Customized Oil-Immersed Power Distribution Transformer
The Oil Immersed Transformer series features low noise, low loss, and minimal partial discharge. Incorporating a rational structure, high-quality materials, scientific design, meticulous craftsmanship, and advanced testing methods, the series boasts:
Exceptional dynamic thermal stability, superior short-circuit resistance, high lightning impulse resistance, and unparalleled reliability.
Energy efficiency, economic operation, and maintenance-free performance.
Aesthetic contour, compact size, and low installation and maintenance costs.
Performance and parameters are compliant with or exceed IEC standards.
A fully hermetically sealed oil tank effectively prevents oil erosion by air, extending the transformer's service life.
OUTLINE DRAWING
CONSTRUCTION:
CORE
The core is crafted from cold-rolled grain-oriented (CRGO) silicon steel, cut to precise dimensions via automated machines to ensure reduced air gaps, low excitation current, and minimal noise. Each lamination is insulated to guarantee a prolonged trouble-free lifespan. The 45° stepping and leaning lamination technique significantly reduces no-load current.
WINDINGS
The LV winding, made of high-quality foil conductor or copper wire, ensures balanced ampere-turns, resulting in low additional loss and enhanced anti-short capabilities. Scientifically designed oil channels for heat dispersion increase the heat dissipation surface, lowering temperature and boosting overload capacity.
The HV winding is constructed with premium copper wire and an exceptional design structure that optimizes electric field distribution. Enhanced to withstand 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.
