Medium Voltage Reeling Cable for Power, Control and Fibre Optic Transmission
The TEBAOFLEX medium voltage reeling cable is engineered for heavy mobile equipment where energy supply, control circuits and fibre optic communication must operate together in one flexible cable system. This 8.7/15 kV cable is suitable for dynamic reeling applications exposed to tensile load, torsion, repeated bending and outdoor operating conditions.
With integrated 24FO 9/125 fibre optics, control cores and flexible tinned copper power conductors, this cable is designed for container cranes, large material handling equipment, open-cast mining machines, excavators, dumpers and mobile crushers.
Key Features
- Integrated power and data transmission: Combines 8.7/15 kV power cores, control conductors and 24 fibre optic cores in one cable construction.
- Designed for reeling operation: Suitable for mono-spiral reels, cylindrical reels and mobile equipment requiring repeated winding and unwinding.
- High mechanical resistance: Reinforced with Kevlar aramid fibre mesh and torsion protection for tensile load, twisting and dynamic movement.
- Flexible tinned copper conductors: Class 5 tinned copper conductors support flexibility and improved oxidation resistance.
- Heavy-duty rubber sheath: 5GM5 rubber outer sheath provides resistance to abrasion, oil, moisture, UV, ozone and outdoor weather.
- Flame retardant performance: Designed according to IEC/EN 60332-1-2 flame-retardant requirements.

FAQ
What is a medium voltage reeling cable used for?
A medium voltage reeling cable is used to supply power to mobile equipment through cable reels. It is commonly used on cranes, excavators, open-cast mining machines and large material handling equipment.
What does integrated 24FO mean?
Integrated 24FO means the cable includes 24 fibre optic cores inside the cable construction. This allows the same cable to carry both medium voltage power and fibre optic data signals.
Is this cable suitable for container cranes?
Yes. This cable is suitable for container cranes and port handling equipment where reeling movement, tensile load, torsion and data communication are required.
Can this cable be used outdoors?
Yes. The heavy-duty rubber sheath is designed for outdoor use and offers resistance to moisture, UV, ozone, oil and weather exposure.
What bending radius should be used?
As a general guide, the minimum bending radius is 6 x D for fixed installation, 12 x D for reeling operation and 15 x D when used with sheaves. Final values should be confirmed according to the equipment design.
Can TEBAOFLEX customize the fibre optic configuration?
Yes. Fibre optic designs such as G50/125, G62.5/125 and E9/125 can be discussed according to project requirements. Other control core and sheath options may also be available.
What information is needed for a quotation?
Please provide the voltage rating, conductor size, number of control cores, fibre optic requirement, reel type, travel speed, bending radius, tensile load, installation environment and required cable length.
