1. Urgent Renovation Needs of Garissa Solar Power Plant

The Garissa Solar Power Plant, with a total installed capacity of 50MW, is a key renewable energy project in Kenya, playing a vital role in alleviating local power shortages and promoting regional economic development. After years of operation in the harsh outdoor environment of Garissa—characterized by strong ultraviolet radiation, extreme temperature differences (ranging from -5℃ to 45℃), and occasional sandstorms—the original cables of the power plant began to show serious aging, insulation damage, and poor corrosion resistance. These issues not only affected the stable transmission of electrical energy but also posed potential safety hazards, including short circuits and even fires, which could lead to significant economic losses and power outages.

The client, responsible for the renovation and operation of the Garissa Solar Power Plant, had three core pain points in the cable selection process. First, the harsh local environment required cables with excellent weather resistance, UV resistance, and corrosion resistance, which ordinary cables on the market could not meet. Second, the project involved both PV module connection and power distribution system renovation, requiring a complete range of cable types and specifications to avoid multiple purchases from different suppliers, which would delay the project progress. Third, the client prioritized product quality and safety, as the stability of the cables directly determined the operational efficiency and service life of the power plant; they needed cables that met international standards and held authoritative certifications to ensure long-term reliable operation.

Before cooperating with us, the client had contacted several cable suppliers but failed to find a suitable partner. Some suppliers lacked experience in large-scale solar power projects and could not provide targeted solutions; others had incomplete product categories or failed to meet the required quality standards. When the client learned about our rich experience in international solar energy projects and comprehensive product supply capacity, they took the initiative to contact us for a detailed consultation, hoping we could provide a one-stop cable solution.

After in-depth communication with the client, we fully understood their project needs, pain points, and quality requirements. Combining our experience in similar African solar projects and the technical characteristics of the Garissa Power Plant, we customized a comprehensive cable solution centered on H1Z2Z2-K Solar Cable and H07V-K cables, ensuring that every detail met the project’s actual needs.

First, for the PV module connection part, we recommended the H1Z2Z2-K Solar Cable, which is specifically designed for solar power systems and perfectly adapted to Garissa’s harsh outdoor environment. Unlike ordinary solar cables, the H1Z2Z2-K Solar Cable adopts high-quality tinned copper conductors, which have better electrical conductivity and corrosion resistance, effectively preventing oxidation and damage caused by sand and dust. Its insulation and sheath are made of halogen-free flame-retardant materials that can withstand long-term UV radiation and extreme temperature changes, with a working temperature range of -40℃ to +90℃ and a conductor maximum operating temperature of +120℃, far exceeding the client’s requirements. The cable also meets the EN 50618:2014 standard, ensuring stable performance in high-voltage DC environments (1.5kV DC) commonly used in PV systems.

In this project, the client purchased a total of 80,000 meters of H1Z2Z2-K Solar Cable with various specifications to meet different connection needs: the key specification 1×4 mm² H1Z2Z2-K Solar Cable was used for the connection between PV modules and combiner boxes, with a total purchase volume of 35,000 meters; other specifications included 1×2.5 mm² (25,000 meters) for short-distance module connections and 1×6 mm² (20,000 meters) for connections between combiner boxes and inverters. The 1×4 mm² H1Z2Z2-K Solar Cable was selected for its balanced current-carrying capacity and flexibility, which can effectively reduce power loss during transmission and facilitate installation in the complex terrain of the power plant.

Second, for the power distribution system and indoor wiring of the power plant, we provided the H07V-K cable, a flexible fixed wiring cable with excellent performance and wide applicability. The H07V-K cable uses bare copper conductors, PVC insulation, and a flame-retardant sheath, with a rated voltage of 450/750V AC, suitable for indoor and outdoor fixed wiring in power distribution cabinets, control systems, and other equipment. It has good flexibility, making it easy to install in narrow spaces, and its flame-retardant performance can effectively reduce the risk of fire, ensuring the safety of the power plant’s internal electrical system. The client purchased 50,000 meters of H07V-K cables with specifications including 1×10 mm² (15,000 meters), 1×16 mm² (12,000 meters), 1×25 mm² (10,000 meters), and 2×4 mm² (13,000 meters), covering all indoor and outdoor power distribution needs of the renovation project.
