Customized Oil-Immersed Power Distribution Transformer
Our Oil-Immersed Transformer series stands out with low noise, minimal loss, and reduced partial discharge. Featuring a rational structure, premium materials, scientific design, meticulous craftsmanship, and advanced testing methods, the series exhibits:
Exceptional dynamic thermal stability, robust short-circuit resistance, high lighting impulse resistance, and superior reliability.
Energy efficiency, economical operation, and maintenance-free performance.
Attractive design, compact size, and low installation and maintenance costs.
Performance and parameters meet or exceed IEC standards.
A fully hermetically sealed oil tank effectively prevents oil erosion, prolonging transformer lifespan.
OUTLINE DRAWING
CONSTRUCTION:
CORE
The core is crafted from cold-rolled grain-oriented (CRGO) silicon steel, cut to precise dimensions via automated machines, ensuring minimal air gaps, low exciting current, and reduced noise. Each lamination is insulated, guaranteeing a long, trouble-free core life. The 45° stepping lamination technique effectively reduces no-load current.
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
The LV winding is crafted with high-quality foil conductor or copper wire, offering balanceable ampere-turns. This reduces additional loss and enhances short-circuit resistance. Scientifically designed oil drawings optimize heat dispersion, increasing heat dissipation surface area, thereby reducing temperature and improving overload capability.
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 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.
