Three Phase Cast Resin Water Cooling Dry Type Transformerer
Product Description
Transformer Description:
A dry-type water-cooled transformer is a type of dry-type transformer that uses water as the cooling medium. It is based on dry-type transformers, combining water and dry-type transformers to form a new type of transformer.
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.

Transformer Chracteristics
Transformer Core
1. The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-step overlapping method to reduce the no-load loss and no-load current.
2. Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.
3. Flexible connections are adopted between the core and coils, core and clamps. With these measures, transformer's noise level has been improved by 10-15dB over the conventional products.
Transformer Windings
LV windings
1. For LV windings above 400 kVA capacity, superior foil conductors are adopted for winding manufacturing, thus to obtain better amper-turn balance and less transverse magnetic flux leakage, and finally to greatly improves transformer's anti-short circuit capability.
2. By reasonably designing the oil passage within the winding, winding's heat dispersion effect is greatly increased. Thus the reasonable design has decreased temperature rise and improved products' overload capability.
HV windings
1. HV windings are manufactured with superior wire conductors, insulated reinforced with fiber glass.
2. The HV windings are cast under vacuum and high pressure conditions in Germany HUBERS vacuum Cast Machine, resulting the best resin penetration and very low partial discharge( partial discharge for 11kV product could be lower than 5Pc).
3. Optimized structure is adopted for HV windings to improve transformer's electric field. Lighting impulse simulation calculation was adopted for winding model design, thus to substantially improve product's anti-lighting capability.
