What Is an Electrical Power Line Transformer?
A power line transformer connects to overhead distribution lines and steps voltage down for local supply. It is built for outdoor, all-weather duty with line and pole mounting in mind.
Utilities specify line transformers for rural, suburban and urban overhead networks – compact units that are easy to install, maintain and replace.
- Overhead line duty – built for outdoor, all-weather operation.
- Pole mounted – single and three-phase pole units.
- 5 kVA – 2500 kVA – capacity range for line distribution.
- 50,000m² factory – in-house winding, vacuum drying and testing.
- 350+ employees – engineering, quality and export teams.
- OEM / ODM & wholesale – custom branding, packaging and volume supply.
Main Types of Power Line Transformers
We manufacture three line transformer types:
Single-phase pole mounted
Compact units for rural and single-phase networks.
Three-phase pole mounted
Units for small three-phase distribution.
Pad mounted
Ground-level units for urban and commercial lines.

Pole Mounted vs Pad Mounted Line Transformers
Pole-mounted units serve overhead networks economically; pad-mounted units sit at ground level in enclosures for urban sites without overhead space.
We manufacture both – the choice follows your network and site configuration.
