Customized Oil-Immersed Power Distribution Transformer
The Oil Immersed Transformer series stands out with low noise, low loss, and minimal partial discharge. Featuring a rational structure, high-quality materials, scientific design, strict craftsmanship, and advanced testing methods, these transformers boast the following characteristics:
Exceptional dynamic thermal stability, outstanding short-circuit resistance, high lightning impulse resistance, and high reliability.
Low loss, energy conservation, economic operation, and maintenance-free performance.
Aesthetic contour, compact size, and low installation and maintenance costs.
Performance and parameters that meet or surpass IEC standards.
Fully hermetically sealed oil tank, effectively preventing air from eroding the oil and extending the transformer's service life.
OUTLINE DRAWING
CONSTRUCTION:
CORE
The core is crafted from cold-rolled grain-oriented (CRGO) silicon steel. Each steel sheet is precision cut on automated
machines, ensuring reduced air gaps, low exciting current, and low noise. Each lamination is insulated to guarantee the core's long, trouble-free lifetime. Using a 45° stepping lamination technique, no-load currents are efficiently minimized.
WINDINGS
The LV winding, made from high-quality foil conductor or copper wire, ensures balanced ampere-turns, reduced additional loss, and improved short-circuit resistance. Heat dispersion in the winding is scientifically optimized, increasing heat dissipation and reducing temperature, thereby enhancing overload capacity.
Heat dissipation increases, temperature decreases, and overload capacity improves.
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.
