5. PACKING AND DRUM
 
6.1 Our cables are packed in carton, coiled on Bakelite & wooden reel. During transportation, right tool should be used to avoid damaging the package, and handle carefully. Cables should be protected from moisture; Cables should be kept away from high temperature condition and spark; Cables should be protected from over bending and crushing; Cables should be protected from mechanical damage.
 
 
 
 
 
 
 
6.2 The color of marking is white.( At every meter, the outer sheath of the fiber cable shall be printed )
The inner end of cable is 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 making legend can be changed according to user's requests.
