Product Description

Product Description:

Our product line spans a wide capacity range from 10MVA to 200MVA, designed to cater to diverse requirements across various applications.

This extensive range ensures that we can meet the specific demands of different scenarios, whether it be industrial power supply systems or the integration of new energy sources into the grid.

By offering solutions suitable for both traditional industrial usage and modern renewable energy connections, we provide flexible and reliable options tailored to your unique power needs.


Features:

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

For the winding procedure, copper wire is utilized and is subjected to vacuum drying and insulation treatments. These steps are essential to guarantee that the local discharge capacity remains at or below 5 picocoulombs (pC), ensuring high electrical performance.

Regarding the sealing technology, a double-layer sealing structure is implemented, which includes a rubber gasket combined with a metal flange. This robust design undergoes a rigorous 24-hour leakage test, confirming the product’s integrity and ensuring there is no leakage.


Applications:

We offer reinforced insulation design to ensure optimal performance and safety in demanding conditions. This robust insulation solution is specifically engineered to withstand the challenges presented by harsh environments.

In addition, our equipment is treated with anti-corrosion coatings that provide excellent protection against factors such as high humidity, salt spray, and other corrosive elements commonly found in severe climates.

By combining these advanced design and coating techniques, we effectively extend the operational life of the equipment, making it reliable and durable even in high altitude and other extreme environmental conditions.


Support and Services:

Our Oil Immersed Power Transformer product comes with comprehensive technical support and services to ensure optimal performance and longevity. We offer expert installation guidance, routine maintenance schedules, and troubleshooting assistance. Our team of skilled engineers is available to provide on-site support and remote diagnostics to quickly resolve any operational issues. We also provide detailed product manuals, testing services, and upgrade options to meet evolving industry standards and customer requirements.
