The rated voltage can be precisely tailored to meet the specific requirements of our esteemed customers.
The state-of-the-art fully sealed oil-immersed power transformer crafted by TSTY ELECTRIC CO., LTD. boasts
exceptional benefits such as minimal energy loss, whisper-quiet operation, and superior efficiency, delivering outstanding energy-saving performance while significantly reducing environmental pollution. Unlike conventional oil-immersed transformers, this fully sealed model eliminates the need for an oil conservator. The oil volume adjustment is seamlessly managed by the elasticity of the corrugated sheet in the corrugated oil tank. This intelligent design ensures the transformer remains isolated from air, thereby preventing oil deterioration and insulation aging. This results in enhanced operational reliability and eliminates the need for maintenance during standard operation.
Main Components:
The key components of our Oil-Immersed Power Distribution Transformer 200 kVA Copper 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 house and immerse the windings in insulating oil.
2. Our transformers comply with IEC standards and come with CE/ISO certifications, ensuring unparalleled quality and safety.
3. Easy accessibility and expansion during loading facilitate the temperature regulation of the oil.
4. The Buchholz relay, used in systems with a conservator tank, detects errors such as oil loss or improper oil flow between the tank and transformer.
5. The Breather Unit, equipped with silica gel, absorbs moisture within the oil. The silica gel changes color from blue to pink once it can no longer absorb moisture.
6. The oil indicator measures the oil level within the conservatory unit.
7. The temperature detector monitors the oil's temperature, disconnecting the transformer from service if the temperature exceeds safe limits.
8. The pressure relief device is designed to reduce internal pressure, preventing potential explosions.
9. The thermal relay acts as a critical indicator by measuring the temperature of the windings.
10. Full galvanized coating ensures the transformer remains rust-free.
11. The bushing connects the internal windings of the transformer to the external electrical network.
