In the flagship 50 MVA substation infrastructure project in Santo Domingo, the capital of the Dominican Republic, our company was the exclusive supplier of SFZ-50 MVA/138 kV main transformers for two core substations operated by the local utility EDESUR. The commissioning of this critical equipment has become a key backbone infrastructure supporting local grid operation and reliable urban power supply.
The core distribution line equipment and raw materials we supplied to ENEE serve as the cornerstone for solidifying project quality and ensuring stable power supply, providing critical support for enhancing the country’s distribution network’s reliability and driving economic growth. Through line upgrading, equipment renewal, and structural optimization, the distribution network has achieved higher load-carrying capacity and stronger fault self-healing capabilities. The customized distribution line equipment and special raw materials we provide are tailored to the local tropical climate and grid operating conditions. Featuring low losses, high corrosion resistance, and long service life, they not only guarantee construction quality but also reduce subsequent operation and maintenance costs from the source, delivering key technical support for the safe, reliable, efficient, and sustainable operation of Honduras’ distribution network.
