Planning with SIVACON 8 PS - Siemens

Planning with LDA/LDC4.2 System componentsStructure of the busbar packageAn example a 7-bar system (sectional view) is illustrated below. The positions of theindividual phases and the protective conductor PEN are indicated. You can also see theenclosure profile. Figure 4-2Sectional drawing of a 7-bar systemLD busbar systems are available with aluminium (LDA....) and also copper (LDC....)conductor materials. Due to the conductors’ special surface finishing, trunking units withdifferent conductor materials can be combined. In addition to tinning, aluminium bars arealso coated with a layer of nickel.123Aluminium barNickel layer, tinningMoulded-plastic coating with high heat resistanceLDA busbar systems with aluminium conductors123Copper barTinningMoulded-plastic coating with high heat resistanceLDA busbar systems with copper conductorsPlanning with SIVACON 8 PS108 Planning Manual, 10/2007, A5E01541101-01
