C-H, Over here, Neutral-Screened is invariably used as a medium for our U/G services. It saves having to muck around with putting a length of TPS in conduit, which in turn has to be de-rated. Sorry but I can't get a pic of a piece of N/Screened at the moment. Over here, this cable has an outer sheath of 3.2mm thick PVC and it can be buried direct, without further Mechanical protection, provided that it is buried at Regulation depth (600mm).
