NYFGY cables, available in medium and low voltage variations, are PVC insulated, armored with flat steel wire, and reinforced with mechanical protection. They are primarily used in laying environments requiring high mechanical strength, such as underground cabling and industrial equipment installation.

NYFGY Cable Features
Enhanced Mechanical Protection: Flat Wire Armor (FWA) provides superior resistance to compression and impact in buried or mechanically stressed environments.
Stable Electrical Performance: High-quality copper conductors ensure excellent conductivity and low power loss.
Durable PVC Insulation: Offers strong resistance to chemical corrosion, oil, moisture, and UV radiation.
Flexible Installation Options: Suitable for direct burial, pipework, tunnel, or fixed installation in industrial plants.
Cost-Effective and Reliable: Mature design compliant with VDE and IEC standards, widely used in industrial projects in Europe and Asia.
Typical Applications
NYFGY cables are suitable for:
Power transmission and distribution in industrial facilities
Underground cable networks
Power plants and substations
Outdoor installations with mechanical stress risks
Fixed cabling in heavy-duty environments
Infrastructure and building projects
For example, underground cable trenches and mechanical installations require additional mechanical protection.
