Product Overview
NAYBY Cable is a 0.6/1kV PVC-insulated steel tape armoured PVC-sheathed power cable with aluminium conductor, manufactured to the German VDE standard DIN VDE 0276-603. Naming follows VDE convention: N = standard type, A = aluminium conductor, Y = PVC insulation, B = steel tape armour (Bewehrung), Y = PVC outer sheath. It is the aluminium-conductor counterpart of the copper NYBY — identical Al/PVC/STA/PVC construction with ~30% weight reduction and lower material cost. The Chinese GB/T equivalent is VLV22. NAYBY is widely specified for underground power distribution, industrial feeder circuits, and building installations where aluminium conductor economics are prioritised under VDE-certified construction.
Outer Sheath — Black PVC, flame retardant
Steel Tape Armour — Double galvanized, helically applied
PVC Bedding — Light blue extruded separation sheath
PVC Insulation — 70°C, VDE 0276 colour coded
Aluminium Conductor — Class 2 stranded per IEC 60228
Aluminium Conductor
Class 2 stranded per IEC 60228. Solid for ≤4mm², stranded for ≥6mm². 61% IACS conductivity at ~50% weight of equivalent copper.
PVC Insulation
70°C continuous, 160°C short-circuit (max 5s). VDE 0276-603 colour coded: Brown/Black/Grey/Blue + Green/Yellow for earth.
PVC Bedding
Light blue extruded separation sheath between cores and armour. Prevents PVC insulation abrasion from steel tape edges during bending.
Steel Tape Armour
Double galvanized steel tape, helically applied. 0.2mm for ≤35mm², 0.5mm for ≥50mm². Provides mechanical protection for direct burial.
PVC Outer Sheath
Black PVC compound 5V-90. Flame retardant per IEC 60332-1. UV and moisture resistant for outdoor and underground use.
Economic Armoured
Aluminium conductor + PVC insulation offers the lowest-cost armoured cable solution. ~30% lighter and ~50% cheaper conductor vs copper NYBY.
