Single Core (Shielded) LV Cabling for Audio Equipment

Adrian B
Hi All


Quick question regarding suitable cabling for LV supplies to Audio equipment.....

I have a client (Sound Studio Designer) who is insisting on the LV power cabling to serve many different types of Audio equipment being shielded.  Firstly, I have never specified anything of the sort previously, normally specifying 6491 or 6242 etc., so is there something out there that is suitable?  Secondly, has anyone had any experience in this type of installation, and if so, what are the thoughts on single core or multi core cabling with shielding?  I personally would have thought that shielded singles would be the preference, but what do I know, I am quite obviously not a specialist in this field.


Any advice/ help would be hugely appreciated as always.


Thanks

    I am familiar with EBB installations (equipotential bonding busbar), as used within Healthcare installations such as MRI's, CT Scanners etc., so can I take it that this is what you are suggesting (or very similar) is common practice in this instance?



    It's the approach that BS EN 50310 takes (as Graham mentioned earlier)  - there are a number of methods - bars, or rings that go right around the building (or room) or just lots of small connections - which works best can depend on a lot of factors not least the physical layout of the system that needs protection (e.g. whether it's a single room, or a whole floor or a building of many floors; and whether the equipment is tightly packed, or scattered in several small groups or thinly spaced)
