1000 KVA Cast Resin Dry Type Transformer

About 1000 kVA cast resin dry type transformer

In 2021, we delivered 2 units of 1000 kVA cast resin dry type transformer to our Canadian client for their medical facilities. These three phase dry type transformer have a primary voltage of 11kV, secondary voltage of 0.33kV, and a capacity of 1000 KVA. Their vector group is Yy0d11, with ANAF cooling. These cast resin dry type transformer primarily consist of iron cores and coils encapsulated in epoxy resin. Insulating sleeves are placed between the high and low voltage coils to enhance electrical insulation, supported and constrained by spacers. EverNew delivers tens of thousands of transformers of various types to global clients each year. Contact us for factory price, high-quality transformers.

Dry Type Transformer – Insulation Class

Dry Type Transformer Core

EverNew employs high-quality transformer cores crafted from Cold Rolled Grain Oriented (CRGO) steel. These silicon steel sheets undergo precision manufacturing processes, where automated machines cut them to the required dimensions. This meticulous approach minimizes air gaps, reduces excitation current, and lowers noise levels, ensuring optimal transformer performance.

To enhance durability and reliability, each laminated layer of the core is carefully insulated from one another. This insulation not only prevents electrical faults but also extends the lifespan of the iron core.

Our cores are stacked using a 45-degree stepped full tilt method, a technique that effectively reduces no-load current. This innovative approach to core stacking further enhances the efficiency and performance of our transformers.

Dry Type Transformer Winding

Low-Voltage Winding: The low-voltage winding is crafted using high-quality foil conductors or copper wires, ensuring balanced turns for optimal performance. It exhibits minimal additional losses and boasts strong resistance against short-circuit scenarios. Scientifically designed, the winding incorporates a cooling oil circulation system to enhance heat dissipation, effectively lowering temperature rise and thereby boosting overload capacity.

High-Voltage Winding: The high-voltage winding is constructed using premium-grade copper wires, featuring an exceptional structural design that enhances the distribution of the electric field. Through rigorous lightning impulse analysis, it has been fortified to withstand lightning strikes effectively.
