4 RATED VOLT AGE The rated volt age of ca bles is marked Uo/U, where: - U o = rated volt age be tween the con duc tor and earth or me tal lic screen - U = rated volt age be tween con duc tors. DI RECT CUR RENT RE SIS TANCE OF CON DUC TORS The cata logue lists for each ca ble, the maxi mum di rect cur rent re sis tance val ues for the con duc tor at a tem pera ture of +20 °C, per mit ted by the con struc tion stan dard.The cur rent in a con duc tor heats up the con duc tor. The rise in tem pera ture in creases the con duc tor’s re sis tance.
