[QUOTE="Sidewinder, post: 490194, member: 9512"] The SWA armour should be earthed, thus, should not give issue with “noise” from the mains, but, this is not guaranteed, and depends on the current, and the actual lay of the armour in the cable. The “lay” depends on the way the cable is made, wound, unwound, & how many times this is done, and how it is installed in the duct. You can get SWA Cat5E and I have installed this in ducts with (relatively) high current 3ph mains SWA without issue, and, over the distances you are looking at. Whatever you do, do NOT use “normal” Cat5E, use at least duct grade. [/QUOTE]
