Aluminium/Copper Split Con

AncientMariner
I have been trying to find either a table or current figures for split-con cable where the Live is 25mm2 Aluminium (single core) and both the Neutral (7 strand) and Earth (5 strand) are 16mm2 Copper. This split-con used by Scottish Power in their MANWEB area circa 2002. Google has not been my friend...


I am interested in current ratings for buried in the ground and within a hockey stick (in wall cavity) and the max BS88 fuse that could be used by the DNO to protect - currently an 80 amp.

Thanks.

    I’ll have to check my cable tables later. I am still fairly confident two of your “conductors” nearest to the earths have no copper in them. If you look at the insulation on the phase and compare it to the neutrals, you can see why we usually call it “covered” rather than “insulated”. 


    Regards,


    Alan.
