Product Description

Compact Oil Immersed Power Distribution Transformer
Main Components:
The primary components of this transformer include the 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 cooling and insulation.
2. Complies with IEC standards and holds CE/ISO certificates.
3. Allows easy contact and expansion during load changes, thereby increasing and decreasing the oil temperature efficiently.
4. The Buchholz relay is utilized when a conservator tank is present, indicating 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 in the oil, changing color from blue to pink once it is saturated and can no longer absorb moisture.
6. The oil indicator shows the oil level within the conservator unit, providing essential monitoring.
7. The temperature detector monitors the oil's temperature, disconnecting the transformer from service if the temperature rises too high.
8. The pressure relief device reduces internal pressure to prevent transformer explosion, ensuring safety.
9. The thermal relay acts as an indicator for the winding temperature, providing crucial data for maintenance.
10. Fully galvanized coating ensures no rust, enhancing durability.
11. The bushing connects the internal windings to the external electrical network, facilitating smooth power distribution.
