⚠ Note: 1. For on-load tap-changing SCZ(B)10 series transformers, only the following data are adjusted: weight increases by 100kg, dimension 'a' increases by 650mm, and dimension 'b' increases by 750mm due to the on-load switch arrangement on the side of the transformer.
2. The high voltage side of on-load tap-changing transformers can provide a tapping range of 4×2.5%.
3. The weight and overall dimension data in the table are for reference only; changes may be made without prior notice.

Frequently Asked Questions

QWhat does SC(B)10 stand for in the transformer designation?

The designation SC(B)10 represents: S = Three-phase, C = Resin Cast, B = Insulated Winding (foil-wound), 10 = Performance Level Code. The following numbers indicate rated capacity (kVA) and voltage class (kV) respectively.

QWhat is the available capacity range for the SC(B)10 dry-type transformer?

The SC(B)10 series is available from 30 kVA up to 2500 kVA (and up to 4000 kVA upon request). This wide range makes it suitable for commercial buildings, industrial facilities, and utility substations.

QWhat primary (high) voltage options are supported?

The SC(B)10 transformer supports primary voltages of 6 kV, 6.3 kV, 6.6 kV, 10 kV, 10.5 kV, and 11 kV. The primary voltage can also be extended up to 35 kV for special applications.

QWhat is the tapping range and how is it adjusted?

Standard off-load tap-changers provide ±5% or ±2×2.5% tapping range. For on-load tap-changing (SCZ(B)10 series), a 4×2.5% tapping range is available on the high voltage side, allowing voltage adjustment without de-energizing the transformer.

QWhat are the applicable standards and vector group options?

The SC(B)10 transformer complies with IEC 60076. Supported vector groups include Yyn0 and Dyn11 for standard configurations, and Dyn5 is also available. These options accommodate various grounding and phase shift requirements in power distribution systems.

QWhat are the advantages of epoxy resin cast dry-type transformers over oil-immersed types?

Epoxy resin cast dry-type transformers like the SC(B)10 offer several advantages: they are fire-resistant and environmentally friendly (no oil leakage risk), require minimal maintenance, have excellent moisture and humidity resistance, and are safe for installation in populated or enclosed areas such as commercial buildings, hospitals, and underground substations.
