Dry-type transformers
SCB10 / SCB11 / SCB13 Cast-Resin Dry-Type Transformer
Fire-safe, oil-free power for buildings, hospitals and factories.
- 30–2,500 kVA
- 6–11 / 0.4 kV
- IEC 60076-11
Epoxy cast-resin dry-type transformers from 30 to 2,500 kVA for 6–11 kV supplies. No oil, self-extinguishing and maintenance-free — the standard choice for indoor substations, high-rise buildings, airports, metros and process plants. Optional IP20/IP23 enclosures and fans for +20% output.
