Planning with LXA/LXC5.2 System componentsStructure of the busbarsThe bars in the LX busbar system are usually tinned and enclosed in a sleeve made ofhighly resistant insulating material. LXA systems feature aluminium conductors and LXCsystems copper conductors. In addition to tinning, aluminium bars are also coated with alayer of nickel.123Aluminium bar (LXA), copper bar (LXC)Layer of nickel, layer of tin (LXA), layer of tin (LXC)Insulating material sleeve with high heat resistanceMounting positions and rated currentThe sandwich construction means that the current carrying capacity of the LX busbar systemis not affected by the mounting position. This guarantees high flexibility for positioning thebusbar runs. Current derating is not required for busbars in edgewise and flat positions onhorizontal busbar runs or on rising main busbars (vertical busbar runs).Horizontal busbar run,edgewise busbarsHorizontal busbar run, flatbusbarsVertical busbar runPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 153
