30-2500KVA Capacity High Quality Copper Three Phase Oil Immersed Transformer

Overview of 30-2500KVA Capacity High Quality Copper Three Phase Oil Immersed Transformer

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.

Features of 30-2500KVA Capacity High Quality Copper Three Phase Oil Immersed Transformer

• 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.

Specifications of 30-2500KVA Capacity High Quality Copper Three Phase Oil Immersed Transformer

These transformers handle power needs from 30 to 2500 kilovolt-amperes. They are built tough for demanding industrial settings. High-purity copper forms the core windings. Copper conducts electricity better than alternatives. This means lower energy losses during operation. Less wasted energy saves money over the transformer’s long life. Copper also handles overloads better. The transformer lasts longer.

The design is three-phase. This matches standard industrial power systems. It provides stable voltage for heavy machinery. The transformer core sits immersed in high-grade insulating oil. This oil cools the windings effectively. It prevents dangerous overheating. The oil also provides superior electrical insulation. It protects internal components.

Voltage ratings are flexible. Common primary voltages include 11kV, 33kV. Secondary voltages match your equipment, like 415V or 690V. Custom combinations are possible. These transformers meet strict IEC standards. They also comply with local regulations. Safety is paramount.

The tank construction uses strong welded steel. This prevents leaks. It protects the core and oil from the environment. The oil expands and contracts with temperature changes. A conservator tank accommodates this safely. Silica gel breathers keep moisture out. Moisture contamination harms performance.

Temperature rise limits are carefully controlled. This ensures reliable operation under load. Noise levels are kept low. These transformers run efficiently. They minimize wasted power. Reduced losses benefit your operating costs. Options include different tap changers. Tap changers adjust output voltage slightly. This compensates for supply variations. Radiators or cooling fins manage heat dissipation. Larger units might need fans. Basic protection is often built-in. This includes pressure relief devices and temperature gauges. External protection relays are recommended.

Applications of 30-2500KVA Capacity High Quality Copper Three Phase Oil Immersed Transformer

Large industrial facilities need reliable power distribution. Factories use these transformers every day. They step down high voltage electricity from the grid. Machines and lighting systems run safely on lower voltage. Consistent power prevents costly production stops. Power generation plants rely on them too. They connect generators to the transmission network. Wind farms and solar installations need this connection. Transformers handle variable power output from renewables. Construction sites often require temporary high-capacity power. These oil-filled units deliver that power reliably. They withstand demanding site conditions. Mining operations face harsh environments. Dust, moisture, and vibrations are common. Robust oil-immersed transformers manage these challenges. They power heavy extraction machinery underground or at the surface. Hospitals and data centers cannot tolerate power interruptions. These transformers provide critical backup power support. They integrate seamlessly with emergency generator systems. Water treatment plants depend on uninterrupted operation. Transformers ensure pumps and filtration systems run continuously. Public safety and health depend on clean water. The copper windings inside offer high efficiency. Less energy gets lost as heat during voltage changes. This saves money over the transformer’s long life. The mineral oil insulation provides excellent cooling. It allows the transformer to handle heavy loads safely. Overload conditions are managed effectively. Fire safety is a major benefit. The oil has a high ignition point. This reduces fire risks significantly. Maintenance is straightforward. Units are designed for long service life.

5 FAQs of 30-2500KVA Capacity High Quality Copper Three Phase Oil Immersed Transformer

What safety standards do these transformers meet?
They meet all major international safety standards. IEC standards cover basic safety. IEEE standards cover performance in tough conditions. Local regulations like UL or CE are also met. Testing includes lightning strikes, short circuits, extreme temperatures. This ensures safe operation everywhere.

Why use copper instead of aluminum windings?
Copper conducts electricity better than aluminum. This means less energy wasted as heat. Copper handles heavy loads better without overheating. It lasts much longer too. Copper is stronger physically. It resists damage better over decades of use. The higher upfront cost pays off long-term.

How are these transformers cooled?
They sit in special oil inside a strong tank. The oil absorbs heat from the core and windings. Heat moves to the tank walls. Air flowing over the tank cools the oil. Larger units use radiator fins or tubes. This increases the cooling surface area. Some big units add fans for extra cooling during peak loads.

What is the expected lifespan?
Properly maintained, expect 25 to 40 years of service. Good quality materials matter. Correct installation matters. Regular maintenance is key. This includes checking oil quality and cleaning parts. Avoiding constant overload helps. The environment affects lifespan too. Clean, dry, moderate-temperature sites are best.

Can I get a custom-designed transformer?
Yes, custom designs are available. Common changes include special voltage ratios. Different tap changers are an option. Unusual cooling methods can be specified. Unique tank shapes or mounting points are possible. Special protection features are doable. Give us your exact requirements early. We engineer solutions for specific needs.
