Introducing the 12500kVA 33/11kv Oil Immersed Power Distribution Transformer from TSTY ELECTRIC CO., LTD. Engineered for superior performance and reliability, this state-of-the-art transformer is designed to efficiently handle your power distribution needs with unmatched expertise. Whether for industrial or commercial applications, trust in the durability and precision of our 12500kVA Copper Electrical Power Transformer to deliver consistent and optimal power distribution.
The rated voltage is highly customizable to meet specific customer requirements, ensuring optimal performance and flexibility.
Our state-of-the-art fully sealed oil-immersed power transformer, a flagship product of TSTY ELECTRIC CO., LTD., boasts
exceptional features such as low energy loss, minimal noise, and superior efficiency. This innovative design not only delivers excellent energy-saving benefits and significantly reduces pollution, but also offers a myriad of advancements over traditional oil-immersed transformers. By eliminating the need for an oil conservator, the fully sealed transformer autonomously adjusts and compensates for oil volume changes via the elasticity of the corrugated oil tank's sheets. This design ensures the transformer remains isolated from external air, thereby preventing oil deterioration and insulation aging. It enhances operational reliability, minimizes maintenance, and guarantees seamless performance during normal operations.
Main Components:
The primary parts of the 12500kVA Copper Electrical Power 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 immerses the windings in oil to provide essential cooling and insulation.
2. Complies with IEC standards and holds CE/ISO certifications.
3. Allows easy contact and expansion during loading, so the oil temperature can increase and decrease smoothly.
4. The Buchholz relay, used with a conservator tank, detects faults like oil loss and improper oil flow, ensuring efficient operation and safety.
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.
7. The temperature detector monitors oil temperature. If the oil overheats, the transformer is automatically disconnected to prevent damage.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay serves as a temperature indicator for the windings.
10. Fully galvanized coating ensures no rust.
11. The bushing connects the internal windings to the external electrical network seamlessly.
