Discover Core Advantages of Transformers to Optimize Your Power Layout
Remarkable Advantages of Unicore Pole Mount Transformer
Energy-Efficient Low-Loss Design
Unicore pole-mounted transformers are engineered with high-quality CRGO silicon steel cores to minimise no-load losses, reducing energy waste during continuous operation. Lower core losses translate directly into reduced operating costs and improved efficiency across your entire distribution network over the transformer’s service life.
Maintenance-Free Oil-Immersed Cooling
Each unit utilises oil-immersed self-cooling (ONAN) technology, eliminating the need for external cooling equipment or regular maintenance intervention. The hermetically sealed tank design prevents moisture ingress and oil leakage, ensuring consistent performance and extended service life in outdoor overhead installations.
Built for Harsh Environments
Unicore pole-mounted transformers are designed and tested for reliable operation in demanding climatic conditions — including high-humidity tropical environments, extreme temperature ranges, coastal salt-air exposure, and high UV radiation zones — making them suitable for deployment across Africa, Southeast Asia, the Middle East, and beyond.
Protective Accessory Compatibility
Unicore pole-mounted transformers are designed for compatibility with standard overhead line protection accessories — including dropout fuses, surge arresters, and disconnectors — allowing straightforward integration into existing overhead distribution networks without modification to your standard protection scheme.
Voltage Regulation via Tap Changer
An off-circuit tap changer is available on all Unicore pole-mounted transformer units, allowing voltage ratio adjustment to compensate for line voltage variation and maintain stable secondary voltage output — particularly important for rural distribution lines where voltage drop across long distances is a common challenge.
Corrosion-Resistant Tank and Fittings
Every Unicore pole-mounted transformer tank and external fitting is treated with multi-stage surface preparation — including shot blasting, phosphating, and high-build epoxy primer — followed by weather-resistant topcoat finishing, ensuring long-term protection against rust, UV degradation, and atmospheric corrosion in outdoor overhead installations.

What Our Clients Say
Perfect Fit for Our Overhead Network
“Unicore configured the primary voltage precisely to our local 33kV grid standard, saving our engineering team significant on-site adaptation work. The units were compact, lightweight, and straightforward to install. Lead time was competitive and the export documentation was complete and accurate on first submission.”
Ahmed Al-Rashidi

⭐⭐⭐⭐⭐
Tap Changer Solved Our Voltage Drop Issue
“Our rural distribution lines span considerable distances, and voltage drop at the end of the line was an ongoing problem. Unicore recommended units with off-circuit tap changers, which allowed our field teams to fine-tune the secondary voltage on site. It was exactly the right technical solution for our network.”
