Calculated span length is 50 m. This permissible span length is only reference. For more detailed information, see the table of load conditions in this specification. 

Construction 

  • Material: The individual ducts are made of HDPE.
  • Colour coding: The ducts are colour-coded according to customer specifications, FIN 2012, ANSI/TIA, IEC or other.
  • Strength member: Glass fibre reinforced plastic (FRP) rod.
  • Trace wire: Duct bundles can be equipped with a tracer wire according to customer specifications.
  • Outer sheath: The outer sheath consists of UV resistant black polyethylene compound (PE). The nominal sheath thickness is 1,0 mm. Sheath marking is printed on one meter intervals.
