    I want to get some stainless protective sleeving for the signal cables going from my VFD to control box (around 7ft of somewhat hazardous and electrically noisy gap).

    In my mind's eye, I want the sleeving that is on my DRO scale cables - a bit like this:

    But I can't come up with the right search term to find it.

    I absolutely don't want loflex or similar, as I find it really inflexible and hard to work with.

    A stainless steel shower hose might be useful if the bore is big enough when the rubber tube inside is removed , or perhaps the bore of the tube will allow you enough space for all the cables used with it in place .
    Look in Argos they are about £10 for 2 mtrs they can be cut to size and re terminated to fit in small plastic equipment boxes & cases using nut fixed plumbing flanges

    Thanks for that. I did consider this but the cable is only 7mm OD so it seems overkill. Following @Hood's guidance I ended up ordering this off ebay - I reckon the end fittings are worth the extra few quid

    I forget the name of the proper stuff now. They do it in about 10mm OD as I was looking at it for the lathe.

    Sy cable or screened cable is most commonly used for this purpose

    Right the product you are after is strip wound hose i cant find anyone selling it for building cables. So i imagine it's a factory specific thing.

    You could use metal/stainless if you wanted but probably no need - it’s in free air and shouldn’t be that electrically noisy. Vfd aren’t that susceptible to noise unless your using a comms link, even the pot should be ok, use some shielded cable if you want to.

    If you want to run it in flexi conduit the plastic stuff is cheap as chips and will give adequate protection for a lathe or mill, I just used some sy cable on mine.

    I ended up buying the stuff linked above. It's for physical as much as electrical protection.

    Yeah nothing wrong with it - seems a bit overkill to me but I don’t think you could be criticised for making something too safe :thumbup: and it does look the part :thumbup::thumbup:

    Can’t stand the stuff. Much prefer the Lapp control cable, screened on the inside.

    Might be awkward when Mrs Skotl tries to have a shower though :D.

    I just don’t like the clear plastic that discolours and goes brittle.

    That seems brand dependent weve got some extension leads that are maybe 30years old and still together
