HANDLING AND INSTALLATION OF CABLE
1.Minimum bending radius and permissable pulling tension - to prevent damage on electrical and physical properties of the cable
Lifting by crane Drum rolling direction Do not lay on flanges
Lifting drum by forklift correctly
Drums secure adequately during transportation
HANDLING AND INSTALLATION OF CABLE
DO NOT attempt “coiling” on the ground
On the ground cable can be FLAKED in a figure of eight formation
