ISO Certified 11kV 500KVA Step-Up Oil Immersed Power Transformer for Wind Farms

Overview of ISO Certified 11kV 500KVA Step-Up Oil Immersed Power Transformer for Wind Farms

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 ISO Certified 11kV 500KVA Step-Up Oil Immersed Power Transformer for Wind Farms

• 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.

Applications of ISO Certified 11kV 500KVA Step-Up Oil Immersed Power Transformer for Wind Farms

Wind farms generate electricity. Turbines usually produce power at lower voltages. This voltage needs boosting for efficient long-distance travel. Our ISO certified 11kV 500KVA step-up oil immersed power transformer handles this job perfectly.

It takes the electricity directly from the wind turbine. The transformer increases the voltage level significantly. Typical input might be around 690V. The output reaches 11,000 volts (11kV). This high voltage reduces energy losses significantly. Power travels much farther over transmission lines this way.

These transformers are built tough for wind farm life. They sit near the turbines. Outdoor conditions are harsh. Wind, rain, dust, and temperature swings happen constantly. The robust oil-immersed design protects internal parts. Oil cools everything inside. It also insulates vital components. This ensures stable operation year after year.

Reliability is non-negotiable in remote wind locations. Downtime costs money. Our transformer uses proven oil-immersion technology. This offers excellent overload capacity. It handles the variable power output from wind gusts smoothly. Consistent performance keeps the farm generating power.

Safety and quality are paramount. The transformer meets strict international standards. ISO certification proves this. It means rigorous manufacturing controls exist. Every unit undergoes thorough testing. You get a dependable product designed for critical infrastructure. Installation and maintenance are straightforward. The design focuses on long service life with minimal fuss.

5 FAQs of ISO Certified 11kV 500KVA Step-Up Oil Immersed Power Transformer for Wind Farms

What does ISO certification mean for this transformer?
ISO certification proves this transformer meets strict international standards. It ensures high quality, reliability, and safety. You get a product built to perform consistently in demanding wind farm conditions. This certification gives you confidence in its long-term operation.

Why is 11kV 500kVA the right size for wind farms?
This size is common for connecting individual wind turbines or small groups. It steps up the turbine’s lower output voltage (like 690V) to 11kV. This higher voltage is efficient for sending power longer distances across the farm to the main substation. The 500kVA capacity matches typical turbine outputs well.

Why choose an oil-immersed transformer here?
Oil-immersed transformers handle high power loads reliably. The oil is excellent insulation. It also carries heat away effectively. This keeps the transformer cool under heavy, sometimes fluctuating, wind generation. They are robust and proven for outdoor use, perfect for remote wind farm locations.

How does it cope with changing wind power?
This transformer is built tough. It handles the variable power output from wind turbines smoothly. Special design features manage the load swings and potential harmonics common in wind generation. It provides stable voltage output even when wind speeds change.

What about installing this transformer?
Installation needs careful planning. The site must be level and stable. You need proper foundations. Access for delivery and maintenance vehicles is crucial. Safety clearances around the transformer are mandatory. Always follow the manufacturer’s instructions and local electrical codes exactly. Professional installation is essential.
