UTP means Unshielded Twisted Pair, i.e. unshielded and unscreened. Whether data transmission will work well with this cable and whether a shielded cable would be better is a question that cannot be answered easily. It depends on what happens on the 5x2.5mm2 and how the equipotential bonding of the end devices is. Long story short, I would try it with exactly this network cable. Then I would lay another wire/tape and leave it. Then it would be easier to run another data cable. Technically much better would be to use a fibre optic cable for data transmission. Hope it helps
