ÖLFLEX® TORSION D FRNC
Screened, cold and oil-resistant cables for flexible applications under torsional load, halogen-free – 0.6/1 kV
The special design reliably compensates for the permanent torsional drip loop movements inside the wind turbine between the nacelle and the tower; The high flexibility and good dismantling
and stripping properties enable easy space-
saving cable installation and fast processing; Sea water-resistant for onshore and offshore
applications; FRNC = Flame Retardant Non Corrosive
– Reduction of flame-propagation and
density and toxicity of smoke gases
in the event of fire
– Minimisation of damage to buildings
and production facilities
– Safety for staff and in
areas with high density of people; The copper wrapping of the screened D
version protects against electromagnetic
interference
- Torsion resistant, Cold flexible and Oil resistant for drip loops
- Halogen-free, Highly flame retardant, Low smoke density
- EMC/Screened

Application range
- For fixed and flexible installations, as well as for applications with torsional movements (e.g. machinery, wind turbines)
- Very suitable for installation in the drip loop, between the rotating nacelle and the stationary windmill tower, to connect the generator to the control units
Benefits
- The special design reliably compensates for the permanent torsional drip loop movements inside the wind turbine between the nacelle and the tower
- The high flexibility and good dismantling
and stripping properties enable easy space-
saving cable installation and fast processing - Sea water-resistant for onshore and offshore
applications - FRNC = Flame Retardant Non Corrosive
– Reduction of flame-propagation and
density and toxicity of smoke gases
in the event of fire
– Minimisation of damage to buildings
and production facilities
– Safety for staff and in
areas with high density of people - The copper wrapping of the screened D
version protects against electromagnetic
interference
Product Make-up
- Extra-fine wire conductor made of bare copper
- Core insulation: polyolefin compound
- Core connection optimised for high torsion requirements, twisted in layers
- Optional screening (D): wrapped with braided tinned-copper wires
- Outer sheath: special compound, halogen-free, black (RAL 9005)
Norm references / Approvals
- Use of leading, European metric stranded conductors according to the IEC scale for conductor nominal cross-sections in mm² according to IEC 60228/VDE 0295, braided conductor class 6 (tinned): For converting to AWG, odd-numbered nominal AWG cross-sections must be excluded. The next lowest nominal AWG conductor cross-section in mm² must then be allocated to the metric nominal conductor cross-section in mm² (according to IEC 60228) (please refer to the technical catalogue appendix T16). This is to ensure that the normative current rating defined by the nominal AWG conductor cross-section does not exceed the physical/real current rating defined by the nominal IEC conductor cross-section that is actually used
- Cable type certifications: UL AWM style 21288 by UL acc. UL standard as well as cUL AWM II A/B by UL acc. CSA AWM standard
