tank/hv earth electrode and nearby concrete pad with mounted lighting column

psychicwarrior
Hello - good day to all !


Any experience/experiences that might provide a few tips/watch out fors etc, most gratefully received.


Contemplating the run of buried SWA cabled over 100m for outdoor lighting (and electric gates) passing by a pole mounted transformer, where it's been confirmed by the distributor that there is a Tank/HV earth electrode setup  at the pole. Whilst explaining this was not a rigid rule (more a guide and just as well as it shuts off the only feasible route), it was suggested best [in this case] to stay out of a 9m radius if burying cables - but the situation would be helped if this had to be compromised, by running the cabling in ducting/conduit when in the ground.


What are opinions on the siting of concrete pads with threaded rod to secure [conductive] column lighting in this context; this would seem a more serious concern within the 9m advice, is it a no-no, is there anything that can be done to mitigate (aside to using all non-conducting materials), or is it a non-issue (I feel not) ? 


I have no experience of such a long distance, but any tips and advice on pulling SWA along duct for over 100m would be uiseful too :-)   \\m/


Thank you all

    Thanks all for the input. Much appreciated.


    I think you might all see that I'd got to the point that putting a lamp post as described within the 'hot zone' (using words above) was, all things considered, something to be avoided if possible.


    Burried cable already mentioned as going in plastic duct or as suitable.


    I will have a look at the fibreglass cladding is an option to bear in mind (thanks mapj).


    The property owner, will no surprise be set on any aesthetics of lamp posts they want so will try to work with that of course.


    Will have a final check with distributor contact and just get a final review.


    I think best be safe than be risky is how I felt when I first posted and all the comments have been useful.


    Thanks again :)
