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 ?
