moisture during shipping, handling and storage.
6.3.4 The cable ends shall be securely fastened to the reel to prevent the cable form becoming loose
in transit or during placing operations.
6.3.5 Circumference battens or Wood-fiber board shall be secured with bands to protect the cable
during normal handling and shipping.
6.4 Cable Reel
6.4.1 Details given below shall be distinctly marked with a weather proof material on the both outer
sides of the reel flange. Other shipping mark is also available if requested by customer.
1) Purchaser’s name
2) Cable type and fiber counts
3) Length of cable in meter
4) Gross weight in kilogram
5) Reel number
6) Name of the manufacturer
7) Year of manufacture
8) Arrow showing the direction the drum shall be rolled
6.4.2 The cable shall be shipped on reels designed to prevent damage to the cable during shipment
and installation.
