Unlock the power of efficiency with the Aluminium 11/0.4kV Electrical Distribution Transformer from TSTY ELECTRIC CO., LTD. Available in capacities ranging from 50 kVA to 5 MVA, this three-phase, oil-immersed transformer operates at voltages of 11kV, 10kV, 0.4kV, and 400V. Designed for robust performance, it ensures reliable, step-down electric power distribution, meeting diverse industrial and commercial needs with unparalleled precision and longevity.
The rated voltage is fully customizable to meet the precise requirements of our esteemed customers.
The state-of-the-art fully sealed oil-immersed power transformer from TSTY ELECTRIC CO., LTD. boasts the
advantages of exceptionally low loss, minimal noise, and unparalleled efficiency , delivering outstanding energy savings while significantly reducing environmental pollution. Unlike traditional oil-immersed transformers, this innovative fully sealed version eliminates the need for an oil conservator. The transformer adapts automatically to changes in oil volume through the elasticity of the corrugated sheet in the oil tank, ensuring complete isolation from air. This design prevents oil deterioration and insulation aging, thereby enhancing operational reliability and extending the maintenance-free period.
Main Components:
The primary components of this exceptional Aluminium 11/0.4kV Electrical Distribution Transformer include the following: 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 efficient cooling and insulation.
2. Complies with IEC standards and is certified with CE and ISO certifications.
3. Facilitates easy contact and expansion during loading, thereby allowing the oil temperature to rise and fall effectively.
4. The Buchholz relay, essential when a conservator tank is used, detects faults such as oil loss and improper oil flow between the tank and transformer.
5. The Breather Unit contains silica gel that absorbs moisture from the oil. The gel changes color from blue to pink when it can no longer absorb moisture.
6. The oil indicator accurately displays the oil level within the conservator unit.
7. The temperature detector continuously monitors the oil temperature. If the temperature rises beyond a certain threshold, the transformer will automatically disconnect from the service.
8. The pressure relief device reduces internal pressure to prevent transformer explosions.
9. The thermal relay serves as an indicator for the winding temperature.
10. Features full galvanized coating for superior rust resistance.
11. The bushing connects the internal windings of the transformer with the external electrical network.
