DØ: outer cable diameter     DØ*: ~ with Elastic Inlays

Application with Elastic InlayElastic Inlay

  • as padding of the cables (for diameters ≥ 60 mm) to avoid damage of the cables under strain and/or change of surrounding temperature
  • as secure fixation of the cables and absorption of forces due to the weight of the cables at vertical sections in any height (wind turbine generators, masts, shafts)

 

Additionally, the Distance Wedge is needed cables with impregnated paper insulation for high- and extra high-voltage. For the range of outer cable diameter check Distance Wedge data sheet.
