Specifications of Three Phase 200KVA 250KVA 10/0.4KV Electric Transformers Cooling Fan Dry Type Transformer

This transformer handles three-phase power. It comes in two sizes. Choose 200kVA or 250kVA. It steps down voltage from 10kV to 400V. The transformer uses air for cooling. It is a dry type. No oil is inside. This makes it safer. It also means less maintenance. The transformer has a special cooling fan. This fan helps a lot. It keeps the transformer cool under heavy loads. The fan turns on automatically. It activates when the transformer gets too hot. The fan turns off when things cool down. This saves energy. It also makes the transformer last longer.

The core uses high-grade silicon steel. This material is very efficient. It reduces energy losses. The windings are copper. Copper conducts electricity well. The coils are coated. They use a tough resin. This resin protects the windings. It handles heat and moisture. The transformer meets international standards. Look for IEC 60076. It also has IP20 protection. Dust and small objects won’t harm it. Larger objects might. The design keeps noise low. It operates quietly. This is good for indoor places.

Installation is straightforward. Put it in a dry, ventilated room. Keep it away from walls. Air needs to flow around it. The transformer works reliably. It powers factories, buildings, and shopping centers. It works for hospitals and schools. It fits many commercial needs. The cooling fan ensures stable performance. This happens even during peak demand. The transformer is built strong. It offers dependable power distribution. Its design focuses on safety and efficiency.

Applications of Three Phase 200KVA 250KVA 10/0.4KV Electric Transformers Cooling Fan Dry Type Transformer

These transformers step down voltage safely. They take 10,000 volts from power lines. They convert it to 400 volts for buildings and factories. This dry type design uses no oil. It stops fires and leaks. It works well indoors and outdoors.

The 200KVA and 250KVA sizes handle big loads. They power entire workshops or large buildings. Think manufacturing plants, hospitals, or big office complexes. They manage heavy machinery and large HVAC systems. They keep essential operations running.

Built-in cooling fans are crucial. They kick in when the transformer gets hot. This happens during peak demand times. The fans pull air over the coils. This prevents overheating. It allows the transformer to handle its full power rating. It extends the equipment’s life.

The 10kV primary connects to the utility grid. The 0.4kV secondary feeds your local distribution. This setup is standard for industrial power distribution. It ensures equipment gets the right voltage.

These transformers are tough. They resist dust and moisture. They operate reliably in tough conditions. Their design minimizes maintenance. You don’t need oil checks or containment. This saves time and money. Safety is a major benefit. No oil means no fire hazard. They are safe near people and other equipment. They are ideal for installations inside buildings. They fit in basements or electrical rooms.

You see them in many places. Factories rely on them for production lines. Hospitals need them for critical power. Data centers use them for server rooms. Commercial buildings depend on them for lighting and climate control. Water treatment plants use them for pumps. They are the backbone of reliable power distribution.

5 FAQs of Three Phase 200KVA 250KVA 10/0.4KV Electric Transformers Cooling Fan Dry Type Transformer

Here are five common questions about our 200KVA and 250KVA 10/0.4KV Dry Type Transformers with Cooling Fans:

What exactly is this transformer? It’s a three-phase electrical transformer. It steps down high voltage electricity (10,000 Volts) to safer, usable low voltage (400 Volts). It’s rated for either 200KVA or 250KVA capacity. The core and windings are completely dry, no oil. Cooling fans are attached.

Why does a dry transformer need cooling fans? All transformers get hot during operation. Natural air cooling works for smaller units. Larger transformers like 200KVA and 250KVA sizes generate more heat. The fans force air over the windings. This extra cooling stops the transformer from overheating. It lets the transformer handle its full rated power safely, especially in warm places or tight spaces.

How do the cooling fans operate? The fans turn on automatically. Built-in temperature sensors monitor the transformer’s heat. When the internal temperature gets too high, the sensors switch the fans on. The fans blow cool air across the transformer core and coils. This quickly lowers the temperature. When the transformer cools down enough, the sensors switch the fans off. This saves energy.

Are these transformers noisy with fans running? Dry type transformers are generally quieter than oil-filled ones. The cooling fans add some noise when they are on. The fan noise is a steady hum. It’s usually noticeable but not excessive. We design the fan systems to minimize noise. Consider the transformer’s location if very low noise is critical.

What maintenance do the cooling fans need? The fans require regular checks. Keep the fan blades and intake grilles clean. Dust buildup blocks airflow. Inspect the fans periodically for smooth operation. Listen for unusual noises like grinding. Check the fan power connections stay tight. Replace worn or damaged fans promptly. Good fan maintenance protects your transformer investment. Proper cooling extends the transformer’s working life.
