Frequently Asked Questions (FAQ)

What do the model designations SCB11-RL and SCB13-RL stand for?

"SCB" designates a resin-cast dry-type transformer. The numbers "11" and "13" represent the performance level generation codes (with 13 being more energy-efficient), and "RL" refers to the three-dimensional triangular core structure.

What are the primary advantages of a three-dimensional triangle core design?

The three-dimensional triangular core structure provides a balanced three-phase magnetic circuit, which significantly reduces no-load loss, no-load current, and operational noise levels compared to traditional planar cores.

What voltage combinations are supported by these dry-type transformers?

They support high-voltage ratings of 6kV, 6.3kV, 6.6kV, 10kV, 10.5kV, or 11kV (with demarcation ranges of ±5% or ±2×2.5%) and a standard low-voltage output of 0.4kV.

How does temperature class affect the load loss group values?

Load losses are calculated based on the reference insulation system temperatures. The tables outline load loss limits for Class B (100°C), Class F (120°C), and Class H (145°C) to match diverse operational environments.

Why might the actual dimensions and weights differ from the product tables?

As products undergo continuous technological optimization and structural updates, physical dimensions and weight figures are subject to minor adjustments. It is recommended to confirm final drawings when placing an order.

What is the standard connection group label for these models?

The standard connection group configuration is Dyn11, which offers superior performance in mitigating harmonic currents and handling unbalanced loads.
