CATALOGUE REFERENCE SC(B)12 / SC(B)14 / SC(B)18

This Daqo series covers indoor 20 kV dry-type applications. The source lists 20/0.4 kV and 20/10 kV configurations with different capacity ranges. Confirm the selected configuration rather than assuming all options can be combined.

Series capacity: 30–25,000 kVA
No-load loss: Not documented
Primary voltage: 20 kV
Evidence status: Manufacturer-published
