What is NYRUZY cable?
NYRUZY: covered tube wire (umhüllter Rohrdraht), PVC insulated copper cores under a common covering, a folded zinc tape sheath and a thermoplastic outer covering, 500 V. Rating: 500 V; fixed laying in dry and damp rooms, on and under plaster and outdoors; conductor at most 70 °C. Standard: DIN 47707:1970-11 (Umhüllte Rohrdrähte NYRUZY: use, dimensions, weights; withdrawn, a decoder reading only, not a current standard).
Maximum outer diameter d2 for 2 / 3 / 4 / 5 cores (mm; negative tolerances 2 to 3,8 mm): 1,5 mm² 10,2 / 10,6 / 11,5 / 12,5; 2,5 11,5 / 12 / 13 / 14; 4 13 / 13,5 / 15 / 17; 6 14 / 15 / 17 / 18,5; 10 17 / 18 / 20,5 / 22,5; 16 21,5 / 23 / 25 / 27,5; 25 26 / 27,5 / 30 / none. Conductor diameter d1 at most 1,4 / 1,8 / 2,3 / 2,8 / 3,6 / 5,2 / 6,5 mm; one wire to 10 mm², seven from 16 mm². Bending radius at least 6 d2 (a guide value for laying). Examples NYRUZY-J 3x6 (with a green-and-yellow core), NYRUZY-O 3x6. The zinc sheath has no material code in the decoder; the reading draws it as a metal sheath.
