Product Overview
The SC(B)11 is a three-phase cast-resin dry-type power transformer with Class F insulation. The listed technical range covers 30 to 2,500 kVA, with 6, 6.3 and 10 kV high-voltage options and a 0.4 kV low-voltage rating.
Construction and Features
- Epoxy-resin cast insulation for dry-type construction.
- Class F insulation, as specified for this series.
- Standard open construction without an enclosure, with IP00 protection.
- IP20 and IP23 enclosures available on request; confirm the material and final dimensions.
- Designed for distribution applications where the selected installation requires dry-type equipment.

The 1,000 kVA entry lists a no-load loss of 1,770 W and a load loss of 8,130 W.
Loss values follow the product catalogue schedule. Confirm the reference temperature, voltage configuration and guaranteed losses in the approved technical schedule before comparing series or placing an order.
Selection and Enquiries
Send the required rated capacity, primary and secondary voltages, frequency, connection, installation conditions, enclosure requirements, quantity and project location. Request the confirmed dimensions, weight, sound-level data, short-circuit impedance and scope of supply for the selected unit.
Installation and Maintenance
Installation, ventilation, fire-safety provisions and any hazardous-area requirements must be assessed for the selected design and site. Dry-type construction does not by itself establish an explosion-protection rating. Follow the manufacturer’s installation, inspection and maintenance instructions.
