Experience Unmatched Performance with the 12500kVA 33/11kV Oil Immersed Power Distribution Transformer. Engineered for optimum efficiency and reliability, this transformer is the epitome of high-quality craftsmanship and advanced technology. Ideal for a myriad of industrial and commercial power distribution applications, it ensures seamless energy flow and robust operational integrity.
The rated voltage can be customized according to customers' specific requirements, ensuring versatile application and performance.
The fully sealed oil-immersed power transformer by TSTY ELECTRIC CO., LTD. boasts a stellar design that
offers the advantages of low loss, minimal noise, and exceptional efficiency . This innovative design not only achieves remarkable energy-saving results but also minimizes environmental pollution. Unlike traditional oil-immersed transformers, this fully sealed model eliminates the need for an oil conservator. The fluctuating oil volume is seamlessly adjusted and compensated by the corrugated sheet's elasticity in the corrugated oil tank. This isolation from air significantly prevents oil deterioration and insulation aging, thereby enhancing operational reliability and reducing the need for maintenance during normal operation.
Main Components:
The essential components of this transformer include: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Level Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to immerse the windings for optimal insulation and cooling.
2. Complies with IEC standards and certified with CE/ISO certifications.
3. Facilitates easy contact and expansion during loading, allowing the oil temperature to increase and decrease efficiently.
4. The Buchholz relay is essential with a conservator tank, detecting anomalies such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel to absorb moisture. It changes color from blue to pink when it can no longer absorb moisture.
6. The oil level indicator shows the level of oil in the conservator unit.
7. The temperature detector monitors the oil temperature, disconnecting 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. Fully galvanized coating ensures no rust formation.
11. The bushing allows connection of internal windings to the external electrical network.
