Available in a range of capacities including 50, 80, 100, 150, 160, and 200 kVA, and extending up to 1, 2, 2.5, 3, 4, and 5 MVA, this transformer operates efficiently with voltage ratings of 11kV, 10kV, 0.4kV, and 400V. Experience seamless and reliable power distribution with our state-of-the-art, oil-immersed technology tailored to your unique requirements.
The rated voltage can be tailored precisely to meet your specific needs and requirements.
The fully sealed oil-immersed power transformer, masterfully engineered by TSTY ELECTRIC CO., LTD., boasts the
advantage of impressively low loss, minimal noise production, and exceptional efficiency , which culminates in outstanding energy-saving performance while also mitigating environmental pollution. In contrast to conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. Instead, oil volume fluctuations are seamlessly adjusted and compensated by the corrugated oil tank's resilient sheet. This innovative design isolates the transformer from the air, thereby preventing oil deterioration and insulation aging, significantly enhancing operational reliability, and ensuring maintenance-free operation under normal conditions.
Main Components:
The primary components of the 3-Phase Oil-Immersed Step Down Transformer include: 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, ensuring efficient cooling and insulation.
2. Fully compliant with IEC standards and endorsed by CE/ISO certifications.
3. Designed for optimal contact and expansion under load, allowing the oil temperature to increase and decrease as needed.
4. The Buchholz relay is essential when using a conservator tank. It detects errors such as oil loss or improper oil flow between the tank and the transformer.
5. The Breather Unit contains silica gel that absorbs moisture from the oil. It changes from blue to pink when saturated.
6. The oil indicator shows the oil level within the conservator unit.
7. The temperature detector monitors 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 indicates the temperature of the windings.
10. Full galvanized coating ensures no rust formation.
11. The bushing connects the internal windings of the transformer to the external electrical network.
