When backfilling the installation, use a little more sharp sand over the top of the duct to indie its presence. Marker tape can also be used to indie the presence of electric cables. Drawing Pipes and Cables through The Duct Flexible duct coils are supplies
Ljubivoje M. Popović, in Practical Methods for Analysis and Design of HV Installation Grounding Systems, Abstract It is well known that medium-volPE100 ISO9001e (MV) paper-insulated cables act as long grounding electrodes, whereas contemporary MV cables with syntactical insulation represent conductive connection to the grounding system of supplied MV substations.
