Product Description
Shiyou Electric oil distribution transformer includes hermetically sealed, amorphous alloy, conservator type and on-load tap changer type, which is usually pole mounted or installed in distribution station for daily lighting and factory power whose LV output up to 0.4kV.
Our distribution transformer rating is up to 25000kVA, and primary voltage up to 110kV. The corrugated tanks as thermal expansion and contraction component enable the transformer oil completely isolated with the atmosphere. Oil distribution transformer with primary voltage range of 6,10,10.5,11,20,22,24,33, 35,38.5,66,110,121kV can be manufactured according to customer requirements.
Main Characteristics:
1. Adopting patented technology and software design, with excellent performance.
2. The iron core is made of high-quality cold-rolled grain oriented silicon steel sheets and produced using step overlap technology.
3. The winding adopts high-strength enameled wire, paper insulated wire or copper strip, with uniform distribution of current turns, reasonable insulation structure, and strong short-circuit resistance.
4. The low-voltage coil is wound with copper wire or copper foil, while the high-voltage coil is cast with epoxy resin in a vacuum state, which is oil-free, maintenance free, has small partial discharge, and high reliability
5. The active part adopts a coreless suspension structure. The gasket is made of high-quality acrylic rubber, which can suppress aging caused by sunlight and heat.
Applications:
1. Building Infrastructure and Industrial: Airports, hospitals, factories, shopping malls, hotels, commercial and residential towers.
2. Utility: Generation, transmission, distribution substations, water and waste water treatment plants.
3. Oil and Gas: Oil and gas plants, petrochemical plants and refineries.
Service environment:
1. Ambient temperature: Maximum +40ºC, Minimum -40ºC.Parameters can also be customized according to the customer's environment, such as long-term stable operation in a 55 ºC desert environment
2. Altitude: less than 1000 meters.
3. Seismic level: less than 3m/s2 at horizontal direction and less than 1.5m/s2 at vertical direction.
4. Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
No. | Product Feature | Advantages |
1. | No Partial Discharge | Actual measured partial discharge is less than 50pC, lower than the background noise. |
2. | High Efficiency and Low Loss: | Innovative core and coil design, along with leakage magnetic flux control technology, effectively reduces additional and stray losses. |
3. | Low Noise | Actual measured noise is below 60dB, significantly better than the national standard noise levels. |
4. | Intelligent Design | Meets the operational requirements of intelligent substations. |
5. | Maintenance-Free Design | Comprehensive design includes air self-cooling methods, fiberglass dry-type bushings, and metal corrugated internal oil-type conservators, free of routine on-site maintenance, making it suitable for unattended substations. |
6. | Compact Structure Design | Adopt the industrial advanced 220kV end inlet method, resulting in a compact overall structure, facilitating easier transportation and on-site installation. |
7. | Strong Short Circuit Resistance | Utilizes foreign short-circuit mechanical force verification procedures and ensures all assembly stages of the transformer body meet design requirements. |
8. | Over 15-Year's Design Life | Unique high-temperature-resistant hybrid insulation system based on temperature field simulation analysis, ensuring all transformer components have the same design life as the transformer itself. |
9. | Passes All Routine and Type Tests at Once | The transformer's overall performance reaches advanced domestic levels. |
