5. Packing and Drum 5.1 ZTT cables are packed in carton, coiled on Bakelite & wooden drum. During transportation, right tools should be used to avoid damaging the package and to handle with ease. Cables should be protected from moisture; kept away from high temperature and fire sparks; protected from over bending and crushing; protected from mechanical stress and damage. Wooden strip seal Wooden flange Cable fixing point Inner tub Axle hole Cable trough 5.2 The color of cable marking is white. (The printing shall be carried out at interval of 1 meter on the outer sheath of cable) The inner end of cable is then sealed with heat shrinkable end cap to prevent ingress of water and is made available for testing. The outer end of cable is equipped with heat shrinkable end cap. Outer sheath marking legend can be changed according to user s requests. 5.3 Outdoor cable packing Bakelite & wooden drum Strong wooden batten protection www.zttcable.com ALL Rights Reserved Copyright 2014 page 11 of 11
