PRESERVATION/STORING & HANDLING OF CABLE DRUMS

1. STORAGE a. The site chosen for storage of cable drums should be well-drained and should preferably have a concrete surface, which will not cause the drums to sink and so lead to flange rot and cause extreme difficulty in moving the drums. b. The drums should be stored in such a manner as to leave sufficient space between them for air circulation. It is desirable for the drums to stand on battens placed directly under the flanges. c. In no case shall the drums be stored “on the flat side” i.e. with flanges horizontal. d. For drums, overhead shade is not essential except in areas where the rainfall is heavy. e. The cables should however be protected from direct rays of Sun by leaving the battens on or by providing some form of sun shielding. f. Cable ends must be sealed against water ingress at all times. 2 HANDLING a. The drums should be rolled only in the direction of the arrow, indicated on them. b. No cable drums shall be slung except by a bar through the center bore. Also the cable drums shall be stored away from Boilers or Furnaces. c. When unloading the drums from truck, a crane or forklift should be used if available and the drums carefully lifted and deposited on the ground. If crane is not available then the drums should be carefully rolled down a suitably arranged ramp or rail. Under no circumstances should the drums be dropped to the ground, as the shock may cause serious damage to the inner layers of the cables. d. Transportation over long distance, from storage site to work spots – The drums should be mounted on cable drum wheels strong enough to carry the weight of the drums, which are pulled by means of rope, or alternatively they may be mounted on trailer or vehicle with low loading platform for transportation to the destination.

INSTALLATION

OCI cables are suitable for installation in the ground, duct or air as recommended by all standards and specifications. OCI cables are easier to handle and install.

Wherever possible, installation radius should be large than those given below:
