ELECTRICAL CHARACTERISTICS
The modern industrial environment demands reliable, flexible, and safe power transmission solutions. Among these, the (N)GFLCGÖU Screened Flat Festoon Cable 300/500V stands out as a high-performance cable designed specifically for lifts, cranes, floor conveyor systems, and festoon applications. But what exactly makes this cable suitable for such demanding uses, and how does it compare to other festoon cables?
What Is the (N)GFLCGÖU Flat Festoon Cable and Why Is It Flat?
The (N)GFLCGÖU is a screened flat festoon cable, meaning its conductors are arranged side by side rather than twisted or bundled. This flat geometry allows the cable to occupy minimal space while offering a reduced bending radius, making it ideal for applications where compact installation is essential.
Flat structure advantage: Minimizes space usage and enables smooth movement on festoon systems.
Screening: Tinned copper wire braiding protects against electromagnetic interference (EMI), ensuring reliable signal and power integrity in sensitive industrial equipment.
Flexibility: Despite its compact design, it handles flexing and mobile movement within its rated limits.
What Are the Technical Specifications of (N)GFLCGÖU Cables?
These cables are built to meet international standards such as VDE, DIN, IEC, and HD/EN/IEC, ensuring global compliance for industrial applications. Key specifications include:
Voltage Rating (Uo/U): 300/500V
Temperature Rating:
Flexed: -50°C to +90°C
Mobile: -30°C to +90°C
Maximum Conductor Operating Temperature: 90°C
Maximum Short-Circuit Temperature: 250°C
Minimum Bending Radius:
Fixed: 5 × overall diameter
Moving: 10 × overall diameter

Indonesia:
In Jakarta’s largest port, (N)GFLCGÖU cables have been deployed in overhead crane systems. Engineers reported reduced downtime and longer cable service life compared to older PVC-insulated flat cables, thanks to CR sheath chemical resistance and EPR insulation flexibility.
Frequently Asked Questions About (N)GFLCGÖU Flat Festoon Cables
Q1: Can (N)GFLCGÖU cables be used in outdoor applications?
Yes, the CR sheath offers UV and weather resistance, but ensure ambient temperature stays within rated limits.
Q2: How does it compare to round festoon cables?
Feature | Flat (N)GFLCGÖU | Round Festoon Cable |
|---|---|---|
Space-saving | ✅ Excellent | ❌ Limited |
Bending radius | Small | Larger |
EMI protection | ✅ Braided screen | Optional |
Flexing endurance | High | Moderate |
Q3: What is the maximum current for a 4-core 50 mm² cable?
The permissible current rating is 192 A under standard installation conditions.
Q4: Are these cables suitable for torsional stress?
No. They are designed for flexing along one plane and should not be twisted.
Q5: How do I select the correct core size?
Consider load current, voltage drop, flexing frequency, and installation space. For high-speed conveyor systems, higher cross-section reduces voltage drop.
Q6: Can these cables handle chemical exposure?
Yes, the CR sheath is resistant to oils, greases, aliphatic hydrocarbons, and some acids.
