Product features：

1. Low loss and significant energy saving. Especially, the no-load loss has been significantly reduced, with an average reduction of about 25% compared to the national standard GB/T6451-2008;

2. The iron core is made of high-quality cold-rolled silicon steel sheets, with advanced domestic cross cutting lines, shear burrs less than 0.02mm, fully inclined seams, non punching, and non overlapping iron yoke technology; The iron core columns are stacked with double H adhesive, making the three pillars and two yokes of the iron core a tight, flat, and compact whole, effectively reducing the no-load loss, no-load current, and noise of the transformer;

3. The transformer coil uses high-purity oxygen free copper, effectively reducing copper consumption. The coil pad and support bar are rounded to ensure even electric field and increased reliability. The internal winding support is strengthened to improve its stability and prevent unstable deformation. For products with a capacity of over 16000KVA, the inner and outer coils are assembled using a unified integral support plate and pressure plate to simultaneously back pressure each coil, ensuring consistency in the height and size of each coil in the axial direction, and improving the transformer's ability to withstand sudden short circuits;

4. The plate clamp and side beam form a sturdy frame structure, and the body and fuel tank are rigidly positioned on six sides, allowing the body to withstand various transportation conditions without displacement. If the impact during product transportation is less than the specified value, it can be directly tested and put into operation on site without undergoing suspension inspection, reducing a lot of on-site suspension work for the product;

5. The wall of the fuel tank is made of integral steel plate, which is folded and pressed into a corrugated structure by a large press, reducing welding seams, increasing mechanical strength, expanding the heating area, and improving heat dissipation efficiency. At the same time, the corrugated box wall avoids the reflection of sound waves on the plane and reduces noise. The overall appearance and simplicity of the transformer;

6. The use of capsule type oil storage tanks effectively slows down the aging degree of transformer oil; The pointer type oil level gauge can avoid the occurrence of false oil level and solve the problem of transformer oil aging under light exposure; Gas relay with gas collection device for easy maintenance and operation;

7. For traditional sealing structures, especially those prone to oil leakage, starting from material procurement control, ensuring that the steel is not rusted, bumped, scratched, or hammered, special processing is carried out on the sealing part of the oil tank, and the entire box body is painted to remove sharp edges, burrs, and welding slag generated during processing inside the box, and to enhance the adhesion of the paint.
