Soil Thermal Resistivity
Revit Guides
Data Management
Relates to the ability of the soil, in which the cable is installed, to conduct heat energy away from the cable.
The rating factor Cs is applied in cable sizing calculations to account for different soil thermal resistivities.
For cables with Installation Methods 70 to 73, the values of Cs are found in BS7671:2018, Table4B3.
For methods using BICC data Cs has a value of 1.0 for a resistivity of 1.2 K.m/W. For higher resistivities the value of the rating factor will be less than 1,and greater than one for lower resistivities.
Organizational Drivers
The Organizational Driver is a term used to describe the initial component in the information exchange sequence. It represents the steps and actions involved in initiating the exchange process.
