(N)GRDGCGOEU-J Screened Festoon Cable for FC and VFD Drives
(N)GRDGCGOEU-J is a 0.6/1 kV overall-screened round festoon cable for moving power connections on gantry cranes, indoor cranes, material-handling equipment, transport systems and machine tools. Buyers also search the model as NGRDGCGOEU-J and NGRDGCGÖU-J. Its tinned-copper braid surrounds the inner sheath, providing an EMC-oriented construction where motor-power routes can disturb adjacent control or data cables.
The family covers four-core sizes up to 10 mm² and three main-conductor layouts with split protective-earth conductors from 16 mm². TEBAOFLEX can manufacture the listed configurations after the application, cable route and final production drawing have been technically confirmed.
- Best fit: supported festoon loops and flexible motor-supply routes requiring an overall copper screen.
- Confirm the earth layout: four-core construction is used through 10 mm²; larger sizes use three main cores with the protective conductor divided into three parts.
- Check the complete EMC route: screen termination, bonding and gland arrangement affect system performance.
- Choose another cable when: the route involves continuous torsion, powered-drum reeling or an unscreened control circuit.
Compare other options in the Port & Festoon Cable range, or use the crane cable selection guide to distinguish festoon, reeling and spreader duty.
(N)GRDGCGOEU-J Cable Construction
The overall-screened construction combines flexible rubber-insulated power conductors with a copper braid over the inner sheath. This arrangement separates the screen from the individual power cores and provides a continuous EMC layer around the cable assembly.
| Element | Construction | Buyer relevance |
|---|---|---|
| Main conductor | Bare electrolytic copper, finely stranded, class 5 | Flexible conductor construction for repeated festoon bending. |
| Protective-earth conductor | Tinned, extremely finely stranded copper, class FS; green/yellow identification | Confirm the earth cross-section and termination arrangement with the selected size. |
| Insulation | High-grade EPR compound, source-listed as at least GI3 | Rubber insulation for the verified low-voltage construction. |
| Core arrangement | Up to 10 mm²: four-core design. From 16 mm²: three main conductors with the protective conductor split into three parts in the interstices | Prevents a shorthand “3C” enquiry from omitting the required split earth conductors. |
| Inner sheath | Black EPR rubber compound GM1b | Forms the bedding below the overall screen. |
| Overall screen | Tinned-copper wire braid, more than 80% surface coverage; transfer impedance below 100 mΩ/m at frequencies up to 30 MHz | Requires a compatible screen-bonding and gland plan. |
| Outer sheath | Black PCP rubber compound 5GM3 | Source-listed for outdoor and industrial festoon service. |
Applications for (N)GRDGCGOEU-J Screened Festoon Cable
The cable is intended for supported festoon systems exposed to frequent bending and high mechanical stress, particularly where a nearby data or control route could be affected by emissions from the motor-power cable.
- Gantry and hall-crane trolley power systems
- Rack and general material-handling equipment
- Transportation systems and movable machine tools
- Flexible motor power supplies connected to frequency converters
- Festoon routes requiring an overall copper screen for EMC control
Route and EMC checks before ordering
Confirm the trolley system, loop length, available space, supported cable weight, speed, acceleration and minimum bend radius. The screen must be coordinated with the gland, bonding and protective-earth design. Torsional stress is not allowed. For unscreened power, multicore control or screened-pair bus configurations, compare the (N)GRDGOEU-J/-O round festoon cable. For festoon operation, the source specifically advises against using cross-sections above 3 × 50 mm² without application review.
