Powering Nouadhibou’s PV Landscape Lighting Project in Mauritania

In early 2021, we partnered with a local engineering firm in Nouadhibou, Mauritania, to supply high-quality wires for the city’s key PV landscape lighting project. This project aimed to upgrade the city’s public lighting system, integrating solar energy to enhance nighttime safety, beautify urban landscapes, and reduce reliance on traditional grid power—aligning with Mauritania’s national goal of energy transition and universal electrification by 2030. As a professional wire and cable exporter with rich experience in African projects, we successfully addressed the client’s core pain points and delivered a comprehensive wiring solution that met the project’s strict requirements for quality, cost, and delivery speed.

1. Challenges Facing Nouadhibou’s PV Landscape Lighting Upgrade

Nouadhibou, a coastal city in northwestern Mauritania, is an important economic and transportation hub. The local government launched the PV landscape lighting project to improve the city’s nighttime image and public safety, covering major roads, squares, and coastal scenic areas. However, the client, a local engineering company responsible for project implementation, encountered several critical challenges in the wiring phase, which almost delayed the project progress.

First, the project required wires that could adapt to Nouadhibou’s harsh natural environment—high temperatures, strong coastal winds, and occasional sandstorms. Common wires on the market were either too fragile to withstand long-term exposure to extreme weather or too expensive to fit the project’s limited budget. Second, the client lacked experience in PV lighting projects, especially in selecting wires that match solar power systems. They struggled to find a supplier that could provide both technical support and cost-effective products. Third, the project had a tight schedule, and the client needed a supplier with efficient delivery capabilities to avoid delaying the overall construction timeline. Finally, as a project involving public facilities, all wires had to meet international safety standards and pass local certification inspections to ensure long-term safe operation.

After comparing multiple suppliers, the client chose us—Dongguan Greater Wire & Cable Co., Ltd.—due to our strong project experience in Africa, competitive pricing, and reliable product quality. Our team immediately started communicating with the client to understand the project’s specific needs and design a tailored wiring solution.

2. Selecting the Right Wires for the PV Landscape Lighting Project

Based on the project’s characteristics—PV power supply, outdoor installation, and harsh environmental conditions—we recommended a combination of wires that perfectly matched the client’s needs, including the core models PV1-F, H07V-K, and H07Z1-K. We also supplemented other commonly used wires in the African market to ensure the completeness of the wiring system.

The PV1-F solar cable is specially designed for PV systems, which is higher than the standard 0.6/1kV AC wires, making it more suitable for the high-voltage output of solar panels. We supplied PV1-F in sizes 1x2.5mm², 1x4mm², and 1x6mm². Compared with ordinary power cables, PV1-F has excellent UV resistance and weather resistance, which can effectively resist the damage caused by long-term exposure to sunlight and sandstorms in Nouadhibou. Its flame-retardant insulation layer also reduces the risk of fire, which is crucial for outdoor public facilities.

For the indoor and outdoor low-voltage wiring of the lighting system, we recommended H07V-K single-core wires, a popular choice in the African market due to their flexibility and cost-effectiveness. We provided H07V-K in sizes 1.5mm², 2.5mm², and 4mm². H07V-K uses PVC insulation and multi-strand fine-twisted copper conductors, which are more flexible than single-strand wires, making them easy to install in narrow spaces and around corners—solving the client’s problem of difficult installation in complex terrain. Compared with similar products from other suppliers, our H07V-K has a thicker insulation layer, improving its durability and resistance to wear and tear, which is essential for long-term outdoor use.

A key part of the solution is the H07Z1-K, specifically the 1x6mm H07Z1-K model. H07Z1-K is a halogen-free, flame-retardant wire with a rated voltage of 450/750V, complying with IEC 60228 and EN 50525 standards. It is specially designed for public places with high safety requirements, such as the squares and scenic areas in this project. The halogen-free insulation layer of H07Z1-K produces no toxic or corrosive gases in case of fire, protecting the safety of people and equipment. Compared with H07V-K, H07Z1-K has higher flame-retardant performance and is more suitable for areas with dense crowds. The 1x6mm size was selected to meet the high-current transmission needs of the main line of the lighting system, ensuring stable power supply to each lighting fixture.

3. Certifications and Quality Control to Meet African Standards

We understand that safety is the top priority for public projects in Africa, and certification is a key threshold for wire export to the African market. Unlike many suppliers that only provide basic certificates, we hold a full set of international certifications, including UL, TUV, CE, and CB, as well as the COC (Certificate of Conformity) required for export to Mauritania—which is a mandatory document for customs clearance in African countries. This eliminated the client’s concern about customs detention due to incomplete certification, a common pain point for African importers.

Before delivery, our professional quality control team conducted strict inspections on all wires. We tested the electrical performance (conductivity, insulation resistance), mechanical performance (flexibility, tensile strength), and environmental adaptability (high-temperature resistance, UV resistance) of each batch of wires, ensuring that all products meet the project’s requirements and international standards. For the H07Z1-K model, we conducted additional flame-retardant and halogen-free tests to confirm their safety performance. All test reports were provided to the client, giving them full confidence in the product quality.

We also provided technical guidance to the client, explaining the installation precautions of each type of wire—such as the bending radius of PV1-F solar cables and the waterproof treatment of H07Z1-K in outdoor environments. This professional support helped the client avoid installation errors that could affect the project’s safety and service life.

4. Fast and Efficient to Meet Project Deadlines

The client emphasized that the project had a tight schedule and that any delay in wire delivery would affect the overall construction progress. We took this as a top priority and optimized our production and logistics processes to ensure fast delivery. After confirming the order, we arranged production immediately, giving priority to the production of the core models PV1-F, H07V-K, and H07Z1-K. Our advanced production equipment and professional team allowed us to complete the production in a short time.

In terms of logistics, we cooperated with experienced international logistics companies that are familiar with the African market, choosing the most efficient shipping route to Nouadhibou Port. We also handled all customs clearance documents in advance, including the COC certificate, commercial invoice, and packing list, to avoid delays in customs inspection. The entire delivery process was fast and smooth, and the wires arrived at the project site well ahead of the client’s expected time, ensuring that the construction progress was not affected. The client highly recognized our efficient delivery capability, noting that our speed was far beyond their expectations compared with other suppliers they had contacted before.
