High-Reliability 13200V 400V 630KVA Three Phase Dry Type Transformer
Product Description
Description about Three Phase Dry Type Transformer
Three phase dry-type transformers offer a reliable, safe, and environmentally friendly solution for various electrical distribution needs. Their robust design and insulation make them ideal for use in challenging environments, while their low maintenance requirements and high safety standards make them a preferred choice in many applications.
Features of Three Phase Dry Type Transformer
- Low Maintenance: The absence of oil means there's no need for regular oil sampling, filtration, or replacement, resulting in lower maintenance costs and easier upkeep.
- Design Flexibility: Dry type transformers come in various designs, including cast resin (CRT) and vacuum pressure impregnated (VPI) types. CRT transformers use epoxy resin to encapsulate windings, while VPI transformers impregnate windings with polyester resin under vacuum and pressure.
- Applications: They are widely used in industries and applications requiring high safety standards and environmental compatibility, such as local lighting, high-rise buildings, airports, tunnels, and nuclear power plants.
- Performance Factors: The efficiency and suitability of dry type transformers for different environments are significantly impacted by design choices like insulation type and winding material.

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.
