Cable Handling & Laying

Storage :

  1. Cable drums should be stored on dry hard solid (preferably on concrete surface).

  2. Sufficient space should be in between the drums for air circulation.

  3. The drums should stand on the wooden battens if supplied on wooden drums. The drums must be not kept with flanges horizontal position i.e. in flat position.

  4. Cables should be protected from direct sun rays. To ensure this the cover of the drums must not be removed.

  5. Though overhead cover of storing place is not always required, it is recommended that the drums must be protected from heavy rainfall during monsoon.

Minimum Bending Radii = 20 Times diameter of cable.

D is the overall diameter of the cable

Side Wall Pressure

The permissible side wall pressure is 5000N/m (500 kg/m) during installation

SWP=F/R
Where SWP = Side wall pressure in NIm (or kglm)
F = Pulling force in N (or kgf)
R = Bending radius in m


Maximum pulling force :
Pulling Force should normally not to exceed:

Copper conductors : 50N/mm2 (5kg/mm2)
Aluminium conductor : 30N/mm2 (3kg/mm2)

Rolling Cable Drums : Rolling of drum on the ground should be avoided as much as possible as this might cause damage of the cable. In case, it is absolutely necessary the drum should roll in the direction of the arrow marked on the drum.

Water sealing : The cable ends are sealed during transport, storage and installation to avoid ingress of water into the cable conductors.

The cable end must never be left unsealed in a trench. The end sealing should be checked after pulling out the cable from the drum.
