Packing and Drum
The cables are packed in carton, coiled on Bakelite & Fumigated 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.
Packing length :2000-5000m/reel.
