Provide an outer sheathing of galvanised steel wires. This would serve three purposes. Firstly the robust wires would protect the insulated cores from damage. Secondly the steel wires would provide a metallic earth path back to the transformer. And finally, these metal wires would be in contact with the general mass of earth, thereby providing a very low resistance to earth.
How long would the bare metal in contact with earth last before corrosion, even if galvanised? Most "galvanised" products you see these days is barely zinc plated, yet alone hot dipped............
