Product Overview – Built for Indoor & Fire-Safe Operation
This three-phase, dry-type (cast resin), 50/60Hz distribution transformer steps down 10kV primary voltage to 0.4kV (400V) secondary voltage. It is the standard choice for:
-
Industrial plants (manufacturing, textile, chemical)
-
Commercial buildings & shopping malls
-
Hospitals & data centers
-
High-rise residential & office buildings
-
Schools, hotels, airports
Available in SCB10, SCB11, SCB12, SCB13, SCB14 and other energy‑efficient series, fully compliant with IEC 60076, GB/T 10228, ANSI/IEEE standards.
Key Features That Resonate with B2B Buyers
✅ Low Loss & Energy Efficient – Lower OPEX
High-grade grain-oriented silicon steel core + optimized coil design significantly reduces no-load and load losses. Your electricity bill drops.
✅ Cast Resin Encapsulation – Fire Safe & Maintenance-Free
HV windings fully encapsulated in epoxy resin. Self-extinguishing, no partial discharge, moisture-proof, pollution-proof. No periodic cleaning or testing required.
✅ Strong Short-Circuit Withstand – Less Downtime
Rigid coil structure + uniform ampere-turn distribution. Proven to survive grid faults without internal damage.
✅ Low Noise & Low Partial Discharge – Suitable for Noise-Sensitive Environments
Advanced manufacturing process ensures noise level well below standard limits. Ideal for hospitals, schools, hotels, and residential areas.
✅ Optional Protection Enclosure – IP20, IP23, IP34
Open type (IP00) or optional enclosure for additional safety, dust protection, and water ingress prevention.

Common Customer Questions (We Answer Fast)
Q: Can you supply 80 units within 20 days?
A: Yes – our monthly capacity exceeds 400 units. We regularly fulfill large‑batch orders without delaying other customers.
Q: What is the difference between SCB10, SCB11, SCB12, SCB13, SCB14?
A: Higher numbers indicate lower losses and higher efficiency. SCB14 meets the highest Tier 1 energy efficiency standards. We can recommend based on your local energy policy and payback requirements.
Q: Do I need an enclosure?
A: For indoor installation without public access, IP00 is sufficient. For areas with dust, moisture, or accidental contact risk, we recommend IP20/IP23.
Q: Do you provide test reports before shipment?
A: Absolutely. Routine tests (IEC/ANSI) are included. Type tests or witnessed tests available upon request.
