Customized Oil-Immersed Power Distribution Transformer
Our Oil Immersed Transformer series is characterized by low noise, minimal loss, and low partial discharge. These transformers feature a rational structure, top-quality materials, scientific design, meticulous craftsmanship, and advanced testing methods. Here are the standout characteristics of this series:
Exceptional dynamic thermal stability, superior short-circuit resistance, high lightning impulse resistance, and high reliability.
Low loss, energy-efficient, economical operation, and maintenance-free.
Artistic contour, compact size, low installation, and maintenance costs.
Performance and parameters conform to or exceed the standards of IEC.
Fully hermetically sealed oil tank, effectively preventing air from eroding the oil, thus prolonging the transformer’s service life.

CONSTRUCTION:
CORE
The core is crafted from cold-rolled grain-oriented (CRGO) silicon steel, cut to precise dimensions using automated machines to reduce air gaps, minimize exciting current, and lower noise. Each lamination is insulated, ensuring a long, trouble-free service life. The use of a 45° stepping all-leaning lamination method efficiently 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
LV windings are crafted with high-quality foil conductors or copper wire, ensuring balanced ampere-turns. This reduces additional loss and enhances short-circuit resistance. Heat dissipation is scientifically managed in the windings, increasing the heat dissipation surface area, reducing temperature, and improving overload capacity.
temperature is reduced and the ability of over-load is improved.
HV windings are manufactured with high-quality copper wire and an excellent design structure, improving the electric field distribution. 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.
