Product Description

Product Description:

Our products encompass a capacity range from 10 MVA up to 200 MVA, designed to cater to a wide variety of applications. This extensive range ensures that we can address the specific demands of diverse operational environments.

Whether it is for industrial power supply systems or integrating new energy sources into the grid, our solutions are tailored to meet the unique requirements of each scenario. This flexibility allows for optimized performance and reliability across different use cases.

By offering this broad capacity spectrum, we support the evolving needs of modern power infrastructure, facilitating seamless and efficient energy management in both traditional and renewable sectors.


Features:

The core material utilized is high magnetic conductivity cold-rolled silicon steel sheets. Advanced laser cutting and stacking techniques are employed to minimize no-load losses, enhancing the overall efficiency of the component.

For the winding process, copper wire is used and carefully wound. This is complemented by vacuum drying and insulation treatments to guarantee that the local discharge capacity remains at or below 5 picoCoulombs (pC), ensuring reliable electrical performance.

In terms of sealing technology, a robust double-layer sealing structure is implemented, consisting of a rubber gasket combined with a metal flange. This design successfully passes a rigorous 24-hour leakage test, providing assurance of leak-free operation.


Applications:

We offer a reinforced insulation design that ensures enhanced durability and safety for equipment operating in challenging conditions.

Our solutions include specialized anti-corrosion coatings that protect against the damaging effects of harsh environments, such as high altitude, excessive humidity, and salt spray exposure.

By implementing these protective measures, we significantly extend the operational life and reliability of the equipment, even under severe environmental stresses.


Support and Services:

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

Our technical support team is equipped to assist you with installation guidance, routine maintenance procedures, troubleshooting, and performance optimization. We provide detailed documentation, including user manuals, wiring diagrams, and maintenance schedules to help you operate your transformer safely and effectively.

Regular maintenance services are crucial for the longevity of oil immersed transformers. We offer scheduled inspection services that include oil testing, insulation resistance measurement, and thermal imaging to detect potential issues before they lead to failure. Our experts can also perform preventive maintenance and repairs to minimize downtime and extend the life of your equipment.

In addition to maintenance, we provide diagnostic services such as dissolved gas analysis (DGA) and partial discharge testing to monitor the health of the transformer’s insulation system. These services help in early detection of faults and allow for timely corrective actions.

For installations requiring customized solutions, our engineering team can offer design modifications and retrofitting services to meet specific operational requirements or to upgrade existing units for enhanced performance.

We are committed to supporting you throughout the lifecycle of your Oil Immersed Power Transformer, ensuring maximum reliability and efficiency in your power distribution network.
