(N)SHTÖU Cable for Reeling Drums and Festoon Systems
(N)SHTÖU cable is a 0.6/1 kV low-voltage rubber cable engineered for equipment where the power cable is repeatedly reeled, paid out, bent or guided while the machine is operating. Its flexible Class 5 conductor, elastomeric insulation and reinforced sheath system make it suitable for winding drums, horizontal reeling installations, festoon systems, hoists, lifting devices and transport machinery operating under heavy mechanical load.
Unlike a general-purpose flexible power cable, this design includes an anti-torsion textile braid embedded within the sheath system. The braid helps the cable resist twisting and controls deformation when the moving equipment changes direction or the cable is wound in layers. This is especially relevant where cable life depends on correct drum geometry, controlled pulling force and a bending radius matched to the installation.

Applications
- Motorized and spring-operated reeling drums
- Horizontal reeling systems on cranes and transport machinery
- Festoon systems with controlled cable loops
- Hoists, lifting equipment and material-handling machinery
- Drum and drag-cable service in dry, damp and wet industrial areas
- Mobile power connections exposed to bending, tensile and torsional stresses
Selection Notes for Buyers
Select the conductor cross-section from the required current, route length, voltage-drop limit, ambient temperature, grouping and the applicable DIN VDE 0298-4 current rating. Reeling installations need an additional thermal check because multiple energized cable layers on a drum cannot dissipate heat as effectively as a freely exposed cable.
Mechanical selection should include the minimum drum and guide-roller diameters, the bending radius required by DIN VDE 0298-3, acceleration, travel distance, reversing frequency and maximum pulling force. The travel-speed figures are upper limits for the stated installation modes, not a substitute for checking the complete cable-management system. Keep the working tensile load within 20 N/mm² and do not use the cable as a load-bearing lifting member.
For an RFQ, provide the conductor arrangement, required length, drum orientation, number of cable layers, travel speed, duty cycle, ambient temperature, oil or water exposure, sheath colour and required inspection documents. This information allows the cable dimensions, conductor size and mechanical design to be checked against the actual machine.
FAQ
What is (N)SHTÖU cable used for?
(N)SHTÖU cable is used to supply power to reeling drums, festoon systems, hoists, cranes, lifting devices and mobile transport machinery exposed to repeated bending, pulling and torsional movement.
What is the voltage rating of (N)SHTÖU cable?
The rated voltage is 0.6/1 kV, with a stated AC test voltage of 3.5 kV.
Can the cable be used on both reels and festoon systems?
Yes. The supplied data states travel speeds up to 120 m/min for horizontal reeling and up to 240 m/min for festoon systems, subject to the mechanical layout and operating conditions.
Why does the cable include an anti-torsion textile braid?
The embedded textile braid helps distribute torsional forces and limits distortion as the cable bends, reverses direction or winds onto a drum.
How should the conductor size be selected?
Check load current, route length, voltage drop, ambient temperature, grouping and heat dissipation on the reel. Current-carrying capacity should be determined according to DIN VDE 0298-4 for the actual installation.
Is (N)SHTÖU cable suitable for wet industrial areas?
It is intended for dry, damp and wet industrial rooms. Continuous immersion or other special water exposure should be confirmed separately before ordering.
