Customized Oil-Immersed Power Distribution Transformer
The Oil Immersed Transformer series is renowned for its low noise, low loss, and low partial discharge. With a rational structure, premium materials, scientific design, meticulous craftsmanship, and advanced testing methods, this series boasts the following features:
Exceptional dynamic thermal stability, excellent short-circuit resistance, superior lighting impulse resistance, and high reliability.
Low loss, energy conservation, economical performance, and maintenance-free operation.
Aesthetically pleasing contour, compact size, and low installation and maintenance costs.
Performance and parameters meet or exceed the standards set by IEC.
A fully hermetically sealed oil tank effectively prevents air from contaminating the oil, thereby extending 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, ensuring reduced air gaps, low exciting currents, and minimal noise. Each lamination is insulated to guarantee a long, trouble-free core life. Utilizing a 45° stepping lamination method, we efficiently reduce no-load currents.
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 manufactured with high-quality foil conductor or copper wire, ensuring balanced ampere-turns. This results in low additional loss and improved short-circuit resistance. Scientifically designed oil drawings enhance heat dissipation, reduce temperature, and improve overload capacity.
temperature is reduced and the ability of over-load is improved.
The HV winding, made from high-quality copper wire and an excellent design structure, enhances electric field distribution.
Through advanced impulse analysis, the transformer's anti-lightning impulse capability has been significantly enhanced.
TANK
The tank is crafted from premium high-quality steel. Its surface undergoes a meticulous rust elimination process, phosphate coating, and is painted with resilient FVC anticorrosive paint. The result is a tank that
boasts exceptional resistance to oil and chemical corrosion. Its aesthetically pleasing contour and robust design make it ideal for harsh outdoor environments, offering easy
installation and virtually maintenance-free operation.
INSULATION OIL L
Our insulation oil is PCB-free, inhibited, and fully compliant with IEC60296 standards.

Process Technology:
Core:
Our transformer core is meticulously constructed from high-quality cold-rolled grain-oriented silicon steel sheets with superior magnetic permeability. Utilizing full 45° slope lamination, the no-load loss and no-load current are remarkably reduced.
Employing Simulating Analysis in core model design enables precise calculation of vibration frequency and magnitude, thus avoiding core cavity resonance.
Spring connections between the core and windings, and core and frame, result in noise levels that are 10 to 15 dB lower than standard.
