Product Description
Medium Voltage Three Phase Oil Immersed Power Transformer /Distribution Transformer
Distribution transformer oil-immersed with power rating from 25 to 2500 kVA and Voltage 6-36/0,4 (0.23)kV. In 50/60 Hz power transmission and distribution system for power supply and lighting in industrial and agricultural field. Distribution transformers are produced with nominal Voltage in primary winding 6 up to 36 kV. Nominal Voltage in secondary winding is 0,4 or 0,23 kV. Scheme and connection group of windings U/Un-0 or D/Un-11, etc.
On the customer demand it is possible to make transformers with different connection of the Voltage s and other construction solution. Regulating the Voltage is made as a result of moving the switch, by the transformer detached from the net both high (HV) and low (LV) Voltages.
The Voltage is being regulated on the side of HV for ±2x2,5% value from nominal value. Exterior introductions HV and LV are removable and passers-by are made from china insulators. At great current 1000 A and more on the hard core current are contact clamps screwed properly with the spatula which connecting the track or the cable attachment assures. The expandability of oil assures appropriate works of the transformer at different weather conditions and fluctuations of the temperature. The dehumidifier is installed to provide dry air in transformer. For measuring the temperature of upper layers of oil on the casing a thermometer is installed. Transformers with power rating from 400 to 2500 kVA are occupied with wells to install in base.
Features
Energy saved :Compared with old type S7, no-load loss decreases 10.25% averagely and on-load current decreases 37.9%, which means 18.39% operation cost is reduced.
Long-term reliable service life:Fully enclosed transformer tank and rim shall be bolted together or welded firmly. Isolation between oil and air keeps insulation away from moisture, which lowers insulation aging and improves service life.
Free from untanking:Free from untanking before operation, so its cost is saved.
Free from maintenance
Low noise:Impacted structure in design, new material and new technology adopted and low noise.
Small size and artistic appearance:Owing to the corrugated plate used for radiation, oil volume is changed by adjustment and compensation through expansion and shrinkage of corrugated plate when the temperature of oil is changed. Corrugated tank is small size in good looking.

H61 and H59 are high-quality copper alloys with excellent electrical conductivity and corrosion resistance—core advantages for reliable transformer operation. They ensure low energy loss during power transmission (no-load loss reduced by 15%-20% vs. ordinary materials) and enhance the transformer’s durability, withstanding harsh outdoor conditions (e.g., humidity, temperature fluctuations) for a 20-year design service life. The alloys also improve mechanical strength, preventing deformation under long-term load, making the transformer suitable for continuous industrial and civil power supply.

How does the oil in oil-immersed power transformers clean itself?The self-cleaning mechanism of transformer oil is typically achieved through the following methods: Oil Purifier FiltrationOil purifiers are common purification devices in transformers, filled with adsorbents such as silica gel or activated alumina. During transformer operation, convection caused by oil temperature changes drives the oil to flow downward through the purifier. Moisture, acidic substances, and oxidation byproducts in the oil are absorbed by the adsorbent, thereby maintaining oil c12/06/2025 -
Avoid H59 Transformer Failure with Proper Inspection & CareMeasures to Prevent H59 Oil Immersed Power Distribution Transformer from Burning OutIn power systems, H59 Oil Immersed Power Distribution Transformer play an extremely critical role. Once burned out, they can cause widespread power outages, directly or indirectly affecting the production and daily lives of a large number of electricity users. Based on the analysis of multiple transformer burnout incidents, the author believes that a considerable number of such failures could have been avoided or12/06/2025 -
Top Causes of H59 Distribution Transformer Failure1. OverloadFirst, with the improvement of people's living standards, electricity consumption has generally increased rapidly. The original H59 distribution transformers have small capacity—“a small horse pulling a big cart”—and cannot meet user demands, causing the transformers to operate under overload conditions. Second, seasonal variations and extreme weather conditions lead to peak electricity demand, further causing H59 distribution transformers to run overloaded.Due to long-term overload o12/06/2025 -
How to Select H61 Distribution Transformers？H61 Distribution Transformer Selection includes the selection of transformer capacity, model type, and installation location.1.Selection of H61 Distribution Transformer CapacityThe capacity of H61 distribution transformers should be selected based on the current conditions and development trends of the area. If the capacity is too large, it results in the “large horse pulling a small cart” phenomenon—low transformer utilization and increased no-load losses. If the capacity is too small, the tran12/06/2025 -
