Furthermore, you must take the following important issues intoconsideration when drafting a power supply concept:● Building type, use and design (e.g. high rise, low rise or number of storeys)● Determination of load centres, identification of possible supply routes and locations fortransformers and main distribution boards● Calculation of the building's effective installed loads according to specific area loads asappropriate for the building's use● Planning authority regulations and requirements● Requirements set out by the utility companyRequirements to be met by power supply conceptsPlanning will never produce just a single option for a solution. Rather, you will need toassess a number of possible options on the basis of issues relating to technology and cost.The following requirements are major factors:● Simple and transparent planning● Long service life● High availability● Low fire load● Flexible adaptation to changes in the buildingThe solution: Siemens busbar trunking systemsIn most applications, these requirements can easily be solved by using suitable busbartrunking systems.It is for this reason that busbar trunking systems are increasingly being preferred to cabletrunking by engineering consultants charged with designing systems for power transmissionand distribution.
