Product Cases

Dry-type Transformer

Transformer core is the core component of dry-type transformers. It works with windings to transmit magnetic flux, supporting voltage conversion and stable operation. It also helps reduce energy loss and operating noise.

Power Distribution Transformer

The core is the magnetic heart of a power transformer. It forms a closed magnetic path to transfer alternating flux between windings, enabling voltage transformation.

Oil-immersed Transformer

In oil-immersed transformers, the core is submerged in insulating oil. The oil cools the core and provides insulation, supporting stable, high-power operation with low noise.

Box-type Substation

The core is an indispensable key part of box-type substations. It ensures stable power distribution and adapts well to harsh outdoor conditions.

Transformer Core Assembly

The core relies on meticulous assembly to maintain fine magnetic performance. Proper fitting keeps the core working efficiently for long term.
