Selection notes

How to read this family

SC(B)18 is the ultra-low-loss end of the cast-resin range. It is selected when the project has a strict energy target, a high load factor or a long service life, and the higher first cost can be recovered through lower losses.

The family covers 100 to 2,500 kVA at 10, 20 and 35 kV. The design combines a high-grade core, optimised winding geometry and a rigid cast-resin structure. Low noise and low partial discharge make it suitable for hospitals, laboratories, data centres and premium commercial buildings.

Because the loss difference is small in absolute terms at low ratings, the economic case is strongest for units that run for many hours at medium-to-high load. A life-cycle cost calculation should be completed before the specification is fixed.

Buyer questions

Questions to settle before the datasheet

When does SC(B)18 make economic sense?
When the transformer runs for many hours at medium or high load and electricity is expensive. The lower losses compound over the service life; a life-cycle cost calculation shows the payback.
Is SC(B)18 available at 35 kV?
Yes, subject to the rating and insulation design. The 35 kV version has different clearances and test requirements from the 10 kV version.
What noise level can be guaranteed?
Sound level depends on rating, core grade and enclosure. A guaranteed value at a stated measurement distance should be written into the datasheet.
