1.2 Special Purpose

All Aluminum ABC Cables in the specified configurations serve various special purposes in West Africa's electrical infrastructure, addressing the region's diverse power distribution needs.

The 3*35+54.6+16mm² cable is ideal for medium-capacity distribution lines. It is commonly used to connect distribution transformers to small communities, rural villages, and small industrial facilities. In rural areas of countries like Mali and Burkina Faso, where power demand is moderate, this cable efficiently transmits electricity from the main grid to local households and small businesses. Its ability to handle medium current loads makes it suitable for powering essential appliances, agricultural pumps, and small-scale manufacturing equipment.

The 370+154mm² cable is designed for higher current loads, making it perfect for feeding power to denser urban areas, larger industrial zones, and commercial districts. In cities such as Lagos (Nigeria) and Accra (Ghana), where there is a high concentration of residential, commercial, and industrial activities, this cable ensures a stable power supply. It can handle the electricity demands of large factories, shopping malls, high-rise buildings, and multiple residential complexes, supporting the economic activities in these areas.

The 6+1*16mm² cable is tailored for low-voltage networks. It is widely used in residential street lighting systems, providing electricity to street lamps in neighborhoods across West Africa. Additionally, it is suitable for small-scale agricultural applications, such as powering irrigation systems in small farms in countries like Senegal and Togo. This cable's multiple conductors allow for flexible distribution of power to various low-power devices, ensuring efficient and safe operation.

Another special purpose of these ABC cables is in rural electrification projects. West Africa has many remote areas with limited access to electricity, and these cables, with their lightweight and easy installation features, are crucial for extending the power grid to these regions. They can be deployed in areas with difficult terrain, such as hilly regions or dense forests, where traditional heavy cables would be challenging to install.

1.3 Materials and Styles

The materials and styles of All Aluminum ABC Cables are carefully chosen to meet the demands of West Africa's electrical overhead applications.

The conductors are made of high-purity aluminum (99.5% purity or higher). Aluminum is selected for its favorable combination of conductivity, strength, and weight. While it has slightly lower conductivity than copper, its lighter weight reduces the load on overhead structures, which is essential in areas where infrastructure may be less robust. The Aluminum Conductors are stranded, consisting of multiple small Aluminum Wires twisted together. This stranded design enhances the Flexibility of the cables, making them easier to handle during installation and more resistant to fatigue from wind-induced vibrations, which are common in the region.

The sheath material of these ABC cables is typically polyethylene (PE) or cross-linked polyethylene (XLPE). PE is a cost-effective option with good flexibility and Chemical Resistance, suitable for general overhead applications. XLPE, on the other hand, offers superior thermal stability and resistance to aging, making it more durable in harsh environmental conditions. Both materials provide excellent protection against moisture, UV radiation, and chemical corrosion, which are prevalent in West Africa's climate—high humidity, intense sunlight, and occasional exposure to salt spray in coastal areas.

In terms of style, these are multicore overhead cables. The 335+54.6+16mm² and 370+154mm² cables have a compact design where the phase conductors, neutral/messenger wire, and auxiliary conductor are integrated within a single sheath. This integration simplifies installation and reduces the risk of conductor separation, enhancing the overall reliability of the Overhead Line. The 6+116mm² cable also features multiple conductors within one sheath, allowing for easy distribution of power to multiple low-voltage devices.

Some variants of these ABC cables may include a messenger wire, which is a stronger conductor (like the 54.6mm² and 54mm² conductors in the specified configurations) that provides mechanical support to the cable. This messenger wire helps to reduce the tension on the phase conductors, increasing the cable's stability and lifespan, especially in areas with strong winds.

1.4 Production Process

The production process of All Aluminum ABC Cables involves several precise steps to ensure quality and performance, especially tailored for West Africa's conditions.

The first step is the production of Aluminum Conductors. High-purity aluminum ingots are melted and cast into rods. These rods are then drawn through a series of dies to reduce their diameter and form thin Aluminum Wires. The wires are stranded together using a stranding machine, with the number of wires depending on the desired conductor size. For example, a 35mm² conductor is made by stranding multiple 2mm diameter aluminum wires. The stranding process ensures the conductor has the necessary flexibility and current-carrying capacity.

After stranding, the conductors undergo surface treatment to remove any oxides or contaminants. This treatment ensures good adhesion between the conductor and the Insulation Material.

Next, the insulation is applied to each phase conductor. If PE is used as the insulation material, it is extruded onto the conductor using an extrusion machine. The extrusion process involves melting the PE and forcing it through a die to form a uniform insulation layer around the conductor. For XLPE insulation, the process is similar, but after extrusion, the insulation undergoes a cross-linking process. This can be done through chemical cross-linking (using peroxides) or radiation cross-linking (using electron beams), which enhances the material's thermal and mechanical properties.

Once the insulated phase conductors are ready, they are combined with the neutral/messenger wire and auxiliary conductor (if applicable) in a cabling machine. The conductors are arranged in a specific configuration within the sheath, ensuring proper spacing and alignment.

The final step is the extrusion of the outer sheath. The combined conductors are passed through an extrusion machine, where PE or XLPE is extruded around them to form the outer sheath. The sheath is cooled and solidified in a water bath. After production, the cables undergo rigorous testing, including electrical tests (insulation resistance, voltage withstand) and mechanical tests (tensile strength, elongation) to ensure they meet the required standards.

2. General Product Information

2.1 Packaging

The packaging of All Aluminum ABC Cables is designed to protect them during transportation and storage, ensuring they reach their destination in West Africa in good condition.

The cables are typically spooled onto large wooden or steel reels. The size of the reels depends on the length of the cable. For example, a 500-meter length of the 3*35+54.6+16mm² cable is spooled onto a reel with a diameter of approximately 1.2 meters. The reels are fitted with flanges to prevent the cable from slipping off during handling.

Each reel is labeled with detailed information, including the cable type (All Aluminum ABC), configuration (e.g., 3*35+54.6+16mm²), length, voltage rating, batch number, production date, and compliance with relevant standards (such as IEC and WAPP). This information helps utilities and contractors identify the correct cable for their specific applications.

The cable ends are sealed with moisture-proof caps to prevent water and dust from entering the cable core, which could damage the insulation. The reels are wrapped with a layer of heavy-duty plastic film to provide additional protection against moisture and physical damage. For long-distance transportation, especially to remote areas in West Africa, the reels may be placed in wooden crates to further enhance protection.

2.2 Transportation

Transporting All Aluminum ABC Cables to West Africa requires careful planning to handle the challenges of long distances and varying terrain.

For international transportation, the cables are usually shipped by sea in containers. The reels are loaded into 20-foot or 40-foot containers, depending on their size and quantity. The reels are secured within the container using steel straps and wooden blocks to prevent movement during transit, which could cause damage to the cables or the container.

Once the containers arrive at West African ports (such as Lagos in Nigeria or Abidjan in Côte d’Ivoire), the reels are unloaded and transported to their final destinations by road. In urban areas, trucks with flatbed trailers are used to carry the reels. In rural or remote areas, where roads may be unpaved or narrow, smaller trucks or even vehicles with special off-road capabilities may be employed.

During transportation, it is important to protect the cables from extreme temperatures and direct sunlight. High temperatures can cause the sheath material to soften, while prolonged exposure to sunlight can accelerate aging. Therefore, the reels are often covered with tarpaulins during road transportation.
