Why Use Standard Photovoltaic Cables? The Importance of Compliance with EN50618

Understanding Photovoltaic Cables Photovoltaic (PV) cables, specifically the H1Z2Z2-K model, are designed to meet the rigorous demands of solar power installations. According to the EN50618 standard, these cables must be insulated with cross-linked polyolefin (XLPO) to ensure durability and safety. However, some suppliers use inferior cross-linked polyethylene (XLPE), which can compromise the cable’s performance and safety. Key Features of Standard PV Cables 1. High-Quality Insulation Material: XLPO Insulation: XLPO is chosen for its superior resistance to UV radiation, ozone, and extreme temperatures. This makes it ideal for outdoor installations where cables are exposed to harsh environmental conditions. Risks of XLPE Insulation: Inferior XLPE insulation can degrade faster, leading to potential electrical faults and fire hazards. 2. Conductor Material: Tinned Copper Conductor: The conductor used in standard PV cables is made from tinned copper, which provides excellent conductivity and resistance to corrosion. 0.25mm Single Wire Conductor: Each strand in the conductor is 0.25mm, ensuring the cable’s overall durability and performance. Why Standard PV Cables are Essential Photovoltaic cables are not like other types of cables. They are exposed to sunlight and various environmental stresses for prolonged periods. Using non-standard PV cables can lead to serious consequences, including electrical fires and system
