CONSTRUCTION:
CORE
The core is manufactured from cold-rolled grain-oriented (CRGO) silicon steel. The steel sheets are cut into required dimensions using automated
machines, ensuring reduced air gap, low exciting current, and low noise. Each lamination is insulated from one another to guarantee a long, trouble-free lifespan. The 45° stepping and all-leaning lamination method helps efficiently reduce no-load current.
WINDINGS
The LV winding is crafted using high-quality foil conductor or copper wire, ensuring a balanced ampere-turn. This design minimizes additional loss and enhances short-circuit resistance. Scientific heat dispersion techniques are incorporated in the winding to increase the heat dissipation surface, reducing temperature and improving overload capacity.
temperature is reduced and the ability of over-load is improved.
The high voltage (HV) winding of the S11-250kVA Oil Immersed Power Transformer is meticulously crafted with premium copper wire and an exceptional design structure. This innovation significantly enhances the electric field distribution, ensuring superior performance. With our state-of-the-art lighting impulse analysis, the transformer's resilience against lightning impulses is remarkably improved.
Our advanced lighting impulse analysis further fortifies the transformer's resilience against lightning impulses, ensuring enhanced protection and durability.
TANK
Constructed from high-quality steel, our tank exhibits superior craftsmanship. The surface undergoes a rigorous rust elimination process followed by a phosphate coating and is finished with FVC anticorrosive paint. This ensures remarkable resistance to oil and chemical corrosion, making it ideal for outdoor applications in harsh environments. Its artistic contour enhances aesthetic appeal, while its design facilitates easy installation and maintenance.
With its exceptional resistance to oil and chemical corrosion, the tank is perfectly suited for challenging outdoor conditions. Its elegant design not only adds to its aesthetic appeal but also ensures ease of installation and maintenance-free operation.
Designed for outdoor settings, the tank's artistic contours and maintenance-free operation make it an optimal choice for harsh environments.

Process Technology:
Core:
Crafted from high-quality, cold-rolled, grain-oriented silicon steel sheets, our transformer's core boasts exceptional magnetic permeability. The innovative 45° slope lamination technique significantly reduces both no-load loss and no-load current, ensuring unparalleled efficiency.
Utilizing advanced Simulating Analysis in core model design, we precisely calculate vibration frequencies and dimensions to prevent core cavity resonance, enhancing stability and performance.
The spring connection between the core and windings, as well as between the core and frame, ensures that our transformer's noise levels are 10 to 15dB lower than standard, providing a quieter operation.
