Maximum Capacity of PVC


  Minimum bending radius
 
 
None of the cables specified in to standards should be bent during installation to a radius 
smaller than that given below. So wherever possible, larger installation radii should be used.

Drum handing

Handle the drums with care! It is always recommended and a must with heavy drums - to lift drums with a fork-lift truck or a crane when removing them from the vehicle. Always take care to lower t drums into an upright position on their flanges.
 

Internationally practiced LSZH cables installation methods :

  1. Avoid the cables, while installing from extra friction. Try to lay the cables with good workmanship methods. void the cables from rough edged surface, sharp corners so to stay within minimum bending radius.

  2. For better assistance, you can use a little lubrication on the cable surface.

  3. Avoid pulling / unwinding cables, while laying, with heavy machining.
