Frequently Asked Questions (FAQ)

What is a three-dimensional triangle core dry-type power transformer?

It is a modern dry-type power transformer utilizing a three-dimensional triangular wound core structure. This design optimizes the magnetic circuit, lowers no-load loss, reduces noise levels, and enhances mechanical strength compared to traditional laminated core transformers.

What do the model designations SCB11 and SCB13 indicate?

The model designations represent different design sequences and loss levels. "S" stands for three-phase, "C" indicates cast resin insulation, "B" represents foil winding, and the numbers "11" and "13" denote performance levels where higher numbers typically align with lower load losses and better overall energy efficiency.

Why does the connection group label Dyn11 matter?

Dyn11 is a vector group designation where the high-voltage winding is Delta connected (D), the low-voltage winding is Star connected (y) with a neutral point (n), and the phase displacement is 30 degrees lagging (11). This connection is ideal for unbalanced loads and helps suppress harmonic currents in the power grid.

How does temperature class (B, F, H) affect load loss values?

As the insulation class temperature increases (from Class B at 100°C to Class F at 120°C and Class H at 145°C), the resistance of the windings increases, which results in slightly higher load loss values. The tables outline these specific load losses to help engineers calculate real-world operating efficiencies.

Are the dimensions and weights in the specification tables fixed?

No. Due to continuous product upgrades and design optimization, physical dimensions and total weights are subject to change. It is recommended to confirm final dimensions with the manufacturer during the ordering process.
