Wiring Design for Lighting electrical ready boards in African Rural Areas: Lower Wiring is More Suitable

Considering the current electricity situation, natural environment, and actual usage needs in rural Africa, the wire routing in the lighting electrical ready board should be designed as a bottom line first. This design can accurately adapt to the actual scene of local high temperature exposure, frequent rainstorm and dust, limited operation and maintenance conditions, and simple wiring, taking into account safety, ease of operation, and economy, and is a reasonable choice more suitable for African rural reality.

Most lighting electrical ready boards in rural Africa are installed outdoors and exposed to strong sunlight for a long time, resulting in extremely high temperatures at the top of the box. Downward wiring can prevent wires from being exposed to high temperatures at the top of the box for a long time, reduce the risk of aging and cracking of the insulation layer of the wires, and reduce short circuits and leakage accidents caused by insulation failure. It is suitable for the local hot and humid climate characteristics; At the same time, in rainstorm, rainwater flows down the surface of the box, and the downward wiring can prevent rainwater from infiltrating into the terminal along the wire, further improving the safety of electricity use.

Secondly, adapt to the local rudimentary wiring conditions and maintenance level. There is a lack of standardized underground wiring facilities in rural Africa, and overhead lines are often used for introduction. The lower wiring can be directly connected to the wiring below the outdoor overhead lines without the need for additional top entry brackets, reducing installation processes and costs, and adapting to the low-cost and simplified installation needs of rural areas. In addition, the professional ability of local operation and maintenance personnel is limited, and the offline lines are concentrated at the lower part of the box, so there is no need to climb high during maintenance, which is more convenient for troubleshooting and replacing wires, reducing the difficulty and safety risks of operation and maintenance.

In addition, downward routing can effectively avoid sandstorms. African rural areas have sandy and dusty weather, and sand and dust are prone to accumulate on the top of the box. If upward wiring is used, sand and dust can easily enter the wiring parts, leading to poor contact; The wiring terminals for the down wiring are located at the lower part of the box, which is less affected by sand and dust, can reduce equipment failures, ensure stable operation of the lighting system, and are in line with the characteristics of the local dusty environment.

To sum up, the lower wiring can specifically solve the pain points of high temperature, rainstorm, sand dust and weak operation and maintenance in African rural areas, and has more advantages in safety, practicality and economy. It is the optimal adaptation scheme for wiring in African rural lighting electrical ready boards.
