Overview of 800kva 1000kva 1250kva 2000kva 2500kva Oil Immersed Power Transformer 380V/480V/50Hz Three Phase 15kv/35kv/6kv Input 50Hz

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

These oil immersed power transformers handle large power needs reliably. They come in common sizes: 800kVA, 1000kVA, 1250kVA, 2000kVA, and 2500kVA. They step down higher voltages to usable levels for factories or big buildings. The primary input voltage options are 15kV, 35kV, or 6kV. The secondary output voltage is either 380V or 480V. All units operate at the standard 50Hz frequency. They are three-phase transformers.

The transformer core uses high-grade electrical steel. This minimizes energy losses. Copper or aluminum windings conduct the electricity efficiently. The whole active part sits inside a strong steel tank. The tank is filled with high-quality insulating mineral oil. This oil is crucial. It cools the windings and core. It absorbs the heat generated during operation. The oil also provides excellent electrical insulation. It prevents internal arcs or short circuits.

The oil circulates naturally. Heat rises. Cooler oil sinks. This natural flow keeps temperatures stable. Larger units may have radiators. Radiators increase the cooling surface area. This improves heat dissipation. A conservator tank is usually present. It holds extra oil. The oil level changes with temperature. The conservator allows for this expansion and contraction. It keeps the main tank full. A silica gel breather is attached. It stops moisture from entering the oil. Dry oil is essential for good insulation.

These transformers are built tough. They withstand demanding industrial environments. The steel tank protects the internal components. It resists corrosion. Safety features are included. Pressure relief devices vent excess pressure quickly. Temperature gauges monitor oil heat levels. Oil level indicators show the amount of oil present. These features help prevent failures. They ensure long service life. Installation needs proper planning. Consider the weight and size. Adequate ventilation is important. Regular maintenance checks are necessary. Check oil quality and levels. Inspect connections. These steps guarantee reliable, safe power distribution for years.

Applications of 800kva 1000kva 1250kva 2000kva 2500kva Oil Immersed Power Transformer 380V/480V/50Hz Three Phase 15kv/35kv/6kv Input 50Hz

These oil-immersed power transformers handle big industrial power needs. They convert higher incoming voltages down to usable levels. Models range from 800kva to 2500kva. This covers many demanding applications. They accept input voltages like 15kV, 35kV, or 6kV. The output is 380V or 480V. All operate at 50Hz, three-phase. Oil cooling ensures they manage heavy loads reliably.

Factories use these transformers constantly. Large manufacturing plants need them. A 1000kva unit often powers heavy machinery lines. It provides stable 380V or 480V power. Steel mills or cement plants require even larger units. A 2000kva or 2500kva transformer handles their immense power demand. It steps down 35kV grid power efficiently.

Mining operations depend on robust power. An 800kva or 1250kva transformer suits remote mining sites well. It connects to 15kV or 35kV distribution lines. It powers drills, crushers, and processing equipment. Oil insulation protects against harsh, dusty mine environments.

Utilities deploy these transformers too. They act as distribution substations in smaller towns or industrial parks. A 1250kva unit stepping 35kV down to 400V is common. It feeds power to multiple buildings or a small factory complex.

Large buildings need reliable power. Hospitals, data centers, and shopping malls use them. A 1000kva transformer provides essential backup power capacity. It ensures critical systems stay online during grid issues. Water treatment plants require continuous operation. A 2000kva transformer powers large pumps and filtration systems. It handles the high starting currents reliably.

Renewable energy projects utilize these transformers. A 2500kva unit might connect a mid-sized solar farm to the 35kV grid. It steps up the generated voltage for efficient transmission. Oil cooling handles the variable load patterns well. These transformers are workhorses. They deliver power where high capacity and durability are non-negotiable. They form the backbone of industrial and critical infrastructure power systems.
