Introducing our top-of-the-line 3-Phase Step Down Electric Power Oil Immersed Distribution Transformer, designed to meet all your high-voltage needs. Available in a wide range of capacities including 50, 80, 100, 150, 160, and 200 kVA, as well as 1, 2, 2.5, 3, 4, and 5 MVA, this versatile transformer operates efficiently at 11kV, 10kV, 0.4kV, and 400V voltages. Engineered for robustness and reliability, this oil-filled transformer ensures superior energy distribution for industrial and commercial applications.
The rated voltage can be expertly customized to meet the specific requirements of our esteemed customers.
The state-of-the-art, fully sealed oil-immersed power transformer engineered by TSTY ELECTRIC CO., LTD. boasts remarkable features and benefits.
Key advantages include low loss, minimal noise, and superior efficiency. This transformative device not only delivers exceptional energy-saving capabilities, significantly reducing pollution, but also offers a host of improvements over traditional oil-immersed transformers. Fully sealed to eliminate the need for an oil conservator, the innovative corrugated oil tank adjusts and compensates for oil volume changes automatically. This design effectively isolates the transformer from air exposure, thereby preventing oil deterioration and insulation aging, enhancing operational reliability, and virtually eliminating maintenance during normal operations.
Main Components:
The major components of this transformer include an Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to immerse the windings, ensuring optimal insulation and cooling.
2. Compliant with IEC standards and certified by CE and ISO.
3. Facilitates easy contact and expansion during loading, allowing the oil temperature to increase and decrease efficiently.
4. The Buchholz relay is essential when a conservator tank is used. It signals issues such as oil loss, low oil levels, and improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil. It changes color from blue to pink when it can no longer absorb moisture.
6. The oil indicator shows the oil level within the conservator unit, ensuring proper monitoring.
7. The temperature detector monitors oil temperature. If it rises beyond a set threshold, the transformer will automatically disconnect from service.
8. The pressure relief device mitigates pressure build-up within the transformer, preventing potential explosions.
9. The thermal relay acts as an indicator for the winding temperature, ensuring safe operation.
10. Completely galvanized coating to prevent rust and ensure longevity.
11. The bushing connects the internal windings of the transformer to the external electrical network, ensuring seamless energy transfer.
