<strong>Planning</strong> principles2.2 Busbar trunking system planning2.2.3 A comparison of busbar trunking systems and cable trunkingComparison of featuresFeature Busbar trunking unit Cable trunkingTTA x -Mechanical safety High LowFire load Low HighThermal characteristics Ambient temperature compliant <strong>with</strong> DIN In accordance <strong>with</strong>EN 60439-1 and -2DIN 57298-4, Chap. 5.3.3.1/max. +40°C and +35°C average over DIN VDE 0298-4/2.88,24 hourscable loads assume +30°C.Network topologyProtective devices for loadsTransparent (line topology <strong>with</strong> loadfeeders connected in series via tap-offunits)In the tap-off unit: facilitating direct andimmediately traceable assignment to loadlocally.Significant cable cluster at feeding point dueto point-to-point power supply to loads fromcentral power distribution systemCentrally in the distribution board: this meansthat assignment to the load cannot beverified directly. You have to rely on thecable and load being labelled correctly.Space requirements Low High, since correspondingly large distributionboards are needed. Laying criteria(clustering, laying method, current carryingcapacity, etc.) have to be taken into account.Retrofitting in the event ofchanges to load feeders<strong>Planning</strong> and configurationDimensioning (current, voltagedrop, neutralisation conditions)Highly flexible thanks to tap-off points inthe trunking units and large number ofdifferent tap-off unitsQuick and easy using computer-assistedplanning toolsComplexTime-consuming and expensive. Additionalcables need to be laid from the distributionboard to the load.Configuration is time-consuming andcomplex (distribution board and cabledimensioning, cable diagrams, etc.)Very complexTroubleshooting expenditure Low HighFireproof barrier Type-tested, factory-built Dependent upon installation quality on siteFunctional enduranceFunctional endurance tested toDependent upon installation quality on siteDIN 4102-12Electromagnetic interference Low due to sheet steel encapsulation and Relatively high for standard cablesconductor configurationInstallationFew installation accessories and tools,short installation timesExtensive installation accessories andnumerous tools, long installation timesWeightHalogen-free, PVC-freeWeighs up to 1/3 of comparable cableweightAll tap-off units are halogen-free andPVC-free.Up to 3 times the weight of the busbartrunking systemStandard cables are not halogen-free andPVC-free.<strong>Planning</strong> <strong>with</strong> <strong>SIVACON</strong> 8 <strong>PS</strong>26 <strong>Planning</strong> Manual, 10/2007, A5E01541101-01
