OUTLINE DRAWING
CONSTRUCTION:
CORE
Our core is crafted from cold-rolled grain-oriented (CRGO) silicon steel. Automated machines cut the steel sheets into precise dimensions, reducing air gaps, exciting current, and noise. Each lamination is insulated to ensure a long, trouble-free lifespan. Using a 45° stepping and all-leaning lamination technique, no-load currents are efficiently minimized.
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
Our LV winding is made with high-quality foil conductor or copper wire, ensuring balanced ampere-turn and low additional loss. This design enhances short-circuit resistance. Heat dispersion is scientifically managed in the winding, increasing heat dissipation and reducing temperature, thereby improving overload capacity.
temperature is reduced and the ability of over-load is improved.
The high-voltage winding is meticulously crafted with premium copper wire, boasting an exemplary design structure. This advancement enhances the electric field distribution and efficiency. With the integration of advanced lighting
impulse analysis, the transformer's ability to withstand lightning impulses has significantly increased.
TANK
Crafted from high-quality steel, the tank’s surface undergoes a robust rust-elimination process, followed by a phosphate coating and an application of FVC anticorrosive paint. It’s engineered to
resist corrosion from oil and chemicals, making it ideal for harsh outdoor environments. Its artistic contour ensures easy
installation and maintenance-free operation.
INSULATION OIL L
Our insulating oil is PCB-free and complies with the stringent standards of IEC60296, ensuring top-notch performance and safety.

Process Technology:
Core:
The transformer's core is constructed from high-quality, cold-rolled, grain-oriented silicon steel sheets with superior magnetic permeability. Utilizing a full 45° slope lamination approach, we substantially reduce no-load loss and no-load current.
Through Simulating Analysis in the core model design, we accurately determine the frequency and size of vibrations, effectively preventing core cavity resonance.
A spring connection between the core, windings, and frame results in noise levels that are 10 to 15dB lower than standard.
