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

    This cable is BS 7870, split concentric, a distribution (DNO) cable. This is used in a "wiring regulations" environment, if it is not recognised in the regs it must be detailed as a "deviation."



    I'd suggest that BS 7671 doesn't have a list of acceptable cable types - although it does (perhaps just for the convenience of the reader) list and provide data for some common types. I think all the cables listed in BS 7671 are for LV use - yet BS 7671 has a much wider scope these days - from SELV door bells to 12V electrics in caravans - yet bell wire isn't listed nor are automotive cables (usually to ISO 6722).


    The fundamental requirement is for all items to comply with an appropriate BS or HD, or in the absence of such a standard to an international standard or appropriate standard of another country. If a cable meets any of those, there's no deviation.


    Of course a cable needs to be suitable for its intended purpose - and just complying with some random BS is no guarantee of that.
