Customized Oil-Immersed Power Distribution Transformer
Our Oil Immersed Transformer series is renowned for its low noise, minimal loss, and low partial discharge. Utilizing a rational structure, high-quality materials, scientific design, meticulous craftsmanship, and advanced testing methods, these transformers offer the following superior characteristics:
Exceptional dynamic thermal stability, outstanding short-circuit resistance, and high lightning impulse resistance, ensuring high reliability.
Energy-efficient with low loss, they run economically and are maintenance-free.
Artistic contour, compact size, and low installation and maintenance costs.
Performance and parameters that meet or exceed IEC standards.
Fully hermetically sealed oil tanks, 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. Automated machines cut the steel sheets into precise dimensions, ensuring reduced air gaps, low exciting current, and minimal noise. Each lamination is insulated, ensuring a long, trouble-free lifespan for the core. Our 45° stepping and all-leaning lamination technique 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
The LV winding is made from high-quality foil conductor or copper wire, ensuring a balanced ampere-turn. This design lowers additional loss and enhances anti-short capabilities. Scientifically designed oil drawings for heat dispersion increase the heat dissipation surface, reducing temperature and enhancing overload capacity.
temperature is reduced and the ability of over-load is improved.
Our HV winding is meticulously crafted using premium quality copper wire and an outstanding design structure, enhancing the distribution of the electric field. Equipped with state-of-the-art lighting impulse analysis, our transformers boast improved resilience against lightning impulses.
With lightning impulse analysis, the ability of anti-lighting impulse has been significantly enhanced.
TANK
Crafted from top-tier steel, our tank is meticulously jointed and treated with a rust-phosphate coating, followed by an application of FVC anticorrosive paint. This ensures remarkable durability and protection against oil and chemical corrosion.
Our tank's superior design efficiently prevents corrosion from oil and chemical substances. Its artistic contour and ease of installation make it ideal for harsh outdoor environments, requiring minimal maintenance.
The design ensures effortless installation and maintenance-free operation in the most challenging environments.
INSULATION OIL L
Our inhibiting insulation oil is free from PCB and adheres to the stringent IEC60296 standards, ensuring top-notch performance and safety.

Process Technology:
Core:
Our transformer cores are constructed using high-quality, cold-rolled, grain-oriented silicon steel sheets with superior magnetic permeability. Utilizing full 45° slope lamination, we significantly reduce no-load loss and no-load current.
By employing Simulating Analysis in core model design, we precisely calculate the frequency and size of vibrations, effectively preventing core cavity resonance.
We utilize spring connections between the core & windings and the core & frame, resulting in noise levels that are 10 to 15dB lower than the standard.
