NGFLGOEU cable is a 300/500 V flat rubber power and control cable for festoon trolley systems and movable machine parts. Its parallel-core geometry is designed for frequent bending in one plane, with EPR insulation, a black chloroprene rubber sheath and a documented trolley speed up to 180 m/min.
TEBAOFLEX offers NGFLGOEU flat festoon cable in power, control and selected screened configurations from 1 mm² to 120 mm². Final dimensions, current capacity, bend radius, tensile load and documentation are confirmed against the ordered configuration and installation data before production.

What Is NGFLGOEU Cable Used For?
NGFLGOEU is used where a moving machine needs power or control circuits delivered through a supported festoon system. Common searches include NGFLGOEU flat cable, crane festoon cable, flat rubber cable, festoon trolley cable, overhead crane cable and material handling cable. The flat form keeps the cores in a parallel plane so the cable can form repeatable loops between trolley carriers.
Typical equipment includes overhead bridge cranes, transfer lines, travelling hoists, conveyor systems and other movable machinery with a properly engineered festoon track. The application must keep bending in one plane and support the cable at the trolley saddles. The documented construction is not intended as a reeling cable and should not be substituted for a gantry or reel duty without engineering review.
How Is the NGFLGOEU Flat Rubber Cable Constructed?
| Component | Construction | Engineering relevance |
|---|---|---|
| Conductor | Electrolytic bare copper; Class 6 up to 25 mm² and Class 5 from 35 mm² | Provides flexibility for repeated festoon movement while supporting larger power sizes. |
| Insulation | EPR rubber compound 3GI3 | Electrical insulation for the documented voltage and temperature range. |
| Core identification | Up to 5 cores: green/yellow, black, blue, brown and grey; over 5 cores: black with white numbers | Supports installation and circuit identification. |
| Individual screen | Tinned copper braid, approximately 60% coverage; approximately 80% for twisted or shielded pairs | Available in the documented C and shielded-pair configurations where circuit screening is required. |
| Core arrangement | Cores in parallel; more than 12 cores arranged in parallel bundles | Creates the flat profile and controls one-plane bending. |
| Outer sheath | Black CR rubber compound 5GM3 | Provides the outer mechanical and environmental protection. |

How Do You Select the Correct Flat Festoon Cable?
| RFQ input | Why it matters |
|---|---|
| Power and control circuits | Determines the core count, conductor sizes and whether screened pairs or individually screened cores are required. |
| Travel distance and speed | Allows trolley spacing, loop depth, cable reserve and the stated 180 m/min speed limit to be checked. |
| Bending plane and motion | Confirms that the installation is a supported festoon system with bending in one plane rather than reeling or gantry motion. |
| Trolley saddle geometry | Must suit the finished cable width, height, minimum bend radius and permissible tensile force. |
| Ambient and exposure | Confirms temperature, indoor or outdoor use, humidity, water, UV, ozone, oil and any chemical exposure. |
| Electrical design | Defines voltage, current, voltage drop, short-circuit duty and conductor temperature for the selected size. |
| Documentation | Identifies the required drawings, tests, inspection records, marking and project-specific approvals before production. |
Installation Limits and Engineering Notes
- Use NGFLGOEU in a supported festoon trolley system with bending in one plane only.
- Do not use this construction as a random-winding, monospiral, spring reel or motorized reeling cable.
- Do not treat the 180 m/min reference as a universal system guarantee; trolley spacing, acceleration, loop depth and installation geometry remain part of the complete design.
- Observe the size-specific minimum bend radius and maximum tensile force in the dimensional table.
- Protect the cable from twisting, side pull, sharp trolley edges, crushing and uncontrolled impact.
- Confirm current capacity and short-circuit duty for the actual ambient temperature, grouping, ventilation and duty cycle.
