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.
