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.. 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) 5.09 /KM, weather
resistance: UV, rated
current: 57A.. The IP68 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.
