Available in power ratings of 50, 80, 100, 150, 160, and 200 kVA, as well as 1, 2, 2.5, 3, 4, and 5 MVA, this 3-phase transformer is adept at stepping down electric power from 11kV or 10kV to a reliable 0.4kV (400V). Engineered for peak performance and durability, our transformers ensure seamless electric power distribution for diverse industrial and commercial applications.
The rated voltage can be precisely tailored to meet the unique specifications required by our esteemed customers.
The state-of-the-art, fully sealed oil-immersed power transformer, engineered by TSTY ELECTRIC CO., LTD., boasts remarkable features:
Exceptional benefits include low loss, minimal noise, and superior efficiency, resulting in significant energy savings and reduced environmental impact. Unlike ordinary oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The transformer adapts to oil volume changes automatically through the corrugated sheet's elasticity within the oil tank. This innovative design isolates the transformer from air, thereby preventing oil degradation and insulation aging. The result is enhanced operational reliability and a maintenance-free experience under normal conditions.
Main Components:
The primary components of this superior transformer include the 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 efficient cooling and insulation.
2. Compliant with IEC standards and proudly bearing CE/ISO certifications.
3. Facilitates effortless contact and expansion during load variations, enabling the oil temperature to increase and decrease as needed.
4. The Buchholz relay, essential when a conservator tank is utilized, detects issues like oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit, filled with silica gel, absorbs moisture within the oil. As it saturates, the gel changes from blue to pink, indicating its inability to absorb further moisture.
6. The oil indicator precisely shows the oil level within the conservatory unit.
7. The temperature detector continuously monitors the oil's temperature. Should it rise beyond a certain threshold, the transformer will be safely disconnected from service.
8. The pressure relief device effectively reduces internal pressure to prevent transformer explosions.
9. The thermal relay serves as a reliable indicator of the winding's temperature.
10. Fully galvanized coating ensures no rust, providing excellent durability.
11. The bushing connects the internal windings of the transformer to an external electrical network with precision and reliability.
