100kva 200kva 300kva Copper Winding Transformer 315kva 400kva 500kva Oil Immersed Transformer

Overview of 100kva 200kva 300kva Copper Winding Transformer 315kva 400kva 500kva 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 100kva 200kva 300kva Copper Winding Transformer 315kva 400kva 500kva 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.

These transformers handle power needs from 100kVA to 500kVA. They use copper windings. Copper conducts electricity very well. This means less energy loss as heat. It also means the transformer runs cooler overall. These transformers last longer because of copper.

The core uses high-grade silicon steel. This steel reduces magnetic losses significantly. Less energy wasted means better efficiency. Efficiency meets or beats industry standards like IEEE or IEC. This saves money on electricity bills over time.

The transformer sits in a strong steel tank. The tank is filled with insulating oil. This oil cools the core and windings. It also provides vital electrical insulation. The oil circulates naturally as it heats up. This is called ONAN cooling. It’s simple and reliable. Larger units might have extra cooling options available.

Voltage ratings are flexible. Primary voltage options include 11kV, 22kV, 33kV. Secondary voltage is often 415V or 400V. Other voltages are possible. Specify your input and output needs. The transformer handles step-down applications. It connects high voltage lines to lower voltage equipment.

Protection features are standard. The tank includes an oil conservator. This keeps the oil level stable as temperature changes. A Buchholz relay detects internal gas bubbles. This signals potential faults early. A pressure relief device prevents tank rupture. A silica gel breather keeps moisture out of the oil.

These units are built for stability. They maintain consistent voltage output. They handle overloads well for short periods. They are tough and reliable for industrial sites. They work well outdoors. They withstand harsh weather conditions.

Accessories include temperature gauges. These monitor oil temperature. Tap changers adjust the output voltage slightly. Wheels or skids make moving the transformer easier.

Applications of 100kva 200kva 300kva Copper Winding Transformer 315kva 400kva 500kva Oil Immersed Transformer

These transformers handle large power needs. They step down high voltage electricity to safer, usable levels. Factories use them for heavy machinery. Hospitals rely on them for critical equipment power. Big buildings need them for lighting, elevators, and HVAC systems. Construction sites use them for temporary power. Water treatment plants depend on them for pumps and controls.

The copper windings inside are key. Copper conducts electricity very well. This means less energy lost as heat. Less energy loss saves money over time. Copper windings also handle overloads better. They are strong and last long. This makes the transformer durable.

The oil inside is vital. It cools the transformer. Heat is the enemy of electrical equipment. The oil absorbs heat from the copper and core. It carries the heat away to the tank walls. The oil also insulates the internal parts. This prevents dangerous short circuits. It protects the transformer.

These transformers are built tough. They work outside. They handle weather like rain, wind, and sun. Their strong tanks protect the core and windings. They need little maintenance. Oil checks and cleaning are the main tasks. They are reliable power sources. You see them on concrete pads or poles. They power essential operations. Their size fits the power demand. Choose 100kva, 200kva, 300kva, 315kva, 400kva, or 500kva based on your load. They deliver stable voltage where large equipment runs.

100kVA to 500kVA Oil-Immersed Transformers with Copper Windings: Key Questions Answered

What exactly are these oil-immersed transformers?
These are power transformers. They change electrical voltage levels. They are built for heavy-duty use. The transformer core and windings sit inside a strong steel tank. This tank is filled with special insulating oil. The oil cools the transformer. The oil also provides vital electrical insulation.

Where are these transformers typically installed?
You find these units in demanding locations. Industrial factories rely on them. Large commercial buildings need their power. Power substations use them. Mining operations depend on them. They handle the main power distribution. They step down high voltage from the utility. They provide usable voltage for machinery and buildings.

What makes the construction robust?
The core uses top-grade electrical steel. This minimizes energy losses. The windings are made from high-conductivity copper. Copper is the key. Copper windings last longer. Copper handles heat better. Copper provides excellent electrical efficiency. The entire assembly sits securely in the tank. The oil surrounds everything. This protects the windings.

How does the oil cooling system work?
The oil absorbs heat from the core and windings. Hot oil naturally rises. Cooler oil sinks. This creates circulation. Heat moves to the tank walls. Radiator fins attach to the tank. Air flows over these fins. This cools the oil. Larger units (like 400kVA, 500kVA) might have bigger radiators. Some have fans for extra cooling. The oil keeps temperatures safe.

Why choose copper windings over aluminum?
Copper is the superior conductor. Copper windings are more efficient. They waste less power as heat. This saves energy costs over years. Copper handles overloads better. Copper is stronger mechanically. Copper connections are more reliable long-term. Copper windings mean a smaller, more compact transformer for the same power. The initial cost is higher. The lifetime value is better.
