Please advise.
Below is an extract from the Heva cable data base for 4-C XLPE/SWA (LSF) cable.
And below extract from Prysmian data sheet for the same cable.
As can been seen the Heva data utilises a larger CSA of armour, which would give rise to move favourable conditions due to the higher quantity of earth conductor.
Can you please clarify the data used for the SWA armour used in multi core SWA cables for CPC, and advise the implications of the larger CSA of armour.
