Experience unparalleled power efficiency with our 50, 80, 100, 150, 160, and 200 kVA, as well as 1, 2, 2.5, 3, 4, and 5 MVA rated 11kV, 10kV, 0.4kV, and 400V voltage 3-phase step-down electric power oil-immersed distribution transformers. Engineered for high performance and utmost reliability, these transformers are perfect for your electrical power distribution needs.
The rated voltage can be customized to meet customers' specifications and requirements.
The innovative fully sealed oil-immersed power transformer, meticulously developed by TSTY ELECTRIC CO., LTD., boasts unparalleled qualities.
This state-of-the-art transformer offers the remarkable benefits of low loss, minimal noise, and exceptional efficiency. Its design not only ensures a superior energy-saving effect and reduces environmental pollution but also stands out compared to conventional oil-immersed transformers. The fully sealed construction eliminates the need for an oil conservator. Instead, the oil volume adjusts automatically through the corrugated oil tank's flexible sheet. This isolation from the air prevents oil deterioration and insulation aging, significantly enhancing operational reliability and eliminating the requirement for regular maintenance during normal operation.
Key Components:
This state-of-the-art transformer comprises essential parts including: 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 performance and cooling.
2. Adheres to IEC standards and proudly carries CE/ISO certifications.
3. Facilitates easy contact and expansion during load variations, allowing for efficient oil temperature regulation.
4. The Buchholz relay is critical when a conservator tank is present, signaling issues like oil loss, or improper oil flow between the tank and transformer.
5. The Breather Unit, filled with silica gel, absorbs oil moisture. Its color changes from blue to pink when it needs replacement.
6. The oil indicator accurately shows the oil level within the conservatory unit.
7. The temperature detector monitors the oil temperature and automatically disconnects the transformer if it exceeds safe levels.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay acts as a temperature indicator for the windings.
10. Features a fully galvanized coating to ensure long-lasting, rust-free protection.
11. The bushing connects the internal windings of the transformer to the external electrical network efficiently.
