Overview of the SCBH Series 10kV Amorphous Alloy Dry-Type Transformer
The SCBH series amorphous alloy dry-type transformer is a high-efficiency 10kV distribution solution built around an amorphous metal core — a material that exhibits significantly lower hysteresis losses than conventional silicon steel. In SCBH15, SCBH17, and SCBH19 models, this core technology reduces no-load losses by up to 70% compared to traditional dry-type units, earning IE3/IE4 efficiency compliance and delivering substantial long-term energy savings.
Encapsulated in fire-resistant epoxy resin (Class F/H insulation), the transformer is inherently flame-retardant and explosion-proof, meeting IEC 60076-11 for safety. Natural air cooling (AN) is supplemented by an optional forced-air fan system controlled by PT100 sensors, while an RS485 interface enables remote temperature monitoring and alarm integration. This amorphous core transformer is purpose-built for harsh environments — humid, dusty, or coastal — and delivers reliable, low-maintenance operation with noise levels below 65dB.
- Rated 10kV primary, 0.4kV secondary, with ±2×2.5% or ±5% tapping range.
- Power ratings from 30kVA to 2500kVA, short-circuit resistance ≤25kA/2s.
- Insulation class F/H, temperature rise ≤100K/125K.

Frequently Asked Questions
What is the purpose of a dry type transformer?
A dry type transformer provides voltage transformation without flammable insulating liquids. Its solid epoxy resin insulation eliminates fire risk and oil leaks, making it the preferred choice for indoor, commercial, and safety-sensitive installations.
How many amps is a 10 kVA transformer?
For a three-phase 400V system, a 10 kVA transformer delivers about 14.4A. Our SCBH series starts at 30kVA up to 2500kVA, covering a wide range of medium-voltage distribution needs at far higher amperages.
What is the maximum voltage for a dry type transformer?
Dry-type transformers are commonly manufactured up to 36kV or higher; our SCBH series is rated for 10kV primary with insulation impulse withstand up to 75kV, and we can customize for 20-35kV as required.
What is a 10 mVA transformer?
A 10 MVA (10,000 kVA) transformer has the capacity to deliver 10 megavolt-amperes of apparent power. It is typically used in primary substations or large industrial plants. Our SCBH range extends to 2500kVA for medium-voltage distribution; contact us for higher-capacity custom designs.
