Cable cross-section to be chosen according to the conditions of play allows for hot and check the voltage loss conditions allow.When electric current passes through the cable conductor gets hot, if the temperature is too high the cables can do them damage or reduce the life expectancy. On the other hand the durability of conductive metal being dropped. So the manufacturer determines the temperature allows for each type of cable.Consequently cables must satisfy the following conditions:k. Icp > Ilvmax Of which:Ilvmax is the maximum working voltage of the cable.ICP is the electric current that allows the application to selected cable.k is the coefficient of temperature adjustment. Look up PL 4.21 (TL 1) k = 0.63* Maximum working voltage of TBA's: (A)With Sđm is the power of the transformers provided for a single resource.
