Product Description

Product Description:

Our products encompass a wide capacity range from 10 MVA up to 200 MVA. This extensive range ensures flexibility and adaptability for various applications.

We are committed to addressing the diverse requirements of different scenarios, including industrial power supply systems. Our solutions are designed to reliably support industrial operations with the appropriate power capacity.

In addition, our equipment is well-suited for new energy grid connections, facilitating the integration of renewable energy sources into the power network. This enables efficient and sustainable energy distribution tailored to modern grid demands.


Features:

The core material employed in this product consists of high magnetic conductivity cold-rolled silicon steel sheets. To minimize no-load losses, advanced laser cutting and stacking techniques are utilized during the manufacturing process.

For the winding process, copper wire is carefully wound and then subjected to vacuum drying and insulation treatments. This approach effectively ensures that the local discharge capacity remains at or below 5 picoCoulombs (pC), enhancing the overall performance and reliability.

In terms of sealing technology, a double-layer sealing structure is implemented, which includes both a rubber gasket and a metal flange. This design undergoes a rigorous 24-hour leakage test to guarantee that no leakage occurs, thereby maintaining the integrity and durability of the product.


Applications:

We offer reinforced insulation design tailored to withstand challenging conditions. This specialized design ensures that equipment remains protected and functional even in environments characterized by extreme factors.

Additionally, our solutions include anti-corrosion coatings that safeguard equipment against the damaging effects of high humidity, salt spray, and the thin air found at high altitudes. These protective measures play a crucial role in maintaining the integrity of the equipment over time.

By combining reinforced insulation with advanced anti-corrosion treatments, we significantly enhance the durability and lifespan of your equipment, ensuring reliable performance in harsh environmental conditions.


Support and Services:

Our Oil Immersed Power Transformers are designed to provide reliable and efficient performance in a wide range of electrical applications. To ensure optimal operation and longevity of your transformer, we offer comprehensive technical support and services.

Our technical support team is available to assist with installation guidance, troubleshooting, and maintenance best practices. We provide detailed documentation, including user manuals, wiring diagrams, and testing procedures to facilitate proper handling and operation.

Regular maintenance services such as oil testing, cleaning, and inspection are recommended to prevent potential issues and extend the life of the transformer. We offer scheduled maintenance programs and on-site inspection services performed by qualified technicians.

In case of any operational concerns or faults, our support specialists are equipped to provide diagnostic assistance and recommend corrective actions. We also provide repair and refurbishment services to restore transformer performance to original specifications.

For upgrades or customization needs, we work closely with customers to tailor solutions that meet specific voltage, capacity, or environmental requirements. Our commitment is to deliver exceptional service and ensure the continuous reliability of your Oil Immersed Power Transformer.
