5. Packing and Drum
55..11 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 andcrushing; protected from mechanical stress and damage.
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 mar king legend can be changed according to user’s requests.
