Available in both oil-immersed and dry type configurations, these transformers are designed to meet diverse voltage requirements of 6kv, 11kv, 33kv, and 35kv. Trust in TSTY ELECTRIC CO., LTD. to deliver superior quality and performance in every product.
The rated voltage can be customized to meet the precise requirements of our customers.
The innovative fully sealed oil-immersed power transformer developed by TSTY ELECTRIC CO., LTD. boasts an impressive array of features.
With the advantages of low loss, minimal noise, and exceptional efficiency , this transformer excels in energy conservation and pollution reduction. Unlike ordinary oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The fluctuation in oil volume is seamlessly managed by the elasticity of the corrugated sheet within the corrugated oil tank. This ensures the transformer remains isolated from air, thereby preventing and delaying oil deterioration and insulation aging. This innovation enhances operational reliability and allows for maintenance-free operation under normal conditions.
Main Components:
The principal parts of this state-of-the-art 2500kVA Power Transformer comprise the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank houses and immerses the windings to ensure optimal performance and cooling.
2. Fully compliant with IEC standards, equipped with CE and ISO certifications for ultimate reliability.
3. Designed for seamless connectivity and efficient thermal management, allowing the oil temperature to rise and fall effectively during load variations.
4. The Buchholz relay is essential when a conservator tank is in use, providing alerts for issues such as low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel, which absorbs moisture from the oil and changes color from blue to pink when it can no longer absorb moisture effectively.
6. The oil indicator accurately displays the oil level within the conservatory unit, ensuring maintenance and operational efficiency.
7. A highly sensitive Temperature Detector monitors the oil temperature, automatically disconnecting the transformer from service if the temperature exceeds safe levels.
8. The Pressure Relief Device effectively reduces internal pressure to prevent transformer explosions, ensuring operational safety.
9. The Thermal Relay serves as an indicator for the winding's temperature, ensuring its protection and longevity.
10. Full galvanized coating ensures complete protection against rust, enhancing the transformer’s durability.
11. The bushing facilitates the connection of the transformer's internal windings to an external electrical network, ensuring seamless electrical integration.
