DIMENSIONS
When it comes to industrial and underground electrical installations, selecting the right cable is crucial for both safety and efficiency. Among the widely used options in Indonesia and other Southeast Asian countries, the NYFGbY 0.6/1kV Armoured PVC Cable stands out for its combination of mechanical protection, flame retardancy, and flexible deployment.
What Is NYFGbY 0.6/1kV Armoured PVC Cable?
The NYFGbY cable is a low-voltage, armoured PVC-insulated power cable designed for demanding environments where mechanical protection and fire safety are essential. With voltage ratings of 0.6/1kV, it is ideal for industrial plants, underground installations, and areas requiring robust electrical distribution networks. It comes in 2 to 5 cores, offering flexibility for various load requirements.
Where Can NYFGbY Cables Be Applied?
NYFGbY is highly versatile and suited for several industrial and underground environments, including:
Underground installations: tunnels, subway systems, and underground factories
Industrial facilities: manufacturing plants, power distribution boards, heavy machinery
Outdoor conduit or trunking: areas requiring mechanical protection against impact or wear
Temporary construction sites: portable installations requiring durable yet flexible cabling
Its flame-retardant PVC sheath and steel armour make it suitable for locations where fire safety and mechanical resilience are critical.
How Does NYFGbY Compare With Other Armoured Cables?
A comparison with typical PVC-insulated cables and unarmoured variants shows NYFGbY’s advantages:
Feature | NYFGbY 0.6/1kV Armoured PVC | Standard PVC Cable | Unarmoured Flexible Cable |
|---|---|---|---|
Mechanical Protection | High (SWA + Steel Tape) | Medium | Low |
Flame Retardant | Yes (EN 60332-1) | Some | Rare |
Suitable for Underground | Yes | Limited | No |
Current Carrying Capacity | High | Moderate | Moderate |
Installation Flexibility | Moderate | High | Very High |
NYFGbY strikes a balance between mechanical robustness, flame safety, and electrical efficiency, making it a preferred choice for heavy-duty applications.
Are There Real-World Use Cases in Indonesia?
Yes, several projects in Indonesia demonstrate NYFGbY’s practical utility:
Jakarta Underground MRT: NYFGbY cables were used for power distribution in tunnels due to their flame-retardant and armoured design.
Industrial Plant in Surabaya: Heavy machinery was powered using 3-core 70mm² NYFGbY cables, ensuring stable power despite harsh mechanical conditions.
Mining Operations in Kalimantan: The 4-core 50mm² cables provided reliable underground power while resisting abrasion and moisture.
These examples highlight NYFGbY’s adaptability across urban, industrial, and subterranean installations.
Frequently Asked Questions
Can NYFGbY cables be used outdoors without conduit?
Yes, but exposure to direct sunlight for long periods may cause UV degradation. Installing in conduits or protective trays is recommended for prolonged outdoor exposure.
What is the maximum short-circuit temperature of NYFGbY cable?
The cable can withstand up to +160°C for short-circuit conditions, which makes it suitable for industrial environments with potential overloads.
How many cores are available for NYFGbY cables?
NYFGbY cables are available in 2, 3, 4, and 5-core configurations, providing options for various power distribution needs.
Can NYFGbY cables be buried directly underground?
Yes, the double-armour construction allows direct burial in most soil conditions. Proper bedding and separation from corrosive substances are advised.
How does NYFGbY compare to unarmoured PVC cables?
While unarmoured cables offer flexibility, NYFGbY provides mechanical protection, flame retardancy, and higher safety for industrial and underground installations.
What is the recommended bending radius for installation?
The minimum bending radius is 12 times the overall diameter, which ensures conductor integrity during installation.
Are there installation guidelines for connecting to switchgear?
Yes, ensure proper crimping, correct torque, and SWA earth bonding for safe and reliable connection. Avoid sharp bends and over-tightening of clamps.
