0.6/1kV NYFGbY Cable

What is NYFGbY Cable?

NYFGbY Cable is a 0.6/1kV Class 2 stranded copper PVC insulated double-armoured power cable manufactured in accordance with IEC 60502-1, VDE 0271, and IS 1516.1 standards. It is designed specifically for power distribution in harsh operating environments where standard unarmoured or light-armoured cables could fail due to physical impact, ground settling, or excessive pulling tension.

The construction combines stranded plain copper conductors, high-grade PVC insulation, an extruded PVC filler, galvanized flat steel wire armour (SWA), a counter-helical galvanized steel tape, and a tough black PVC outer sheath. By using flat steel wires rather than round wires, the cable distributes crushing forces over a wider surface area while maintaining significant tensile strength, ensuring uninterrupted electrical performance across utility and industrial networks.

NYFGbY Cable Construction

Conductor

Class 2 stranded plain copper conductor ensuring high conductivity and flexibility during installation.

Insulation

PVC (Polyvinyl Chloride) compound rated for continuous operating temperatures up to +70°C.

Filler Layer

Extruded PVC (Polyvinyl Chloride) forming a solid, circular bed around the insulated core assembly.

Primary Armour (Armour 1)

Galvanised flat steel wires (SWA) arranged to withstand heavy longitudinal pulling forces.

Secondary Armour (Armour 2)

Galvanised steel tape counter-wrapped to lock the flat wires and maximize transverse crushing resistance.

Outer Sheath

Flame-retardant black PVC (Polyvinyl Chloride) compliant with EN 60332-1 flame propagation limits.

Core Identification

2 core: Blue, Brown; 3 core: Brown, Black, Grey; 4 core: Blue, Brown, Black, Grey; 5 core: Blue, Brown, Black, Grey, Black.

Applications

The double-armoured construction of NYFGbY makes it ideal for low-voltage power transmission across demanding civil, municipal, and industrial projects. Typical application environments include:

Underground Direct Burial: Laid directly in soil, rocky backfill, or utility trenches where high physical compaction, vehicle surface weights, or ground shifting occur.
Industrial Ducting & Trunking: Installed inside subterranean concrete ducts, industrial cable trunking, and open wire trays subject to continuous physical compulsion.
Fixed Indoor & Outdoor Power Supply: Routed along heavy manufacturing plants, power generation stations, and municipal infrastructure where increased mechanical protection is mandatory.

Frequently Asked Questions

Q: What is the primary difference between NYFGbY and N2XFGbY cables?
A: NYFGbY features PVC insulation with a maximum operating temperature of +70°C, whereas N2XFGbY utilizes XLPE insulation rated for higher thermal loads up to +90°C.

Q: Why does NYFGbY use flat steel wires instead of round steel wire armour?
A: Galvanized flat steel wires provide a broader contact surface that distributes external crushing forces more effectively while giving superior longitudinal strength during heavy pulling.

Q: Is NYFGbY cable suitable for direct burial in the ground?
A: Yes, NYFGbY is specifically designed for direct burial in soil, as well as installation indoors, outdoors, and in cable trunking where harsh conditions exist.

Q: What payment terms does Huadong Cable Group accept for international orders?
A: We accept Telegraphic Transfer (T/T) and Irrevocable Letter of Credit (L/C) at sight for international B2B transactions.
