20kV Dry Type Distribution Transformers We Manufacture
SCB series epoxy resin cast transformers from 20 kV to 35 kV class, 30 kVA to 6300 kVA, with F/H class insulation and full factory testing.
What Is a 20kV Dry Type Distribution Transformer?
A 20kV dry type distribution transformer steps 20 kV primary distribution voltage down to utilisation voltage using cast-resin or open-wound dry-type construction. It brings the fire safety and low maintenance of dry-type technology to medium voltage distribution.
20 kV networks are standard in many European and Asian distribution systems, feeding commercial centres, industrial zones and public infrastructure where oil-filled units are not permitted or desirable.
- 20-35 kV class – SCB cast-resin units for medium voltage distribution.
- Fire-safe construction – no oil – safe for indoor and urban installations.
- Low maintenance – no oil sampling or containment; minimal routine care.
- 50,000m²工場 – in-house winding, casting, curing and testing.
- 350人以上の従業員 – engineering and export teams supporting every order.
- OEM / ODM & 卸売 – private labelling, packaging and volume pricing.
Main Types of Medium Voltage Dry Type Transformers
We manufacture two construction types at 20 kV:
SCB epoxy resin cast
Vacuum-cast windings for indoor medium voltage substations.
Open-wound / ventilated
Air-insulated construction for lower cost applications with adequate ventilation.

20kV Dry Type vs Oil Immersed for Medium Voltage Distribution
Oil-immersed units are cheaper per kVA and suit outdoor substations, but need oil containment and fire protection. Dry-type units cost more upfront but eliminate fire risk, reduce building requirements and suit indoor, urban and high-value installations.
The choice comes down to site and application – our engineers confirm the right technology on drawings before production.
Choosing a 20kV Dry Type Distribution Transformer Manufacturer
At medium voltage, partial discharge performance and thermal design separate good manufacturers from the rest. Verify type test reports, process control and reference deliveries.
Subian Electric brings a 50,000m² factory, 350+ employees, ISO9001, CE and UL certification and export to 50+ countries with in-house vacuum casting.
Send your voltage, capacity and application – we confirm the design and price before production.
認証 & 品質保証
Our 20kV dry-type transformers are produced under ISO9001, ISO14001 and ISO45001 management systems, with CE and UL certification and type test reports.
