The rated voltage of the Compact Oil-Filled Electrical Transformer 30 kVA Copper by TSTY ELECTRIC CO., LTD. can be tailored precisely to meet the unique needs of our valued customers.
Meticulously engineered by TSTY ELECTRIC CO., LTD., our fully sealed, oil-immersed power transformer stands out with its exceptional attributes.
This innovative transformer boasts unparalleled advantages: reduced energy loss, minimal operational noise, and superior efficiency. These features collectively deliver significant energy savings and mitigate environmental impact. Unlike conventional oil-immersed transformers, our fully sealed design eliminates the oil conservator, utilizing a corrugated oil tank with an elastic corrugated sheet to automatically adjust and compensate for oil volume changes. This ensures the transformer remains isolated from the air, thereby preventing oil deterioration and insulation aging. Enhanced operational reliability is guaranteed, along with the benefit of maintenance-free operation under normal conditions.
Key Components:
This transformer boasts essential parts including: 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 submerge the windings completely, ensuring optimal cooling and performance.
2. Adheres to IEC standards and holds CE/ISO certifications, guaranteeing reliability and safety.
3. Allows for easy contact and expands under load, facilitating temperature regulation of the oil.
4. The Buchholz relay operates with the conservator tank, signaling issues such as low oil levels or disrupted oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture from the oil and changes color from blue to pink when saturated.
6. The oil indicator provides a clear reading of the oil level within the conservatory unit.
7. The temperature detector continuously monitors oil temperature, disconnecting the transformer to prevent overheating.
8. The pressure relief device alleviates internal pressure, safeguarding the transformer from potential explosions.
9. The thermal relay acts as a temperature indicator specifically for the windings.
10. Fully galvanized coating ensures long-lasting protection against rust.
11. The bushing connects internal windings to the external electrical network efficiently.
