Of which:K1 is the coefficient of the environment, choose K ¬ 1 = 1, CADIVI cableK2 is the coefficient of the cables laid in the grooves. Because the cable placed in the trench investigation PL VI. 11 (TL 2) select K2 = 0.90.So the cable cross-section is chosen according to the conditions of K2. Icp > IttThe current calculation is:
