Advantages

1. Optimization of magnetic circuit

No joints between core layers ensures uniform magnetic circuit distribution and no high resistance areas.
Magnetic flux direction is consistent with silicon steel sheet orientation.
Three-phase magnetic circuit is symmetrical, balanced, and the shortest possible length.

2. Low loss, energy savings remarkable

Iron loss reduced by 10-20% compared to laminated cores due to the 3D wound structure.
Core yoke material usage is reduced by 25%.
High-temperature nitrogen vacuum annealing eliminates mechanical stress and improves magnetic performance.
No-load loss is 25-35% lower than national standards.

3. Low noise

Seamless continuous rolling eliminates vibration noise common in laminated cores.
Symmetrical magnetic flux and reasonable magnetic density design significantly reduce product noise.

4. High overload ability

Very low heat generation due to minimal no-load loss and current.
Delta-shaped three-phase coil creates a "chimney effect" for superior cross-ventilation and heat radiation.

5. Compact structure, small location

Body footprint is 10-15% smaller and height is 10-20% lower than traditional products, saving space in substation boxes.

6. Anti-theft

The copper coil is wounded onto the iron core, making it extremely difficult to remove without professional heavy equipment.

Frequently Asked Questions

Q1: What is the main difference between S11 and S13 transformers?

The S13 series offers significantly lower no-load losses compared to S11, leading to higher energy efficiency and lower operational costs in the long run.

Q2: Why is the 3D triangular wound core quieter than traditional designs?

Because the core is made from continuous silicon steel strips without seams or joints, it eliminates the electromagnetic vibration and noise typically found in laminated core seams.

Q3: How does the "Anti-theft" feature work?

In a 3D wound core design, the copper coils are tightly integrated with the core structure. Removing the copper for its scrap value is nearly impossible without using large-scale industrial machinery.

Q4: Is this transformer suitable for residential areas?

Yes, its ultra-low noise design and compact footprint make it ideal for urban residential power distribution where space is limited and noise regulations are strict.

Q5: Does the 3D structure improve the lifespan of the transformer?

Yes, the symmetrical magnetic circuit and superior "chimney effect" heat dissipation reduce thermal stress on the insulation, potentially extending the service life of the unit.

Q6: Can it handle fluctuations from renewable energy sources?

Absolutely. Its stable voltage regulation and high overload capacity make it an excellent choice for integrating solar and wind energy into the power grid.
