The (N)TSKCGEWOEU medium-voltage fibre optic reeling cable combines power conductors, split earth conductors and integrated optical fibres in one flexible, reinforced construction. It is designed for mobile equipment operating under high mechanical stress, including fast-moving container cranes and large moving machinery.
Integrated power and data transmission
This 8.7/15 kV reeling cable combines energy transmission with optical data transmission in a symmetrical three-core design. The construction includes tinned fine-stranded copper conductors, EPR insulation, semiconductive field-control layers, a Kevlar braided reinforcement layer and a red double-layer PCP sheath system.
- For demanding motion: suited to high travel speeds, dynamic tensile loads, repeated changes of direction, roller travel and torsional stress.
- Integrated fibre optics: the documented configuration contains 18 E9/125 optical fibres; alternative fibre counts and types can be specified where required.
- Reinforced sheath system: EPR inner sheath, polyester anti-torsion braid and abrasion-resistant PCP outer sheath.
- Outdoor resistance: documented for unrestricted indoor and outdoor use with resistance to ozone, UV exposure and moisture.

Selection and installation guidance
Fibre-optic termination requires suitable tools and trained personnel. Provide the reel, connection and travel details so TEBAOFLEX can review the required fibre design, bending radius and tensile conditions before quotation.
