Distribution Transformers by Voltage Class
Distribution transformers from 6 kV to 132 kV class – 6-10 kV, 20 kV, 35 kV, 66 kV and 110-132 kV units – tested per IEC 60076 for each class.
What Voltage Classes Do Distribution Transformers Cover?
Distribution transformers are defined by their voltage class – from 6 kV and 10 kV distribution up to 66 kV and 110-132 kV sub-transmission. Each class has its own insulation, test and standard requirements.
Choosing the right voltage class is the first step of any transformer specification – it determines insulation, testing and cost. We manufacture every class in the distribution range.
- All distribution classes – 6 kV, 10 kV, 20 kV, 35 kV, 66 kV, 110-132 kV.
- Class-matched testing – type tests per voltage class.
- Selection support – engineering help choosing the right class.
- 50,000m²工場 – in-house winding, vacuum drying and testing.
- 350人以上の従業員 – エンジニアリング、品質、輸出チーム。.
- OEM / ODM & 卸売 – カスタムブランディング、パッケージング、ボリューム供給。.
Main Voltage Classes of Distribution Transformers
We manufacture transformers in six main voltage classes:
6-10 kV class
Standard distribution for urban and rural networks.
20-35 kV class
Medium voltage distribution for regional supply.
66-132 kV class
High voltage for sub-transmission and large supply.

Choosing the Right Voltage Class
The voltage class follows your network level – 6-10 kV for local distribution, 20-35 kV for regional supply, 66-132 kV for sub-transmission. Each class has different insulation and test requirements.
Our engineers help you confirm the right class and standard before quoting.
Choosing a Distribution Transformer Manufacturer by Voltage
Verify type test evidence for the specific voltage class you need – insulation and test requirements differ significantly between classes.
Subian Electric offers a 50,000m² factory, 350+ employees, ISO9001, CE and UL certification and export to 50+ countries across all distribution classes.
Send your voltage class and capacity – we confirm the design and price before production.
認証 & 品質保証
Our transformers are produced under ISO9001, ISO14001 and ISO45001 management systems, with CE and UL certification and type test reports per voltage class.
