When it comes to supplying power safely and reliably in industrial, commercial, or utility installations, selecting the right cable is critical. Among the wide range of medium-voltage cables, the NYFGY 3.6/6kV PVC Insulated SWA Armored Power Cable stands out for its versatility, durability, and compliance with international standards. But what exactly makes NYFGY armored cable suitable for fixed, buried, or even immersed installations? How does it compare with similar cables in the market?

Where Can NYFGY 3.6/6kV Cable Be Applied?

The cable’s combination of PVC insulation, SWA armor, and flame retardant properties makes it suitable for a wide range of installations:

  • Fixed installations in industrial plants: Power distribution to motors, switchgear, and control panels.

  • Buried installations: Directly in the ground without additional mechanical protection, compliant with local regulations.

  • Immersed installations: In water or damp environments, offering robust insulation and protection.

  • Commercial and utility networks: Hospitals, hotels, schools, and high-rise buildings requiring reliable medium-voltage supply.

  • Harsh environments: Where chemical, moisture, or mechanical stresses may affect cable integrity.

In Indonesia, NYFGY cables have been successfully used in industrial complexes in Jakarta and Surabaya, where they deliver power to fixed installations buried underground, providing a combination of safety, durability, and flame retardancy.

Frequently Asked Questions (FAQ) About NYFGY 3.6/6kV

Can NYFGY cables be used for outdoor installations?

Yes, the cable’s PVC sheath and SWA armor allow it to be installed outdoors. While UV exposure should be considered, PVC provides sufficient protection for general outdoor environments.

Is NYFGY suitable for high-moisture areas?

Absolutely. NYFGY is designed for buried or immersed installations, offering moisture resistance without the need for additional mechanical protection.

How does NYFGY compare to unarmored PVC cables?

Armored cables like NYFGY provide mechanical protection, flame retardancy, and suitability for buried installations, whereas unarmored PVC cables are limited to indoor or ducted installations and are more susceptible to mechanical damage.

What are the advantages of copper conductors in NYFGY?

Copper offers high conductivity, reliability, and ductility, ensuring efficient power transmission and resistance to breakage, especially under bending or pulling during installation.

Can NYFGY cables handle short-circuit conditions?

The cable’s maximum conductor temperature of 70°C ensures safe operation under normal load. For short-circuit events, appropriate protections like fuses or circuit breakers should be installed.

Are there real-world case studies of NYFGY usage in Indonesia?

Yes. In a power distribution project in Surabaya, NYFGY cables were used for underground power lines in an industrial plant. The armored design allowed direct burial, reducing construction costs, and the PVC sheath maintained insulation integrity in wet soil conditions.
