Resin Voltage Transformer Core Distribution Gap Core

Resin Voltage Transformer Core Key features and benefits

Distributed gap design:

Instead of a single air gap, the core's magnetic circuit has many small gaps distributed along its length. This configuration, often achieved with step-lap joints between laminations, reduces core losses and noise.

Shell-type configuration:

The windings are wrapped around the core, which is itself formed around the windings, making it a shell-type design. This helps maximize the transfer of magnetic flux and is common for distribution transformers.

Resin encapsulation:

The entire core and coil assembly is encased in epoxy resin through a vacuum casting process. This process ensures the resin penetrates all gaps, creating a solid, dry-type transformer that is moisture, dirt, and corrosion-resistant.

Cost-effective manufacturing:

The simple core clamp design and single cut per lamination layer make the distributed gap core faster and cheaper to manufacture.

Improved efficiency:

The distributed gap design is efficient, has lower core losses, and is suitable for high-frequency applications like those found in renewable energy systems.

Distribution Gap Core Applications

Distribution transformers:

The design is widely used in single-phase and three-phase pole-mounted distribution transformers.

Renewable energy:

It is a common choice for transformers in renewable energy systems due to its efficiency and suitability for high-frequency operation.

Space-constrained environments:

The compact nature of this design makes it ideal for applications where space is limited.
