The twin 13.5mm solar cable, with each core having a cross - sectional area of 13.5 square millimeters, is a high - capacity cable designed for heavy - duty power transmission in solar energy systems. Tailored to handle substantial electrical loads, it stands as a key component in large - scale solar setups, offering enhanced performance and reliability compared to smaller - gauge counterparts.

Constructed from high - purity oxygen - free copper with a purity of at least 99.97%, the conductors of the twin 13.5mm solar cable are engineered for superior conductivity. Tin - plating is commonly applied, providing an extra layer of protection against oxidation, which is crucial in outdoor environments. In large - scale solar farms located in coastal regions, where the cables face constant exposure to salt mist and humidity, the tin - coated copper conductors maintain stable electrical performance over extended periods. The stranded design of the conductors offers a balance between flexibility and strength, allowing installers to maneuver the cable around complex infrastructure, such as large - scale ground - mounted arrays and extensive rooftop layouts, without compromising the integrity of the wire.

Cross - linked polyethylene (XLPE) or cross - linked polyolefin (XLPO) serves as the inner insulation material. This insulation provides excellent electrical isolation, effectively preventing electrical leakage and short circuits. With the ability to withstand a wide temperature range, from extreme colds of - 40°C to sweltering heat of + 90°C, and endure short - term temperature spikes up to + 120°C, the cable can operate reliably in diverse climates. The insulation thickness of the twin 13.5mm solar cable is carefully calibrated to offer robust protection for the conductors while keeping the overall cable dimensions manageable. This ensures that the cable can be installed in various conduit sizes and tight spaces commonly found in large - scale solar installations.

Made from UV - stabilized, halogen - free thermoplastic elastomer (TPE), the outer sheath acts as a formidable barrier against environmental factors. In sun - baked desert regions, the UV - stabilization property of the TPE sheath prevents the cable from degrading due to prolonged exposure to intense sunlight. It also resists moisture, abrasion, and exposure to mild chemicals, safeguarding the cable's internal components. In industrial solar setups, where the cable may be exposed to chemical fumes and dust, the outer sheath ensures the cable's long - term functionality. Similar to other solar cables, it features standard color - coding, with black typically indicating the negative conductor and red or brown signifying the positive conductor, facilitating correct installation and minimizing connection errors.

Boasting a total current - carrying capacity of 110A at 90°C, the twin 13.5mm solar cable is well - equipped to handle the significant power output of large - scale solar systems. In a 30kW commercial solar installation on the roof of a multi - story office building, this cable can efficiently transmit the power generated by numerous solar panels to the inverter, ensuring minimal power loss during the process. Even when the cable runs over longer distances, such as 30 - 50 meters from the panels to the central inverter, its low resistance design helps maintain high - efficiency power transfer, maximizing the energy harvested from the sun and optimizing the system's overall performance.

Built with top - notch materials and a sturdy construction, the twin 13.5mm solar cable has an extended service life, typically ranging from 20 - 30 years. In remote rural solar installations, where the cable is exposed to harsh weather conditions, including strong winds, heavy snow, and extreme temperature fluctuations, its durability ensures consistent performance. The cable's resistance to mechanical stress, such as accidental impacts during installation and vibrations from nearby equipment, further enhances its long - term reliability. This longevity reduces the frequency of cable replacements, resulting in substantial cost savings for solar system owners and operators over the life cycle of the installation.

Despite its relatively large size, the twin 13.5mm solar cable offers good flexibility. Its stranded conductor design, combined with the flexible insulation and outer sheath materials, allows it to be routed through large - diameter conduits and around complex building structures with relative ease. The twin - core design simplifies the installation process compared to using two separate single - core cables, reducing installation time and the risk of incorrect connections. Compatibility with standard connectors, like MC4 - type connectors, further streamlines the installation, making it accessible for both professional installers working on large - scale projects and those overseeing complex solar installations in industrial and commercial settings.

In large commercial buildings, such as shopping malls, airports, and large industrial complexes, the twin 13.5mm solar cable is an ideal choice for power transmission. These facilities often feature extensive solar arrays with high power generation capacities. For instance, in a large shopping mall with a 50kW solar installation, the cable can effectively carry the electricity generated by the solar panels to the building's electrical infrastructure, helping the mall reduce its reliance on the grid and lower energy costs. Its high - capacity power - handling ability ensures that the power generated is efficiently utilized within the building or fed back into the grid.

Utility - scale solar farms, which consist of thousands of solar panels spread over vast areas, rely on the twin 13.5mm solar cable for efficient power collection and transmission. The cable can connect individual panels within arrays and transmit the power over long distances to central inverters and grid connection points. In a large - scale solar farm spanning several acres, the cable's ability to handle high currents and resist environmental degradation is essential for maintaining the farm's operational efficiency and ensuring a stable supply of renewable energy to the grid.

Industrial buildings with large rooftop areas, such as factories and warehouses, are increasingly adopting solar power to meet their substantial energy demands. The twin 13.5mm solar cable is well - suited for these industrial rooftop solar projects. In a manufacturing factory with a 40kW solar installation on its roof, the cable can transmit the generated power to the factory's electrical system, powering machinery, lighting, and other equipment. Its durability and high - capacity performance make it a reliable option for industrial settings, where continuous and stable power supply is crucial for production operations.

In conclusion, the twin 13.5mm solar cable is a reliable and high - performing solution for large - scale solar power applications. Its robust construction, high - capacity power - handling capabilities, and ease of installation make it an essential component in the development and operation of efficient solar energy systems, contributing significantly to the growth of the renewable energy sector.
