Cast Resin Insulated Water-cooled Phase Shifting Transformer
Product Description
The water-cooled phase-shifting transformer is a special transformer that combines phase-shifting technology and water-cooling heat dissipation. It is mainly used in high-power rectifier systems (such as high-voltage inverters, ship electric propulsion systems, etc.). Its core function is to achieve multi-pulse rectification through phase difference phase shifting, thereby effectively reducing harmonic content and improving power quality. At the same time, the water cooling system solves the heat dissipation problem during large-capacity operation.
Transformer Features:
In dry-type water-cooled transformers, cooling water circulates through pipelines for heat dissipation. Its core component is a high-temperature nano insulator, which has high insulation strength and stability, ensuring the safe and stable operation of the transformer. During the operation of the transformer, the heat generated inside the transformer is transferred to the high-temperature nano insulator and then transferred to the transformer casing through the thermal conductivity pipeline of the high-temperature insulator. Then, the accumulated heat of the transformer is discharged through the heat exchanger and water circulation system, achieving the cooling of the transformer. This cooling method is more efficient than traditional natural air cooling and forced air cooling methods, improving the cooling capacity and efficiency of transformers and making them more energy-efficient.
The dry-type water-cooled transformer designed and produced by Pearl Electric has the following characteristics:
1.High efficiency: Dry water-cooled transformers use water as the cooling medium, which has a higher cooling efficiency compared to traditional oil immersed transformers and can quickly remove the heat generated by the transformer.
2.Environmental protection: As oil is not used as the cooling medium, dry-type water-cooled transformers will not produce environmental pollution problems such as oil leakage, which meets environmental protection requirements.
3.Fire and explosion prevention: Dry water-cooled transformers have the advantage of being less prone to ignition and explosion, and have higher safety.
4.Space saving: Dry water-cooled transformers have a compact structure and occupy less space compared to traditional oil immersed transformers, making them suitable for use in environments with limited space.
5.Easy maintenance: The cooling system of dry-type water-cooled transformers is usually integrated with the transformer for easy maintenance and repair.
6.High reliability: Dry type water-cooled transformers adopt a dry design, which has higher reliability compared to oil immersed transformers and can ensure long-term stable operation of the transformer.
7.Wide applicability: Dry type water-cooled transformers are suitable for various working environments and power demands, such as electricity, industrial and mining enterprises, and urban construction.
The dry-type water-cooled transformers designed and produced by Pearl Electric are applied in multiple fields, which can meet the power and heat dissipation requirements of different fields and industries.

Description about Three Phase Dry Type Power Distribution Transformer Enclosure
A dry type transformer, also known as an air-cooled transformer, is a type of transformer that utilizes air or gas instead of liquid (such as oil) for insulation and cooling purposes. This transformer design does not immerse its core and windings in insulating oil, making it distinct from oil-filled transformers.
Types of Dry Type Transformers:
- Cast Resin Dry Type Transformer (CRT):
- Uses epoxy resin to encapsulate windings, protecting them from moisture, dust, corrosion, and other environmental factors.
- Suitable for high humidity areas, indoor installations, and fire-risk areas due to its non-hygroscopic, non-inflammable, and maintenance-free nature.
- Available in ratings from 25 kVA to 12,500 kVA, with an insulation class of F (90°C temperature rise).
- Vacuum Pressure Impregnated Transformer (VPI):
- Impregnates windings with class H polyester resin under vacuum and pressure, eliminating air gaps or voids in the insulation.
- Enhances mechanical strength, dielectric strength, and thermal stability.
- Suitable for outdoor installations, seismic events, and temperature fluctuations due to its robust construction, moisture-resistant enclosure, and low thermal expansion coefficient.
Pearl Electric, an experienced transformer manufacturer since 1958, design and produce various cast resin dry type transformer for different application include rectification transformer, marine/offshore oil platform transformer, rectification traction transformer, Transformer for electrified railway station, Rectification excitation transformer etc.
