The solar cable 10mm twin, featuring two insulated conductors each with a cross - sectional area of 10 square millimeters, is a high - capacity solution designed for demanding photovoltaic (PV) applications. Engineered to handle substantial power loads, it plays a critical role in large - scale solar setups where efficient and reliable power transmission is paramount.
I. Robust Structure and Material Configuration
1.1 Conductors
Crafted from high - purity oxygen - free copper, the conductors of the 10mm twin solar cable offer superior electrical conductivity. With a purity often exceeding 99.97%, these conductors significantly minimize electrical resistance, reducing power losses during the transmission of direct current (DC) power generated by solar panels. The tin - plating applied to the copper conductors provides enhanced protection against oxidation, ensuring long - term stability in outdoor environments. The stranded construction of the conductors not only provides flexibility for installation around complex structures but also enables the cable to withstand mechanical stress, making it suitable for large - scale projects where the cable may need to be routed over long distances or through challenging terrains.
1.2 Insulation
Inner Insulation: Cross - linked polyethylene (XLPE) or cross - linked polyolefin (XLPO) serves as the inner insulation material, offering excellent electrical isolation. This insulation effectively prevents DC current leakage, safeguarding the integrity of the PV system. Capable of operating within a wide temperature range from - 40°C to + 90°C and withstanding short - term temperature spikes up to + 120°C, it ensures consistent performance in various climates, from the frigid conditions of high - altitude regions to the intense heat of desert - based solar farms.
Insulation Thickness: The insulation thickness of the 10mm twin solar cable is carefully optimized. While a thicker insulation layer provides enhanced protection, it also impacts the cable's diameter and flexibility. Manufacturers strike a balance to ensure that the cable offers robust electrical insulation while remaining manageable during installation, even in tight spaces or complex installation scenarios.
1.3 Outer Sheath
Constructed from UV - stabilized, halogen - free thermoplastic elastomer (TPE), the outer sheath provides comprehensive protection against environmental elements. In large - scale solar installations, the cable is exposed to prolonged sunlight, heavy rain, strong winds, and other harsh conditions. The UV - stabilization property of the TPE sheath prevents degradation due to sunlight exposure, while its moisture - and abrasion - resistant characteristics safeguard the internal components. Standard color - coding, with black for the negative conductor and red or brown for the positive, simplifies the installation process and reduces the risk of incorrect connections, which is crucial for the proper functioning of high - power PV systems.
