What Is a Medium Voltage Dry Type Transformer?
A medium voltage dry type transformer operates between 6 kV and 35 kV using cast-resin or air insulation. It is the fire-safe, low-maintenance choice for MV distribution inside buildings, substations and industrial facilities.
MV dry-type units power commercial complexes, hospitals, airports, metros, data centres and industrial plants where oil-filled transformers are restricted and reliability is critical.
- 6-35 kV class – MV dry-type units for indoor distribution.
- Cast resin insulation – vacuum-cast epoxy for moisture and pollution resistance.
- Fire-safe & compact – suits urban and occupied buildings.
- 50,000m² factory – in-house winding, casting, curing and testing.
- 350+ employees – engineering, production and export teams.
- OEM / ODM & wholesale – custom branding, packaging and volume supply.
Main Types of Medium Voltage Dry Type Transformers
We manufacture two MV dry-type types:
SCB cast resin
Standard MV dry-type for indoor substations and buildings.
SCBH amorphous
Amorphous core MV dry-type for ultra-low no-load losses.

Medium Voltage Dry Type vs Oil Immersed Transformers
Oil-immersed MV units are cheaper per kVA but need fire protection, oil containment and maintenance. MV dry-type units cost more upfront but eliminate those requirements, reduce building work and suit urban sites.
The technology choice follows site and application – our engineers confirm the right option on drawings before production.
Choosing a Medium Voltage Dry Type Transformer Manufacturer
At MV, verify partial discharge performance, thermal design and type test evidence. Factory audit access and reference projects at the same voltage class complete the picture.
Subian Electric offers a 50,000m² factory, 350+ employees, ISO9001, CE and UL certification and export to 50+ countries with in-house vacuum casting.
