PACKING AND DRUM
Our cables are coiled on 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 Drum
(The barrel core is a metal structure)
Note: The drum size & cable weight as above is estimated and final size & weight shall be confirmed before shipment.
The inner end and the outer end of cable are equipped with heat shrinkable end cap and the drum protected with strong wooden batten.
