Product Name: 12500kVA 33/11kV Oil Immersed Power Distribution Transformer: Experience the pinnacle of power management with our 12500kVA 33/11kV Oil Immersed Power Distribution Transformer. Designed to meet the highest industry standards, this transformer promises exceptional durability, superior efficiency, and seamless integration into any distribution system, ensuring a steady and reliable power supply.
The rated voltage is highly customizable to meet the unique requirements of our esteemed customers.
Our state-of-the-art, fully sealed oil-immersed power transformer, engineered with precision by TSTY, boasts superior features such as
exceptionally low loss, minimal noise, and outstanding efficiency, delivering remarkable energy-saving capabilities and significantly reducing environmental impact. Unlike conventional oil-immersed transformers, our innovative fully sealed model eliminates the need for an oil conservator. The dynamic adjustment and compensation for oil volume changes are seamlessly managed by the flexible corrugated sheets of the corrugated oil tank. This design ensures that the transformer remains isolated from air, effectively preventing oil deterioration and insulation aging. Consequently, it enhances operational reliability and eliminates the need for routine maintenance.
Main Components:
The primary components of the 33/11kv Electrical Power Supply Transformer 12500kVA from TSTY ELECTRIC CO., LTD. include: Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank, designed to immerse windings, ensures optimal cooling and insulation.
2. Compliant with IEC standards and certified with CE/ISO.
3. Ensures seamless contact and expands under load, facilitating efficient oil temperature regulation.
4. The Buchholz relay, essential for conservator tanks, detects issues such as low oil levels and improper oil flow between the tank and transformer.
5. The Breather Unit, containing silica gel, absorbs moisture, changing color from blue to pink when saturated.
6. The oil indicator measures the oil level within the conservator unit.
7. The temperature detector tracks oil temperature, disconnecting the transformer if it exceeds safe limits.
8. The pressure relief device mitigates pressure buildup within the transformer, preventing potential explosions.
9. The thermal relay provides winding temperature alerts for safety.
10. Fully galvanized coating ensures rust-free durability.
11. The bushing connects internal windings to an external electrical network efficiently.
