Application
The abbreviation NYCWY is the type code for the power cables. The individual sections tell you about the material and design of each cable assembly. The main feature is the first letter "N", indicating that it is a standard line with the national VDE standard. NYCWY Cable for Indoors, cable trunking, outdoors and buried in the ground, for power stations, industrial and switchgear as well as for city power networks, if mechanical damage is unlikely.
Meaning of Abbreviations
N = copper conductor
Y= PVC insulation
C= Concentric Conductor
