FV / FV-D — PVC flat cable for basic-duty festoon systems
FV / FV-D is a practical flat-cable family for festoon installations where the cable travels on a controlled single plane and the priority is a compact, cost-efficient system. The supplied record covers standard PVC power and control cables, screened KYFLCY / KYFLTCY variants, FV-D control-and-data arrangements, and a separate LSOH FV-L section. The important engineering decision is not simply “flat cable or round cable”; it is whether the selected voltage, shield, temperature, fire, geometry and tensile data match the actual festoon system.

1. What FV / FV-D is designed to do
This is a basic-duty festoon family, not a universal moving cable. The supplied application description points to indoor crane trolleys, main indoor-crane power supply, process cranes and storage/retrieval systems. The design is intended for small to medium dynamic loads, a single plane of movement and a compact festoon system where operating temperature does not exceed the stated limit.
Why the flat profile matters
Side-by-side cores produce a controlled d × B geometry. In a festoon, this helps the cable form repeatable loops and share the trolley support width without forcing a round cable into a flat path.

Where it is a good fit
Indoor bridge-crane trolleys, process-crane power, warehouse storage/retrieval machinery and similar guided movement with moderate mechanical stress.

Where caution is required
Outdoor salt exposure, uncontrolled torsion, multi-plane bending, severe impact, high acceleration, continuous reeling or mining trailing duty require a different application review.

What the table really gives you
The part-number rows give finished geometry, copper index, weight and permitted tensile load. The festoon design still needs speed, span, trolley spacing, loop depth, acceleration and end restraint.

| Parameter | Supplied value | Engineering meaning | Status |
|---|---|---|---|
| Cable family | FV / FV-D flat festoon cable | Basic-duty festoon systems with medium mechanical stress and movement on one plane. | User-supplied record |
| Typical applications | Indoor crane trolleys; main power supply for indoor cranes; process cranes; storage and retrieval systems. | Choose the flat cable as part of the complete festoon package. | User-supplied record |
| Travel speed | Up to 120 m/min | System speed limit must be checked against cable weight, trolley spacing, loop geometry and acceleration. | User-supplied record |
| Rated voltage — 0.5 mm² core | 300 V | Do not use the 450/750 V row for a 0.5 mm² core without a product-specific release. | User-supplied record |
| Rated voltage — 1 mm² core | U₀/U = 300/500 V | Applies to the stated 1 mm² category in the supplied record. | User-supplied record |
| Rated voltage — ≥ 1.5 mm² core | U₀/U = 450/750 V | Applies to the stated standard PVC category in the supplied record. | User-supplied record |
| LSOH rated voltage | U₀/U = 600/1000 V | LSOH section data are separately identified as 0.6/1 kV in the tables. | User-supplied record |
| Minimum bending radius | According to DIN EN 50565-1; shielded types and LSOH: 10 × Ø | Use the selected flat geometry and the original product instruction; no unshielded PVC value is inferred. | User-supplied record |
| Colour | Black | Confirm core identification and sheath marking on the released drawing. | User-supplied record |

| Temperature branch | Range / value | Use |
|---|---|---|
| H07VVH6-F / KYFLCY / KYFLTCY — flexing | −25°C to +60°C | Supplied temperature range for flexing service. |
| H07VVH6-F / KYFLCY / KYFLTCY — fixed | −35°C to +60°C | Supplied temperature range for fixed installation. |
| H05VVH6-F — flexing | −5°C to +60°C | Supplied temperature range for flexing service. |
| H05VVH6-F — fixed | −15°C to +60°C | Supplied temperature range for fixed installation. |
| LSOH — flexing | −25°C to +70°C | Supplied temperature range for flexing service. |
| LSOH — fixed | −40°C to +70°C | Supplied temperature range for fixed installation. |
| Maximum conductor operating temperature | 70°C; LSOH: 90°C | Use the selected compound and product-specific technical file. |
| Other temperatures | On request | Must be released for the ordered construction; no value is added here. |
Do not combine family values casually: H05VVH6-F, H07VVH6-F, screened PVC types and LSOH types do not share one universal voltage or temperature line. Select the cable by its exact type and part number, then use the matching electrical and thermal data.
3. Construction logic: why the cable stays flat under movement
Class-5 copper
The supplied construction record specifies stranded bare copper, class 5 according to VDE 0295. That is the correct starting point for repeated flexing, but conductor class alone does not define festoon life.

Parallel side-by-side arrangement
Cores or bundles are arranged in parallel. The bending plane, guide opening and trolley support must respect the flat orientation; forcing the cable to roll about its wide face changes the mechanical duty.

Shielded variants
KYFLCY and KYFLTCY use a copper braid or wrapped-wire shield with minimum 70% coverage in the supplied record. Shield continuity and EMC bonding must be included in the termination drawing.

LSOH option
FV-L uses a special insulation compound and polyolefin outer sheath, with 0.6/1 kV table data, halogen-free wording and smoke-density reference. It is a distinct construction branch, not merely a PVC colour change.

Source-format note: the supplied matrix contains the part-number line
4 X (4G1) and a screened-data geometry of 32.6 × 10.5 mm. They are reproduced without correction. Confirm the original manufacturer drawing before ordering, because a flat cable’s orientation and grouping notation affect the trolley hardware and termination.7. LSOH FV-L — separate low-smoke, halogen-free branch
LSOH FV-L is presented separately because the material system, voltage line and thermal/fire statements differ from the standard PVC branches. The first control row is reproduced exactly as it appears in the supplied text — 4 6 1.5 — because the source formatting is ambiguous. It should be confirmed as part of the original-datasheet check rather than silently rewritten.

8. How an engineer selects the correct FV / FV-D branch
| Decision gate | Choose / confirm | Why it changes the cable | Evidence to release |
|---|---|---|---|
| Application | Basic-duty festoon, single-plane movement | The family is not automatically suitable for uncontrolled torsion, outdoor heavy duty or continuous reeling. | Machine description, travel path and duty cycle |
| Voltage | 0.5 mm²: 300 V; 1 mm²: 300/500 V; ≥1.5 mm² standard: 450/750 V; LSOH: 600/1000 V | Voltage is tied to the exact type and cross-section category. | Part number, datasheet and system voltage |
| Core function | Power, control, data or mixed control/data | Core grouping and termination schedule change the product identity. | Schematic, terminal list and core coding |
| Shielding | Unshielded, KYFLCY, KYFLTCY or other specified shield | EMC, shield termination and minimum bending guidance change. | EMC plan, shield coverage and bonding drawing |
| Environment | Indoor / temperature / oil / dust / cleaning conditions | PVC and LSOH compounds have different temperature and fire evidence. | Ambient range, chemical list and cleaning method |
| Festoon mechanics | Speed up to 120 m/min; trolley spacing, loop depth, acceleration and end restraint | The cable table cannot by itself prove system life. | Festoon layout, trolley data and commissioning method |
| Geometry | Use listed d × B, not an assumed round diameter | Flat width and thickness govern guide clearance and bending orientation. | Selected part-number row and installation drawing |
| Fire / compliance | IEC 60332-1, KYFLCY Category C, LSOH smoke/halogen-free evidence as specified | A test method is not the same as a product certificate or project fire classification. | Product test report, declaration and market scope |
Power selection
Start with current and voltage, then choose H07VVH6-F or LSOH FV-L by the approved construction and thermal environment. Do not select only by cross-section.
Start with current and voltage, then choose H07VVH6-F or LSOH FV-L by the approved construction and thermal environment. Do not select only by cross-section.
Control selection
Lock the number of cores, core area, coding and permitted tensile load. A 24-core 1.5 mm² flat control cable is mechanically different from a 4-core power cable even when both use a class-5 conductor.

9. Festoon installation practice
Figure 5 — Load path through the festoon. Cable weight, permitted tensile load, trolley spacing and acceleration must be considered together.
| Observed issue | Typical mechanism | Engineering control |
|---|---|---|
| Cable edge abrasion | Guide roller, trolley clamp or beam edge contacts the flat edge. | Use suitable support width, rounded surfaces and correct cable orientation. |
| Loop crossover | Unequal trolley spacing, incorrect loop depth or a cable that is allowed to twist. | Set the festoon geometry at commissioning and maintain the same bend plane. |
| Tensile overload | Acceleration, emergency stopping or a heavy cable package transfers load to the end termination. | Use the supplied permitted tensile value as an input; design the complete support and end restraint. |
| Unexpected heating | High current, grouped flat cables, close loops or ambient temperature reduce heat dissipation. | Use ampacity according to DIN VDE and calculate the installed duty; no ampacity is invented here. |
| Shield discontinuity | Braid or wrapped wire is cut, poorly bonded or terminated inconsistently. | Provide a shield continuity and bonding test in the inspection plan. |
| Bending in the wrong axis | Flat cable is rotated through the wide face or forced around a guide designed for round cable. | Confirm d × B clearance and the manufacturer’s bending instruction. |
| Temperature mismatch | H05, H07 and LSOH ranges are mixed in one installation decision. | Put the exact cable type, ambient and conductor temperature on the approved drawing. |
Commissioning sequence: inspect the beam and trolleys; confirm the cable’s flat orientation; move slowly through the complete travel; check loops, edge contact, twist, shield movement and end restraint; measure electrical continuity; then increase speed and load in controlled steps.

A flat festoon cable is reliable when the electrical specification and the mechanical arrangement tell the same story. Most avoidable failures come from using the right conductor size with the wrong voltage branch, wrong shield treatment, wrong bending axis or unverified trolley geometry.
11. Feichun functional equivalent
Feichun Cable can engineer a functional equivalent for the confirmed FV / FV-D duty: flat power, control, screened control/data or LSOH festoon cable, built from an independent construction drawing and validated against the purchaser’s electrical and mechanical interface. The equivalent should match the required function and interface without copying third-party proprietary drawings, protected markings or undocumented construction details.
| Design gate | Feichun deliverable | Purchaser benefit |
|---|---|---|
| Electrical identity | Exact type, core schedule, voltage, conductor class, insulation and test voltage. | Prevents a visually similar cable from being used in the wrong voltage or control branch. |
| Flat geometry | Released d × B, lay, sheath construction and guide-clearance drawing. | Allows the trolley and festoon hardware to be checked before shipment. |
| Shield / EMC | Shield material, minimum coverage, bonding and continuity-test plan where required. | Reduces uncontrolled EMC and shield-termination risk. |
| Mechanical duty | Speed, loop geometry, trolley spacing, acceleration, tensile/support method and temperature. | Connects the cable data sheet to the actual machine. |
| Fire / environment | PVC or LSOH material evidence, oil/chemical statement, fire and smoke reports. | Creates a traceable export technical dossier. |
| Production traceability | Conductor resistance, dimensions, marking, routine tests and batch records. | Supports inspection, commissioning and future replacement. |
Certification capability: for export projects, Feichun can coordinate product-specific documentation around ATEX, IECEx, VDE, CE, UKCA, EAC and the Russian Fire Safety Certificate when the ordered construction and application require those routes. The exact certificate scope, marking and validity must be confirmed for the product, market and installation; no certification is implied merely by the FV / FV-D family name.
12. RFQ checklist for FV / FV-D
| RFQ field | Minimum answer required | Why it matters |

Experienced-engineer reading: FV / FV-D is a well-balanced flat-cable concept for basic indoor festoon systems where space, cost and predictable single-plane movement matter. Its strength is the controlled combination of flat geometry, class-5 copper, power/control/data branches, screened options and an LSOH alternative. Its limit is equally clear: the cable must stay within the released plane, temperature, voltage, speed, bending, tensile and environmental envelope. Choose the exact table row first; then design the festoon around that row.
