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 factory – in-house winding, casting, curing and testing.
- 350+ employees – engineering and export teams supporting every order.
- OEM / ODM & wholesale – 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.
