Product Overview

NYBY Cable is a 0.6/1kV PVC-insulated power cable with double galvanized steel tape armor and PVC sheath. VDE naming: N = standard type, Y = PVC insulation, B = steel tape armor, Y = PVC sheath. NYBY is the PVC-insulated counterpart to the XLPE-insulated N2XBY family — delivering the same mechanical protection at a lower cost point. PVC insulation is rated 70°C (vs 90°C for XLPE), with proportionally thicker insulation walls to achieve the same voltage rating. NYBY is the most economical armored cable option for installations where the higher current capacity of XLPE insulation is not required.

PVC vs XLPE Insulation in Armored Cables

Property	NYBY (PVC Insulation)	N2XBY (XLPE Insulation)
Insulation Material	PVC	XLPE (cross-linked polyethylene)
Max. Operating Temperature	70°C	90°C
Short-Circuit Temperature	160°C (max 5s)	250°C (max 5s)
Insulation Thickness (10mm²)	1.0mm	0.7mm
Current Capacity (same section)	~20-30% lower	Reference
Cost	Lower — standard PVC compound	Higher — XLPE compound

Selection rule: Choose NYBY (PVC) when building codes permit PVC insulation and the cost saving outweighs the slightly lower current capacity. For high-temperature environments or where maximizing ampacity within a given duct size is critical, choose N2XBY (XLPE).

Cable Construction

Copper Conductor

Class 1 (solid) or Class 2 (stranded) copper. Plain annealed per EN 60228.

PVC Insulation (Y)

PVC compound, rated 70°C continuous. Thicker than XLPE for equivalent voltage rating.

Core Assembly

Laid-up cores with non-hygroscopic filler, binder tape for circular cross-section, PVC inner bedding.

Steel Tape Armor (B)

Double galvanized steel tape, helically applied with overlap. 0.2mm for ≤70mm², 0.5mm for ≥95mm².

PVC Outer Sheath (Y)

PVC compound 5V-90, black. Standard industrial-grade sheath with good oil and UV resistance.

Installation Flexibility

Bend radius: 15 × D (single-core), 12 × D (multi-core). Min installation temperature: -5°C.

Technical Characteristics

Rated Voltage	0.6/1kV
Max. Conductor Temperature	70°C (continuous), 160°C (short-circuit)
Test Voltage	4 kV AC
Min. Bending Radius	15 × D (single-core), 12 × D (multi-core)
Min. Installation Temperature	-5°C
Armor Type	Non-magnetic steel tape (0.2mm or 0.5mm)
