Festoon Fiber Optic Cable

Our festoon fiber optic cable hangs like a curtain and travels continuously with the equipment, making it the ideal transmission solution for festoon systems on cranes, long-travel material handling lines, and any lateral‑motion machinery. It is engineered for demanding applications in heavy industry, port terminals, coal yards, and other severe operating environments.

Product Structure

1. Optical fiber

2. Inner sheath – High‑strength composite material

3. Anti‑torsion layer – Steel wire armor

4. Outer sheath – Premium PUR imported from the USA

Technical Parameters

Bending radius

• Fixed installation: 5 × cable outer diameter

• Mobile installation: 6–10 × cable outer diameter

Temperature range

• Fixed installation: -40°C to +80°C

• Mobile installation: -30°C to +70°C

Key Features and Benefits

• Superior torsional resistance – The steel wire armor layer effectively prevents twisting and kinking during high‑cycle festoon operation.

• Exceptional mechanical durability – The American‑imported PUR jacket delivers outstanding flexibility, abrasion resistance, tensile strength, and cut resistance.

• Harsh‑environment reliability – Resistant to oil, acids, alkalis, hydrolysis, UV radiation, and weathering; optionally available with flame‑retardant properties.

• Wide operating temperature – Performs reliably from -40°C up to +80°C in fixed installations.

• Tight bending capability – Small minimum bend radius (6×OD mobile) suits compact festoon loops and high‑flex applications.

Typical Applications

• Overhead cranes and gantry cranes

• Coal yard car dumpers and stacker‑reclaimers

• Metallurgical cranes and ladle cranes

• Long‑travel material handling festoon systems

• Port and dock heavy‑lift equipment

• Any side‑traversing or trolley‑mounted machinery in heavy industry

Frequently Asked Questions

In what environments can this festoon fiber optic cable be used?
The cable is purpose‑built for outdoor and indoor heavy‑duty environments, including steel mills, ports, coal terminals, and chemical plants. The PUR sheath offers excellent resistance to oil, chemicals, UV, and extreme weather.

Does the steel wire armor provide enough torsional protection for high‑cycle festoon moves?
Yes. The dedicated anti‑torsion steel wire layer significantly increases torsional stiffness and prevents the “corkscrew” effect, ensuring stable signal transmission even under continuous reversing bends and twists.

Is a flame‑retardant version available?
Yes. A flame‑retardant PUR jacket is available as an option. Please specify your flame‑retardance requirements (e.g., IEC 60332‑1‑2) when you inquire.

What is the minimum bending radius during operation?
For mobile festoon installation, the minimum bending radius is 6 to 10 times the cable’s outer diameter, depending on the specific layout and cycle frequency. Fixed installation allows a tighter bend down to 5 × OD.

Can the cable withstand frequent acceleration and deceleration on fast‑moving trolleys?
Absolutely. The combination of a robust composite inner sheath and the PUR outer jacket gives the cable high tensile strength and dynamic flex life, making it suitable for high‑speed trolleys and rapid direction changes.
