Legal compliance

  • Directive 2015/863/EU (RoHS)
  • Regulation (EC) No. 1907/2006 (REACH regulation)

Constructional features

  • Particularly high dynamic and mechanical strength and heat resistance due to special fibreglass-reinforced polyamide
  • Safe restraint of dynamic forces of high short circuit currents, without damage to the cables, also for multiple short circuits
  • Following the tests to IEC 61914 – cable cleats for electrical installations - reports from accredited institutes regarding dynamic short circuit currents, the fire-resistance of the material, and mechanical properties of the Cable Clamps are available
  • Very low surface pressure on cables due to Cable Clamps’ large contact area
  • Unrestricted application both indoor and outdoor in extreme climates such as deserts, tropics, high altitudes, arctic climate, coastal salt fogs, flooding and ozone due to special resistance to ageing, ultraviolet rays and ozone
  • Easy to mount without special instruments and maintenance-free
  • Fastening of Cable Clamps adaptable to all local conditions

Following the tests to IEC 61914 on Series K Cable Clamps approved results in highest classification

Use of Elastic Inlays:

  • As a cushion for elastic adjustment of cable diameter changes due to operational load changes and/or changes in the ambient temperature
  • Precise cable fixation and absorption of weight forces, primarily on cables installed along inclines or attached to vertical surfaces where restraint of axial movement is essential
  • Compensation of vibrations, e.g. in wind turbines, without reducing retention forces
  • Expansion of the Clamp’s clamping area, for cables with a smaller outer diameter
