Dry-Type Transformer Model Number Guide & Selection Handbook 

1. Dry-Type Transformer Model Number Decoding

Example Model: SCB13-1000/10

• SC: Three-phase epoxy resin cast dry-type transformer
• B: Foil winding (“R” indicates wire-wound)
• 13: Performance level code (higher number = better efficiency)
• 1000: Rated capacity 1000kVA
• 10: High voltage side 10kV

Common Prefix Meanings:

2. Performance Comparison of Mainstream Models

3. Recommended Models by Application

Data Centers

• Preferred: SCB12/SCB14 series
• Advantages: Low loss (Tier1 efficiency), K-13 harmonic resistance
• Case study: Tencent Tianjin Data Center uses 6× SCB14-2500 units

Hospitals/Schools

• Requirement: SCB13-Class H (fire safety certified)
• Special: IP54 protection + ultra-quiet (<55dB)

Solar/Wind Power

• Dedicated model: SCR12-35/0.8
• Features: 35kV input + reverse power protection

4. Model Upgrade Solutions

Legacy Model Replacement

• SCB9 → SCB12 (saves ~18% annual electricity cost)
• SGB10 → SGB11 (5dB noise reduction)

Capacity Expansion
For SCB10-800 with 20% load growth:

• Option 1: Upgrade to SCB12-1000
• Option 2: Parallel connect SCB10-200 (more economical)

5. Procurement Guidelines

⚠ Fake Product Identification:

• Genuine products: Laser anti-counterfeit code + verifiable on official website
• Low-price traps: Aluminum windings disguised as copper (request material certification)

✅ Warranty Essentials:

• Core components ≥10-year warranty (written confirmation required)
• Free technical support within 200km radius

6. 2024 New Model Preview
