Core:
- Our transformer's core is made of high quality cold rolled grain oriented silicon steel sheet with high magnetic permeability. It is using full 45° slope lamination, so that the no-load loss and the no-load current are reduced efficiently.
- We use Simulating Analysis in the core model design, so that we can calculate the frequency and size of the vibration exactly and avoid the core cavity resonance.
- Between core & windings, and core & frame, we use spring connection. Then the noise is lower 10 to 15dB than the standard.
LV Winding:
- LV windings, above 400 kVA capacity, are adopting superior foil conductors, thus to obtain better amper-turn balance and reduce more transverse magnetic flux leakage. Then to greatly improves transformer's anti-short circuit capability.
- The wise design of air passage within the winding, greatly increasing the winding's heat dispersion effect. It helps to decrease temperature rise and improve products' overload capability.
HV Winding:
- HV windings are made of superior copper-conductor wires. Adopting fiberglass to reinforced insulation.
- The HV windings are casting under vacuum and high pressure conditions with Germany HUBERS vacuum Cast Machine. In this way, transformer's resin can get the best penetration. It can also greatly reduce its partial discharge (partial discharge for 11kV product could be lower than 5pC).
- HV windings are adopted optimized structure to improve transformer's distribution of electric field.
- We use our existing technology calculate and analysis Lightning wave process simulation. Then substantially improving product's anti-lighting capability.
