2

Premium projects

Ideal for green-building and high-efficiency certification requirements.

3

Maintenance

No oil handling - periodic cleaning and inspection only.

- Frequently Asked Questions

What makes SCB15 different?

SCB15 offers the highest efficiency level among cast-resin dry-type transformers, minimizing lifetime operating cost.

Where should I use SCB15?

Projects with high energy costs or strict efficiency requirements, such as green buildings and premium commercial facilities.

Does it need special maintenance?

No oil changes or leak management — periodic cleaning and inspection are sufficient.

Derived Ratings (calculated from the configuration)

The values below are computed from what you selected above. Anything that cannot be computed yet is shown as an em dash — never as zero.

Iₙ = S / (√3·U) · I_sc = 100·Iₙ / uₖ · S_sc = √3·U·I_sc · I_p = k·Iₖ

Inputs taken from the configuration

Rated current Iₙ—
Short-circuit current I_sc—
Short-circuit current I_sc—
Short-circuit power S_sc—
I_sc is calculated on the transformer impedance basis alone (system impedance neglected) — the same basis used in IEC 60076-5 short-circuit calculations.
System voltage → —

Still required to complete the calculation: rated capacity S, impedance voltage uₖ, short-time or peak withstand current.

Per-model values (P0 / Pk / uₖ declared by the factory, losses, noise, temperature rise, dimensions, weight) are not in the product library: those rows stay at an em dash until the factory parameter sheet is supplied. An em dash means the value is unavailable — it is never rendered as zero.

Derived losses (from the selected efficiency grade + capacity)
Class 2 (SCB13)
No-load loss P0 (kW)—
Load loss Pk (kW)—

Read-only: no price factor, not part of the sum — the loss-grade cost is already carried by the efficiency (subtype) base price, so charging here would double-bill. Values come from the product library type-test data, interpolated between published capacities; grades the library does not cover show an em dash, never zero.
