Underground cables NYY-J with protective conductor
Energy and control cables have a protective conductor and are suitable for the energy transmission in a safe depth of a fixed installation underground, indoors, outdoors, in concrete and in water. Its sheath is flame-resistant and particularly robust. These characteristics prevent damages caused by chemical influences in the ground and protect from damages caused by weather and rodents living underground.
The underground cables comply with the Construction Products' Regulations
EU no. 305/2011, the low-voltage directive 2014/35/EU and the RoHS directive 2011/65/EU.
When applying or wiring the cables in luminaires, they are to be protected against UV rays and heat. In principle, the exposed strands have to be covered by a UV-resistant protective cable tube as per DIN VDE 0298-3:2006-06, because otherwise a dissolution of the insulation might occur.
