The underground cable can be also great to use as an external cable - we have rescheduled shortly after a connection via garage appeared less complicated than to dig across the whole garden. Especially since the recommendation when underground cables also reads, 60-80cm deep digging to fill the trench with sand to lay the cable in a pipe in the trench, cover again with sand and then to put even a signal band about. So the professional. For home use, it is enough probably to bury the cable under sod depth. Nevertheless, quite as hemdsärmelig I wanted then did not embarrassed and I opted for the overland option. So also the sandbox daughter is not plundered.
The cable itself is robust and makes a high impression. It consists of a casing made of a thermoplastic polyethylene and solid wires inside (no wires). The disadvantage of this is that flexibility; a 90-degree bend is approximately 5cm "long" until the bend has been made, if you do not want to bend the cable. The diameter is about 11mm, so I had to partly provided my little cable holders with longer nails, to force the cable around the bend.
If you want to deal in more detail with the label NYY-J, just google for "lines according to German standards" - the first Wikipedia link titled "type code of lines" brings disruption.
The seller "trade-Hohmann" shipped by the way as fast as Amazon Prime: ordered afternoon, the next day the cable was there. Excellent!
