Fully hermetically sealed oil tanks, effectively preventing air ingress and prolonging transformer life.
OUTLINE DRAWING
CONSTRUCTION:
CORE
Manufactured from cold-rolled grain-oriented (CRGO) silicon steel, our core is cut to required dimensions with automated machines, ensuring reduced air gaps, low exciting current, and low noise. Each lamination is insulated from the other, guaranteeing a long, trouble-free core lifetime. Using 45° stepping all leaning lamination techniques efficiently reduces no-load current.

WINDINGS
Our LV windings are crafted from high-quality foil conductor or copper wire, balancing ampere-turns to minimize additional loss and enhance short-circuit resistance. Heat dispersion in the windings is scientifically managed, increasing heat dissipation surface area, thereby reducing temperature and improving overload capacity.
Reducing temperature and enhancing overload capacity.
HV winding is manufactured with high quality copper wire and excellent design structure. It improves the distribution of electric field. With lighting
impulse analysis, the ability of anti-lighting impulse has been improved.
TANK
The tank is jointed with high-quality steel. The surface is eliminated rust phosphate coating and pained with the type of FVC anticorrosive paint. It has
ability to prevent the corrosion from oil and chemical matter. It can be broadly applied to outdoors with bad environment for its contour artistic, easily
installation and maintenance free.
INSULATION OI L
The insulating oil is inhibited, without PCB and generally complies with IEC60296.

Process 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 noload 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.
