LV XLPE Insulated Aerial Bundled Cables 2, 3 & 4 Core Copper
■ Voltage drops are single phase for 2 &3 core cables and three-phase for 4 core cables. Continuous current ratings are based on an ambient temperature at 40℃
■ maximum conductor temperature of 80℃ and solar radiation intensity of 1000W/mm2. Rating for 2&3core cables are based on all cores fully loaded. Ratings for 4 core cables are based on a lightly loaded neutral. Fault current ratings are based on initial and final conductor temperatures of 80℃ 210℃ respectively.
