As a key player in the wire export industry, we focused on addressing the client’s core pain points, leveraging our certified products, sufficient inventory, and comprehensive product range to ensure the project’s smooth progress. This case study details how we provided tailored wire solutions, including Solar Cable and H05V-K, and why our services became the top choice for this critical solar project, aligning with the common needs of the African market.

1. Challenges Facing the Sirjan Solar Power Plant

The Sirjan Solar Power Plant is a pivotal renewable energy project in Iran’s Sirjan Special Economic Zone, designed to generate stable clean electricity, ease grid pressure during peak hours, and promote sustainable development in the region. The client, an experienced EPC contractor specializing in solar projects, faced several urgent challenges when sourcing wires for the project—challenges that are common in African and Middle Eastern solar projects, making our solutions highly relevant for similar clients.

First, the project required wires that meet strict international standards, as the client needed to ensure long-term safety and compliance with local and global solar industry regulations. Many local suppliers could not provide valid TUV and UL certifications, which are mandatory for solar project components to ensure durability and safety in harsh outdoor conditions. Second, the project had a tight timeline, and the client struggled to find suppliers with sufficient inventory to avoid delays—delays that would increase project costs and miss the planned commissioning window. Third, the project needed a variety of wire types to cover different applications, from solar panel connections to control cabinet wiring, and most suppliers could only provide limited product categories, forcing the client to work with multiple vendors and increasing coordination complexity.

Additionally, the Sirjan region experiences extreme weather conditions, including high temperatures, intense UV radiation, and occasional sandstorms—similar to many African regions. This meant the wires needed to withstand harsh environmental factors, such as high heat resistance, UV protection, and wear resistance, to ensure long-term performance without frequent maintenance. The client’s core demand was clear: a one-stop supplier with certified, high-quality wires, sufficient inventory for quick delivery, and a comprehensive product range to meet all project needs.

2. Matching Project Needs with High-Quality Wires

After in-depth communication with the client, we analyzed the project’s specific requirements and designed a customized wire solution that addressed all their pain points. The core products we supplied included Solar Cable (with various specifications) and H05V-K, along with additional wires commonly used in African solar projects to ensure full compatibility and functionality.

The most critical product for the project was the 1x6mm Solar Cable—a key specification for connecting solar panels to inverters. This cable was chosen over other options for several reasons: it features a stranded tinned copper conductor (84/0.3mm) that ensures excellent conductivity and corrosion resistance, even in high-humidity environments. Its insulation and sheath are made of XLPE (cross-linked polyethylene), which offers superior heat resistance (operating temperature range: -40℃ to +90℃) and UV protection, making it ideal for the Sirjan region’s harsh outdoor conditions. Unlike standard PVC cables, which tend to become brittle and crack under prolonged UV exposure, our Solar Cable maintains structural integrity for over 25 years, matching the lifespan of the solar panels themselves. We supplied 120,000 meters of 1x6mm Solar Cable, along with 78,000 meters of 1x4mm Solar Cable and 42,000 meters of 1x2.5mm Solar Cable, to cover different connection needs across the project site.

In addition to Solar Cable, we supplied H05V-K wires, a low-voltage flexible cable widely used in African solar projects for indoor control cabinet wiring and equipment connections. The H05V-K wires we provided come in multiple sizes—including 1x0.75mm², 1x1mm², and 1x2.5mm²—with a total supply volume of 60,000 meters. This cable features a flexible stranded copper conductor and PVC insulation, making it easy to install in tight spaces, such as control panels and junction boxes. Compared to other low-voltage cables, H05V-K offers better flexibility and wear resistance, reducing installation time and minimizing the risk of wire damage during construction. 

To meet the project’s diverse needs, we also supplemented with YJV 3x16mm²+1x10mm² power cables (30,000 meters) for main power transmission. Our ability to provide all these products in one order eliminated the client’s need to coordinate with multiple suppliers, simplifying the procurement process and reducing potential delays.

3. Certified Products for Long-Term Reliability

For solar power projects, safety and reliability are non-negotiable—and our certifications were the key reason the client chose us over competitors. All our Solar Cables, H05V-K wires, and supplementary cables have obtained TUV and UL certifications, meeting strict international standards such as IEC 62930, EN 50618, and UL 4703. These certifications ensure that our products can withstand extreme temperatures, UV radiation, and mechanical stress, reducing the risk of cable failure, short circuits, and safety hazards.

Our 1x6mm Solar Cable is specifically certified to TUV standards, which includes rigorous testing for UV resistance, and flame retardancy. It also has a rated voltage of 0.6/1.0kV AC and 1.8kV DC, ensuring stable performance in the high-voltage environment of solar power systems. The H05V-K wires are certified to IEC 60227, guaranteeing compliance with low-voltage safety standards and compatibility with global electrical equipment.

Beyond certifications, we implement strict quality control throughout the production process. From raw material selection (high-purity copper conductors and high-grade insulation materials) to finished product testing, every batch of wires undergoes rigorous inspections, including conductor resistance, insulation thickness, and tensile strength tests. This ensures that each meter of wire meets our high-quality standards and the client’s project requirements, providing long-term reliability and reducing maintenance costs for the Sirjan Solar Power Plant.

4. Fast Response to Meet Tight Timelines

Thanks to our sufficient inventory, we were able to respond quickly to the client’s order. All the required wires—including the 1x6mm Solar Cable, H05V-K, and supplementary cables—were in stock when the order was placed, eliminating the need for long production lead times.

We prioritized the client’s order and arranged for professional packaging to ensure the wires were protected during transportation. The wires were packed in moisture-proof and wear-resistant wooden drums, preventing damage from humidity, dust, and mechanical impact during shipping. We coordinated with reliable international logistics partners to ensure fast and safe delivery, and the entire order arrived at the Sirjan project site much faster than the client’s expected timeline. Our efficient delivery process not only avoided project delays but also allowed the client to start installation earlier, accelerating the project’s commissioning schedule.

Throughout the delivery process, we provided real-time updates to the client, keeping them informed about the shipment status and expected arrival time.
