Product overview

(N)GRDGOEU Festoon Cable for Power, Control and Bus Circuits

(N)GRDGOEU-J/-O is a 0.6/1 kV flexible round festoon cable family for moving power and control connections on cranes, hoists, material-handling systems, transport equipment and machine tools. Buyers may also encounter the designation as NGRDGOEU or NGRDGÖU; the J and O suffixes must still be matched to the required protective-conductor arrangement.

This page keeps the verified single-core, split-earth power, 4-core, 5-core, multicore control and screened-pair bus configurations together. That lets a procurement engineer compare an exact variant such as (N)GRDGOEU-O 1 × 70 mm² or (N)GRDGOEU-J 30 × 2.5 mm² without creating thin size-only pages.

Use this family for: supported festoon loops and flexible machine connections subject to frequent bending.
Choose the suffix carefully: J identifies a construction with a green/yellow protective conductor; O identifies a construction without it.
Confirm before ordering: circuit function, exact core arrangement, cable support, bend radius, travel speed and termination layout.
Screening: individually screened cores or pairs are available only in the source-listed bus configurations; an overall-screened drive cable is a different model family.

Browse the Port & Festoon Cable range or review the crane cable selection guide when the movement method or EMC requirement is not yet fixed.

Construction

(N)GRDGOEU Cable Construction

The (N)GRDGOEU festoon cable uses a round, flexible rubber construction for repeated movement. The exact core lay-up changes with the selected power, control or bus configuration.

(N)GRDGOEU cable cross-section showing round festoon construction — Round (N)GRDGOEU cable cross-section; the final core and screen arrangement follows the selected configuration.

Verified (N)GRDGOEU construction
Element	Construction	Selection relevance
Conductor	Bare electrolytic copper, finely stranded, class 5	Supports flexible festoon and moving-machine connections.
Insulation	High-grade EPR compound, at least 3GI3	Electrical insulation for the verified 0.6/1 kV family.
Core identification	Light-coloured insulation with black numbering; protective conductor green/yellow	Match J or O suffix and terminal schedule before manufacture.
Individual screen where specified	Tinned-copper wire braid; at least 60% coverage for individually screened cores and at least 80% for twisted screened pairs	Applies only to source-listed screened core/pair configurations, not every variant.
Core arrangement	Laid up in a maximum of three layers	Maintains a round cable profile across multicore configurations.
Inner sheath	EPR rubber compound GM1b, black	Provides a bedding layer beneath the outer sheath.
Outer sheath	PCP-based rubber compound, at least 5GM3, black	Source-listed for outdoor and industrial festoon duty.

Applications

(N)GRDGOEU Festoon Cable Applications

(N)GRDGOEU-J/-O is used for flexible low-voltage power and control connections on festoon systems and moving machine parts where the cable is supported in loops and bends repeatedly during operation.

(N)GRDGOEU round festoon cable application on a port crane system — Typical crane festoon environment; final cable selection depends on the trolley geometry and operating duty.

Gantry, hall and container-crane festoon systems
Hoists, lifting equipment and trolley power supplies
Rack and general material-handling equipment
Transport systems and movable machine-tool connections
Multicore festoon control circuits and screened-pair bus routes listed in the Specifications tab

Selection boundaries

Confirm that the cable will operate in a supported festoon arrangement. Reeling onto a powered drum, unsupported vertical travel or continuous torsion can require a different construction. Where the route needs an overall copper screen for a frequency-converter motor supply, review the (N)GRDGCGOEU-J screened festoon cable. Provide the trolley type, loop depth, travel length, speed, acceleration, bend radius and termination arrangement for engineering review.

Specifications

(N)GRDGOEU-J/-O Specifications and Exact Sizes

The model is also searched as NGRDGOEU and NGRDGÖU. Each row below uses the official (N)GRDGOEU-J or (N)GRDGOEU-O designation plus the verified configuration, so buyers can identify the exact orderable variant. German catalogue notation may use G for a J-type configuration, for example 30 G 2.5; the source table below retains the core-count format.
