CONSTRUCTION:

CORE

The core is manufactured from cold-rolled grain oriented, (CRGO) silicon steel. The steel sheets are cut into required dimensions on automated
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 winding is manufactured with high quality foil conductor or copper wire, and the ampere-turn is balanceable. The additional loss is low and the ability of anti-short is improved. Oil drawings of heat dispersion are scientifically used in the winding, and the surface of heat dissipation is increased, so the temperature is reduced and the ability of over-load is improved.
temperature is reduced and the ability of over-load is improved.
HV winding is manufactured with high quality copper wire and excellent design structure. It improves the distribution of electric field. With lighting
Through extensive research and meticulous impulse analysis, we have significantly bolstered the transformer's resistance to lightning-induced surges, ensuring unparalleled protection and reliability.

TANK

Constructed from premium, high-quality steel, our tank undergoes rigorous rust elimination and phosphate coating processes. It is then meticulously finished with FVC anticorrosive paint, ensuring long-lasting durability.
This robust construction not only offers exceptional resistance to oil and chemical corrosion but also features a visually appealing design, making it ideal for harsh outdoor environments.
Our transformer guarantees easy installation and is virtually maintenance-free, saving time and reducing operational costs.
