Customized Oil-Immersed Power Distribution Transformer
Our Oil Immersed Transformer series is renowned for its low noise, minimal energy loss, and reduced partial discharge. Featuring a rational structure, high-quality materials, scientific design, precise craftsmanship, and advanced testing methods, this series boasts the following characteristics:
Exceptional dynamic thermal stability, superior short-circuit resistance, high lightning impulse resistance, and unparalleled reliability.
Energy-efficient with low loss, these transformers operate economically and are maintenance-free.
Artistic contour, compact size, and minimal installation and maintenance costs.
The performance and parameters conform to or exceed IEC standards.
Fully hermetically sealed oil tank prevents air from eroding the oil, thereby extending the transformer's service life.
OUTLINE DRAWING
CONSTRUCTION:
CORE
Our core is crafted from cold-rolled grain-oriented (CRGO) silicon steel, cut to precise dimensions with automated machines, ensuring reduced air gap, low exciting current, and low noise. Each lamination is insulated to ensure a long, trouble-free life. Using a 45° stepping all leaning lamination method, we significantly reduce the 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 constructed with high-quality foil conductor or copper wire, ensuring balanceable ampere-turn and reduced additional loss. Scientifically designed oil drawings enhance heat dispersion, increase the heat dissipation surface, reduce temperature, and improve overload capacity.
The temperature is reduced, enhancing the ability to handle overload conditions.
The HV winding is made with premium copper wire and an excellent design structure, improving electric field distribution. Featuring robust 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.
