3) Name of the manufacturer
4) Year of manufacture
5) Length marking
6.2 Cable Re-marking
The re-marking shall be indent-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 2000 m. 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.
6.4 Cable Reel
6.4.1 Details given below shall be distinctly marked on a weather proof materials on
both outer sides of the reel flange:
(1) KRONE
(2) Length of cable in meters
(3) Cable type and fiber counts
(4) Gross weight in kilograms
(5) Reel number
(6) Year of manufacture
(7) Arrow showing the direction the drum shall be rolled
6.4.2 The cable shall be wound on the reel designed to prevent damages during
shipment and installation.
6.4.3 The arbor holes provided in the reels shall be at least 65 mm and at most 120
mm in diameter. The arbor hole on each flange shall be reinforced with a bearing
plate.
