Cast Resin Dry Type Transformer is a type power transformers with windings casted in epoxy resin without any insulating liquid which is widely used in different application and can be installed indoor and outdoor.
1.Phase: 3 phases
2.Rated power: 1000kVA
3. Primary voltage: 6kV
4. Secondary voltage: 0.4kV
5. Frequency: 50Hz
6. Vector group: Dyn11
7. Insulation class: H/F Class
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.
1. For LV windings above 400 kVA capacity, superior foil conductors are adopted for winding manufacturing, thus obtaining better amper-turn balance and less transverse magnetic flux leakage, and finally to greatly improves the transformer’s anti-short circuit capability.
2. By reasonably designing the oil passage within the winding, the winding’s heat dispersion effect is greatly increased. Thus the reasonable design has decreased temperature rise and improved products’ overload capability.
1. HV windings are manufactured with superior wire conductors, insulated reinforced with fiberglass.
2. The HV windings are cast under vacuum and high-pressure conditions in Germany HUBERS vacuum Cast Machine, resulting in 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 the transformer’s electric field. Lighting impulse simulation calculation was adopted for winding model design, thus substantially improve the product’s anti-lighting capability.
