Can I attach armoured cable to fence?

Yep, they sometimes do. But the point of clipping the cable to the fence (if it happens to be going the right way) rather than, say, shallow dig it is to make it visible and keep it away from potential sources of damage such as digging. The cable would ideally be fixed to, say, the top of the gravel board – ie.
