As African utilities extend their networks, many rural expansion lines experience voltage drop due to long transmission distance, seasonal demand variations and insufficient upstream supply. This leads to unstable power for farms, water pumps, clinics and local industries.
The 33kV/11kV Auto Transformer stabilizes voltage along extended feeders by delivering consistent 11kV output despite upstream fluctuations. Its efficient regulation design reduces drop on long distribution lines, enhances supply reliability and supports balanced load development for community services, agricultural facilities and township electrification projects.
Hentg Power is a professional power equipment manufacturer delivering distribution transformers, auto transformers and power solutions for global EPC contractors, utilities and industrial users.
Through engineering expertise, IEC-compliant production, strict quality control and strong customization capability, we supply reliable equipment for weak-grid regions, rural electrification, substations and infrastructure upgrades.
