Product Description
NYBY/NAYBY Power Cable: Product Description and Specifications
The NYCY Power Cable serves as a versatile low voltage solution featuring PVC insulation, a PVC sheath, and a distinctive concentric copper conductor. Specifically, while the NYCY model utilizes copper main conductors, the NAYCY variant offers an aluminium alternative.
In addition, the helically applied concentric copper wires and tape act as a combined neutral and protective conductor. This design also provides essential functional screening.
Finally, you can deploy these cables effectively in industrial power distribution, building supply connections, and underground networks. We ensure they comply with major standards such as IEC 60502-1.

Production Processes Of Power Cable
To ensure superior quality, JOCA operates fully digitalized and automated production lines for power cables. Specifically, this comprehensive workflow covers conductor stranding, insulation extrusion, metallic screening, and final sheathing. Moreover, intelligent systems actively monitor each stage to ensure stable performance and consistent product quality. In addition, the factory utilizes advanced testing facilities, such as partial discharge testing, tensile testing, and spark testing. Consequently, these rigorous measures guarantee that every delivered cable strictly meets international standards.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: What is the actual function of the concentric copper layer (Ceander)?
A: It serves a dual purpose. First, it acts as the PE or PEN conductor (Protective Earth/Neutral). Second, because it wraps around the cores, it provides effective screening against electromagnetic interference (EMC). This is crucial if you are running power near sensitive data lines or control systems.
Q: NYCY vs. NAYCY: Which one should I specify?
A: It’s strictly a choice of main conductor material. NYCY is solid Copper (expensive, high conductivity). NAYCY uses Aluminum for the main phases (cheaper, lighter), but keeps the concentric screen in Copper. If budget is tight and the cable run is long, NAYCY is the standard engineering choice.
Q: What is the voltage rating?
A: These are standard low-voltage cables rated for 0.6/1 kV. They are manufactured strictly to DIN VDE 0276-603 and IEC 60502-1 specifications.
Q: Can I use these underground?
A: Yes. They are designed for fixed installation indoors, outdoors, in concrete, and directly underground. The concentric conductor actually adds a layer of safety—if someone accidentally digs into the cable, the tool hits the earth screen first, tripping the breaker before hitting a live phase.
Q: Why choose NYCY over standard NYY cables?
A: Two words: EMC Protection. If you are powering VFDs (Variable Frequency Drives) or equipment in a “noisy” electrical environment (like a data center or automated factory), standard NYY won’t stop the noise. NYCY keeps the interference contained.
Q: What are the temperature constraints?
A: Keep in mind these are PVC insulated cables. Your maximum continuous operating temperature is 70°C. If you have a high-heat application or need to push maximum ampacity, you should look at N2XCY (the XLPE version) instead.
Q: Is installation difficult regarding bending radius?
A: They are stiffer than standard cables due to the concentric layer and the helix tape. You need to respect a bending radius of at least 12x to 15x the cable diameter (single-core vs multi-core) to avoid damaging the copper screen during installation.
Q: How do I get a technical proposal or quote?
A: Just email us your Cable Schedule. We need to know: Main conductor material (Cu or Al), cross-section (e.g., 4×95/50), and total length. We’ll verify the screen cross-section requirements and send you a formal quote ASAP.
