H07 for overhead supply cable

Looking at replacing an overhead supply cable, support by catenary wire 6m above ground on a farm now renting buildings out to small businesses.

Cable is supplying a small barn that will be used by a family to store and work on stock cars 

Current cable is T+E supported by catenary wire, it's been cut at both ends, unsuitable for outside use, therefore replacing it.

First thought was armoured cable, but then thinking that something like HO7-rn-f might be better. 

        No armoured and surface clipped, so no need for RCD protection on this submain

        Less weight and more flexible, 

Any reason not to use HO7-rn-f ?

  • max unsupported span is less with all-copper of course, but if you have a catenery wire already that is not an issue, and it is certainly done to fly HO7 and similar flexible cables for temporary sites like festivals and army camps,,, Mind you T and E usually lasts a decade or two in the UK as well, its not really sunny enough to degrade very fast.
