Basic Info.

This dry type transformer is configured for a 6kV high-voltage input and 0.4kV low-voltage output. It is suitable for medium-voltage distribution systems where reliable power conversion is required for downstream electrical equipment and loads.

With a rated capacity of 2500kVA, this transformer is designed for high-capacity power distribution applications. It can be used in industrial facilities, commercial buildings, infrastructure projects and other medium-voltage distribution systems.

The transformer adopts a Dyn11 connection group, a widely used configuration for three-phase distribution transformers. This connection provides a suitable electrical configuration for medium-voltage power distribution systems.

The transformer uses aluminum windings as a cost-effective winding solution for the project. The winding design is selected according to the rated capacity, voltage level and operating requirements.

The transformer has an impedance voltage of 8%. Transformer impedance is an important design parameter that affects short-circuit current and voltage regulation in the distribution system.

The appropriate impedance value should be selected according to the system short-circuit capacity, voltage regulation requirements and overall project conditions.

The transformer adopts natural air cooling, using natural air circulation to dissipate heat generated during operation. This provides a simple cooling configuration with low maintenance requirements for dry type transformer applications.
