-CORE
The core is manufactured from cold-rolled grain oriented, (CRGO) silicon steel. The steel sheets are cut into required dimensions on automated machines thereby ensuring reduced air gap, low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.-WINDINGS
LV winding is manufactured with high quality foil conductor or copper wire, and the ampere-turn is balanceable. The additional loss is low and the ability of anti-short is improved. Oil drawings of heat dispersion are scientifically used in the winding, and the surface of heat dissipation is increased, so the temperature is reduced and the ability of over-load is improved.
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 OIL
The insulating oil is inhibited, without PCB and generally complies with IEC60296.
