Cable Design

These PVC+RUBBER – insulated flat flexible cables are used for installation as power and control cables tracks and carries, transport system, tool machinery, in particular for hoisting equipment, crane and container bridges and in all circumstances in which the cable is subjected to severe bending and contionous movement in are not suitbale for outdoor applications or ambient air temperatures below 0c or above+40cc.

Characteristic Feature

  • The reduced dimension means that these flat flexible cables are space-saving compared to around flexibe cables.
  • The cables must be rolled up and suspenden such that no twisting or kinks accur.
  • The cables should be freely suspended, secured at one end,in the lift shaft for several days before being instlled.
  • These should be no sharp edges in the lift shaft behind the moved cables such as support between front and rear side of multiple-lift shafts which could damage the cables.
  • Chemical resistance properties of PVC-refer also to the Tbale of Technical Guidelines.
