What is Cable FXG / FXG-D?

FXG is a resilient black neoprene / polychloroprene flat cable family designed for repeated movement in a festoon system. Its parallel side-by-side core arrangement keeps the cable compact in one bending plane, while the 5GM3 abrasion-resistant rubber sheath is intended for higher mechanical stress than a basic indoor festoon cable.

The family covers three practical functions: FXG control, FXG power and FXG-D data / paired conductors. Screened branches are provided for applications that need an engineered EMC path. The supplied record identifies the type families as NGFLGÖU-J/-O, (N)GFLCGÖU-J/-O (EMV) and M(StD)HÖU (EMV).

There is an important rating distinction. The general record states U₀/U = 300/500 V according to DIN VDE and also states suitability for 0.6/1 kV. In the detailed matrices, the FXG control and power branches are marked 0.6/1 kV, while FXG-D data rows are marked 300/500 V. The exact branch, marking and applicable release must therefore be fixed before quotation.

Public product context. The official Conductix-Wampfler webshop lists an FXG screened control cable as a flat rubber cable with 0.6/1 kV maximum voltage, earth and screen, and the order number 131221-F4G1,5C#. That page supports the family terminology; the full matrices below remain transcribed from the supplied FXG / FXG-D record and should be checked against the released Feichun drawing for the actual project.

Electrical, mechanical and environmental envelope

Construction: why the flat form matters in a festoon

The supplied design uses bare copper strands, class 6 according to VDE 0295, with class 5 for cross-sections ≥25 mm². The cores are placed parallel side by side rather than built into a round multi-layer bundle. Core insulation is rubber compound 3GI3; the outer sheath is abrasion-resistant rubber compound 5GM3.

That arrangement is valuable where trolley clearance is limited and the cable repeatedly folds in one plane. The compact package can reduce the required festoon envelope, but it also makes installation discipline more important: a flat cable should not be allowed to roll onto its edge, twist between trolleys or be pinched by a clamp that was designed for round cable.

EMV / EMC is a system property. A screen inside the cable cannot compensate for an interrupted shield termination, an unbonded trolley, a long pigtail or a poorly designed cabinet entry. The screen type, coverage, termination and continuity test belong in the RFQ and inspection plan.

Complete FXG / FXG-D order matrices

These tables preserve the complete conductor schedules, part numbers, d × B geometry, copper index, approximate weight, permitted tensile load and minimum-order field supplied for this article. A dash is retained where the supplied record uses a dash. The screened power 4 G 95C line did not show a minimum-order value in the supplied text, so it is explicitly marked rather than guessed.

How to read d × B

How an experienced engineer selects the correct FXG branch

In a crane or transfer system, the electrical cross-section is only one input. I normally freeze the mechanical duty first, then select the electrical branch, and only after that release the screen and termination details.

Practical comparison inside the family. Unscreened FXG is the compact power/control choice where EMC is not the governing constraint. Screened FXG adds copper braid or foil/wrapped-wire structure and therefore changes geometry, copper index, weight, clamp space and termination work. FXG-D is not a substitute for a power row: it has its own 300/500 V data rating and paired-conductor schedule.

Installation, inspection and failure prevention

Most festoon cable failures are not caused by copper resistance alone. They begin at the mechanical interface: a cable rolls in a trolley, a clamp bites the flat edge, a loop catches on a guide, a screen is terminated with a long pigtail, or acceleration pulls the service loop against the end restraint.

Standards, documentation and Feichun certification capability

The product data references DIN VDE 0298 Part 3 for bending radius, DIN VDE 0298-4 for ampacity, VDE 0295 for conductor class, VDE 0293-308 for identification, EN 60811-404 for oil resistance, IEC 60332-1 for flame retardance and RoHS conformity. These references describe the test or design framework; the final certificate, declaration and test report must match the exact Feichun construction, conductor schedule, sheath compound, screen and market.

For export projects, Feichun Cable can prepare a project-specific technical file and support the applicable certification / approval route, including ATEX, IECEx, VDE, CE, UKCA, EAC and the Russian Fire Safety Certificate. “Certification complete” should be understood as a document package matched to the exact product and destination—not as a generic logo copied from another cable family.

RFQ checklist: information that prevents the wrong flat cable

A good RFQ lets the manufacturer check electrical loading and mechanical life at the same time. Send the following information with the required cable length and replacement reference:

RFQ line example Cable FXG screened control · 4 G 1.5C · 0.6/1 kV · 131221-F4G1,5C# reference festoon travel up to 180 m/min · ambient flexing −30…+85°C · d × B 8.0 × 21.5 mm tinned copper braid, minimum coverage 80% · required length: [project value] termination / trolley drawing: [attach] · destination approval package: [state market]

The line above is a structure for an RFQ, not a replacement for the customer’s actual machine data. Feichun should confirm the final conductor identification, exact print, screen construction, outer dimensions, tests, certificates and accessories before production.
