As a part of a project I have noticed that some are using this cable for powering a smartphone on the top of a 120 meter mast. This cable goes from the ground all the way to the mast to power the AC/DC adapter of a smartphone in a box.
The cabe is defined as "Industrial Cable Screened". And it has a shield not an earth wire. Although according to its specs it can pass uto 2.5A current, Im not sure whether it is okay to use as a mains cable.
My questions are:
1-) Is it okay to use such cable instead of a 3-wire(phase neutral earth) AC mains power cable outdoors?
2-) The cable in the link has a shield. Does the shield have any advantage to use as an AC mains cable in this case?
Im wondering what were they thinking when using this cable instead of a typical AC mains power cable. Or maybe just a wrong thinking?
(I hesitated to ask here but I thought maybe some has experience on the matter.)
