4) Length marking

6.2 Cable Packing
6.2.1 Standard length of cable shall be 2km and 4km. Other cable length is also available if
required by customer.
6.2.2 Each length of the cable shall be wound on a separate wooden reel.
6.2.3 Both ends of the cable shall be sealed with a suitable plastic cap to prevent the entry of
moisture during shipping, handling and storage.
6.2.4 Wood-fiber board or circumference battens shall be laid on cable between flanges and
fixed by steel bands.
6.2.5 The cable ends shall be securely fastened to the reel to prevent the cable from becoming
loose in transit or during placing operations.
6.3 Cable Reel
6.3.1 Details given below shall be distinctly marked on a weather proof materials on both
outer sides of the reel flange:
