6.2 Cable Re-marking
The re-marking shall be marked, preferably with yellow characters, on the outer cable
sheath. Any cable that contains two sets of cable markings shall be marked to indicate the
color of the marking to be used.
6.3 Cable Packing
6.3.1 Standard length of cable shall be 4km. Other cable length is also available if requested
by customer.
6.3.2 Each length of the cable shall be wound on a separate wooden reel.
6.3.3 Both ends of the cable shall be sealed with suitable plastic caps to prevent the entry of
moisture during shipping, handling and storage.
6.3.4 The cable ends shall be securely fastened to the reel to prevent the cable from becoming
loose in transit or during placing operations.
6.3.5 The inner end of the cable is housed into a slot on the side of the reel without extra cable
length for testing.
6.3.6 Circumference battens or wood-fiber board shall be secured with steel bands to protect
the cable during normal handling and shipping.
