【𝐓𝐢𝐧𝐧𝐞𝐝 𝐑𝐞𝐝 𝐂𝐨𝐩𝐩𝐞𝐫 𝐖𝐢𝐫𝐞】: The one pair ( 1 piece black + 1 piece red ) 10AWG solar panel wire is made of tin plated conductive copper material, which has better conductivity, thermal conductivity, and corrosion resistance than pure copper, can reduce power loss during use to improves charging efficiency. | 【𝟏𝟎𝐀𝐖𝐆 𝐒𝐨𝐥𝐚𝐫 𝐂𝐚𝐛𝐥𝐞】: Professional photovoltaic solar cable, TÜV, CE certification, cross-sectional area: 6mm², temperature range: environment -40°C-90°C, test voltage: 6500V, conductor resistance: (20°C) ≤≤5.09Ω/KM, weather resistance: UV, rated current: 57A. | 【𝐃𝐮𝐫𝐚𝐛𝐥𝐞 𝐒𝐨𝐥𝐚𝐫 𝐄𝐱𝐭𝐞𝐧𝐬𝐢𝐨𝐧 𝐂𝐚𝐛𝐥𝐞】: The IP67 level of waterproofing allows the solar panel wire to work outdoors for a long time (about 30 years), and the PV solar cable shell is made of durable PPO Flame Retardant insulating material, extra-thick insulation can withstand extreme heat and cold -40℉-194℉(-40℃-90℃). Designed for Extreme Weather, It can be buried directly in the ground. | 【𝐄𝐚𝐬𝐲 𝐭𝐨 𝐎𝐩𝐞𝐧 & 𝐋𝐨𝐜𝐤】: Each solar extension wire is equipped with male and female connector at the wire ends (has been installed). which can be locked and opened by a stable self-locking system to connect multiple cables together for longer length. One end is connected to the solar panel, another is connected to the solar charge controller, which makes it easy to operate. | 【𝐖𝐢𝐝𝐞 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧】: Solar extension cable is moisture, UV and corrosion resistant. Designed for long life and outdoor applications. Suitable for solar power plants, PV connectors, boats, RVs, and can be easily connected to similar connector types supplied with most solar modules. Choose from various wire gauge sizes (10AWG and 12 AWG) and length options (10ft, 20ft, 30ft, 40ft, 50ft, 60ft, 70ft, 100ft) to fit your specific solar panel system needs.
