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.
Shane,
With respect, I have highlighted to you a substantial error within your software.
it's not an unreasonable assumption to expect the default cable data for SWA PVC and LSF cable to be correct.
And considering the Draka cable for LSF SWA cable is Saffire BS6724 Armoued Cable, and the PVC is BS5467, neither of which is available in the cable selection menu, its not unreasonable for me to ask the software provider which cable I should be using.
I have a number of projects on site with cables sized on the default cable data which are now not suitable, and projects in design which I cant complete because the correct data is not available.
Stuart,
Yes I can appreciate your concern hence we are looking into this in depth for you.

I have reworked the standard XLPE and PVC SWA cable types and created new cables files with the correct armour size, resistance and capacitance in order to move this forward internally. We would expect to see this picked up formally as an update in due course.
Can I have a response please as it appears to have gone quiet with the hope that this can be brushed under the carpet.
Hi Stuart,
We are reviewing this data for accuracy but have some conflicting information to check which is taking some time. Rest assured that once we have fully investigated we will make the appropriate actions. In the meantime it is good to know you have updated your cable data to satisfy your requirements.
