformers suffice, thereby substantially reducing overall project costs.
Featuring robust weather resistance, the unit can be installed directly outdoors without fear of exposure to sun or rain. Its corrugated tank design incorporates a sealed structure that prevents oil leakage and protects against contamination, making Oil-immersed Distribution Transformer perfectly adapted to withstand harsh outdoor environments and eliminating the need to construct a dedicated indoor distribution room.
Utilizing a high-quality silicon steel core, the transformer exhibits extremely low power loss. Over the course of long-term operation, this translates into substantial savings on electricity bills, delivering significant energy-saving benefits—specifically, a 15% reduction in power loss compared to older-generation oil-immersed transformers.
Characterized by a low failure rate, Oil-immersed Distribution Transformer benefits from highly mature technology and stable operational performance. As a proven solution that has been utilized within the power distribution industry for decades, it offers convenient maintenance and is ideally suited for large-scale outdoor power distribution applications.

1.Question: What are the differences between oil-immersed distribution transformers and dry-type transformers?
Answer: The capacity of oil-immersed transformers can reach 100kva to 10,000kva, which can meet the needs of extremely large loads. However, the capacity of dry-type transformers is limited. At the same time, oil-immersed transformers are cheaper than dry-type transformers and can be directly placed outdoors without the need for an indoor distribution room, making them more suitable for large outdoor high-capacity distribution scenarios.
2. Question: Can this product be used directly outdoors?
Answer: We have adopted a corrugated sealed oil tank design, which has strong sealing performance. It can effectively prevent oil leakage and pollution. Combined with the outdoor-specific protective structure, it can prevent moisture, resist sunlight, rain and other elements. No additional protective facilities are required. It perfectly suits the harsh outdoor environment and does not need to build an indoor power distribution room separately.
3. Question: Can the capacity and voltage of the oil-immersed transformer be customized?
Answer: Oil-immersed Distribution Transformer has a rated capacity ranging from 100KVA to 10,000KVA, and a rated voltage covering high voltage 10kV/35kV and low voltage 0.4kV. At the same time, the impedance voltage, voltage regulation method, and winding material can all be customized. According to the outdoor power distribution requirements of different scenarios such as large factories and outdoor substations, we can tailor specific equipment to precisely meet the large-capacity outdoor power distribution needs.
4. Question: Where does the low-loss advantage of this product specifically lie?
Answer: We use high-quality silicon steel sheet cores, which have a loss rate 15% lower than that of the old oil-immersed transformers. The energy-saving effect is remarkable. Under long-term operation, it can significantly reduce electrical energy loss. The specific amount of electricity saved depends on the actual capacity and operating duration. The larger the capacity and the longer the operation time, the more electricity is saved, which can help large power distribution projects save long-term operation and maintenance costs.
