Orange Alu Split Con

Martyn
Hi All, 


As per the title I need a 25m ish length of 25mm Orange Alu split con, cant seem to get it from the cable suppliers unless I order to be manufactured with crazy minimum order quantities.


Cant use standard Split con as it’s PVC and I need LSF for an escape route, cable forming part of a BNO replacing a degraded cotton service.


It’s only manufactured in 25 & 35mm apparently, could use either but prefer 25mm.


Anyone with a short length?


Cheers

    For clarification spit con allows a separate neutral and earth (SNE in DNO literature) so presents as TNS. Note that in a building network it is quite likely to still be TNC-s at the origin, so questions like is the main water bond at the origin, and any bonding in the flat supplementary, or is the flat bonding also main bonding, so what size should it be, can cause some dispute. (not as much grief as twin and earth sub-mains though, where the undersize CPC can be a real pain.)

    The construction is the same sort of 'coax cable' as  earthed concentric, but half the outer layer is earth and bare, and the other half is insulated to form the neutral

    Termination requires the neutral strands to be individually stripped and marshalled. Comparing sizes for the same current capacity it is more flexible than SWA, but BS7671 does not consider  it to have an all-encompassing earthed screen or armour so routing  options are a bit less liberal. (again, not as bad as T and E)
