Low Voltage Aerial Bundle Cable (LV ABC Cable) Case Study of Distribution Network Upgrade in Nigeria
The distribution network renovation project in Nigerian towns, located in western Nigeria, features a tropical savanna climate with red soil. During the dry season, intense sunlight and high temperatures prevail, while the rainy season brings short-term rainstorms and high humidity. Additionally, the area has dense vegetation along roads. The existing low-voltage lines use bare conductors, which pose numerous operational issues: bare wires are prone to tree-line short circuits and external contact electric shock faults; conductor sway during strong winds can cause inter-phase short circuits; high leakage current losses lead to frequent power outages, poor residential electricity stability, and notable electricity theft.
The project renovation plan adopts **LV ABC low-voltage bundled overhead cables** to replace traditional bare conductors, which are installed along urban main roads. Existing concrete utility poles are modified, and additional pole positions are added to cover power supply for residential areas and commercial shops along the streets, thereby improving power supply reliability, reducing line losses, and enhancing electrical safety. The on-site construction scenario is as shown in the figure, with the construction team performing pole erection, hardware installation, ABC cable laying, and stringing operations on the urban red soil roads.
The LV ABC low-voltage bundled overhead cable is very suitable for the distribution network renovation scene in tropical red soil towns in Nigeria. This project replaces traditional bare wires with ABC cables to quickly upgrade the low-voltage power grid under limited construction conditions. In environments with high temperatures, strong ultraviolet radiation, and dense trees, it balances construction efficiency, power supply safety, and long-term operational stability. It is the preferred solution for urban and rural electrification projects in many West African countries.
