Depending on site requirements, the downconductor(s) may have their upper terminations completed at a pre-specified end of the cable by nVent ERICO before shipment. These terminations will be protected by a short length of flexible PVC tube. It is VERY IMPORTANT that when removing these tubes, they are not removed with a knife or cut in any way as this will damage the outer layer of the termination. - Page 14 Downconductor un-terminated end lowered to the ground Downconductor preterminated end on the outside of drum Figure 6: Cable pre-termination and drum locations INCORRECT CORRECT Figure 7: Incorrect and correct cable hoisting methods 14 | nVent.com/ERICO...
