Pearl Electric's Technology
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.
