Packing Information
Our packing standards follow the highest regard for sustainability
01 cable length
Available in standard 500m and 1000m drum lengths to suit diverse project needs
02 Drum length
Higher drum lengths can be provided in order to reduce the number of joints for a cable route.
03 drum material
Supplied in recyclable steel drums — stronger, safer, and eco-friendly, making them a sustainable choice over wooden drums.
04 drum covering
The cables on the steel drums shall be covered with superior quality Poly-Propylene (PP) sheath to avoid external exposure.
05 enhanced cable protection
Covered with high-quality PP sheath for enhanced resistance against external damage
06 water prevention
Heat Shrinkable end caps shall be provided on both ends of cable to prevent water ingress into the cable.
