New Caledonia South Province Nickel Mine Renovation Project

Nickel mining is the backbone of New Caledonia’s economy, accounting for 6% of the country’s GDP and 24% of private employment, with nickel ore and its derivatives representing 90% of the nation’s total export value. In 2024, as local nickel mines gradually resumed production with support from French government emergency financial measures, a key mining enterprise in the South Province launched a large-scale renovation project to upgrade its aging infrastructure and expand production capacity, aiming to keep up with the growing global demand for nickel products. Dongguan GERITEL Electrical Co., Ltd. (GERITEL) was honored to partner with this enterprise, providing high-quality mining cable, SWA Cable, and Elastomer Cable to solve the project’s critical wiring challenges. This case details how we leveraged our product advantages, SAA certification, and professional service to deliver a reliable solution for the nickel mine renovation, creating win-win value for both parties.

1. Challenges of Nickel Mine Renovation in New Caledonia’s South Province

The project is located in the South Province of New Caledonia, a region rich in nickel reserves—home to approximately 10% of the world’s total nickel deposits. The client, a local leading nickel mining enterprise, was undertaking a comprehensive renovation of its existing nickel mining and processing facilities after an 8-month production suspension. The goal was to improve mining efficiency, enhance operational safety, and meet the increasing production targets, as the company aimed to replicate the record-breaking nickel production achieved in 2025, when it produced 36,030 tons of nickel and mined 1.176 million tons of ore.

However, the renovation faced significant wiring challenges, which became the biggest bottleneck for the project’s progress. The client’s existing cables were outdated, with frequent failures such as insulation damage, cable breakage, and poor corrosion resistance—problems exacerbated by the harsh mining environment. The nickel mine’s strip mining operations involve removing large amounts of overburden, exposing cables to rocky terrain, high humidity, and occasional chemical corrosion from mining by-products. Additionally, underground blasting operations often caused cable breakages, leading to unplanned production downtime and safety risks.

The client’s core needs were clear: they required cables that could withstand the harsh mining environment, meet local safety standards, cover all application scenarios (from underground mining equipment to surface processing facilities), and be delivered quickly to avoid delaying the renovation schedule. They had previously tested cables from other suppliers, but these failed to meet the durability and safety requirements, and the limited product range meant they had to source from multiple suppliers, increasing procurement costs and coordination complexity. After rigorous screening, the client chose GERITEL for our comprehensive product portfolio, SAA certification (a key requirement for entering Oceania’s electrical market), and proven experience in mining cable solutions.

2. Tailored Cables for Nickel Mine Renovation

After in-depth communication with the client and on-site investigation (conducted remotely due to geographical constraints), our team identified three core application scenarios and matched them with the most suitable cables, addressing the client’s pain points one by one. We focused on explaining why each cable was chosen over alternatives, highlighting their unique advantages for nickel mining environments.

2.1 Mining Cables: The Core of Underground and Mining Equipment Wiring

The mining cable is the lifeline of the nickel mine’s operations, as it needs to connect underground mining equipment (such as excavators, loaders, and crushers) to the power supply system, ensuring stable power transmission in harsh underground conditions. The client’s previous cables often suffered from insulation aging and breakage due to frequent bending and exposure to moisture and dust, leading to frequent power outages.

We provided Mining Cables (model UY and MY) with customized specifications to meet the project’s needs. The key specifications included 3×25+1×16 mm², 3×35+1×16 mm², and 3×50+1×16 mm², all designed with high-quality copper conductors and XJ-00A rubber insulation, which offers excellent flexibility and wear resistance. Compared to ordinary industrial cables, our mining cable features a thickened chlorinated polyethylene (CPE) sheath that is resistant to oil, acid, and alkali—critical for withstanding the chemical corrosion from nickel ore processing. Additionally, the cables are flame-retardant (meeting MT386-1995 standards) and have an insulation resistance of no less than 100 MΩ·km at 20℃, ensuring safe operation even in high-humidity underground environments. This made our mining cable far more durable than the client’s previous options, which lacked corrosion resistance and flame-retardant properties.

2.2 SWA Cable: Reliable Power Transmission for Surface and Direct Burial

For surface power distribution and direct burial wiring (connecting the mine’s substation to surface processing facilities and underground power points), the client needed cables with strong mechanical protection and tensile strength. The rocky terrain of the South Province’s nickel mines meant that cables buried underground were prone to crushing and rodent damage, while surface cables had to withstand UV exposure and extreme temperature changes.

We recommended SWA Cable (Steel Wire Armored Cable) with specifications including 4×16 mm², 4×25 mm², and 4×35 mm². Unlike STA (Steel Tape Armored) cables, which only provide moderate crush resistance, SWA Cable uses steel wires as the reinforcing component, offering superior tensile strength and resistance to bending stresses—making it ideal for direct burial in rocky soil and harsh environments. The cable’s XLPE insulation ensures excellent electrical performance and heat resistance, with a long service life even in extreme temperatures (ranging from -40℃ to 90℃). The steel wire armor also provides effective protection against mechanical damage, reducing the risk of cable breakage during installation and operation. This made SWA Cable the perfect choice for the mine’s surface and direct burial wiring, outperforming ordinary unarmored cables that were easily damaged in the rocky terrain.

2.3 Elastomer Cable: Flexible Connection for Mobile Mining Equipment

Mobile mining equipment (such as mobile crushers and conveyor belts) requires cables that are highly flexible, able to withstand frequent bending and movement without breaking. The client’s previous cables for mobile equipment were rigid, leading to frequent breakages and unplanned downtime—costing the enterprise valuable production time.

Our Elastomer Cable (model H07RN-F) was the ideal solution, with specifications including 3×4+1×4 mm², 3×6+1×6 mm², and 3×10+1×6 mm². Made from high-quality elastomer insulation and sheath materials, this cable offers exceptional flexibility and fatigue resistance, able to withstand thousands of bending cycles without damage. It also has excellent oil and chemical resistance, making it suitable for use in the oily and dusty environment of nickel mining equipment. Compared to traditional rubber cables, Elastomer Cable has better low-temperature flexibility, ensuring stable performance even in New Caledonia’s cool winter months. This flexibility eliminated the client’s problem of frequent cable breakages in mobile equipment, significantly reducing downtime.
