Only qualified people de-energise
Isolation, lockout, proving dead and grounding are work for qualified electrical personnel under the site's safety programme. A buying desk cannot and should not authorise anyone to open a termination or test a cable.
Charge stored in the cable
Shielded cable behaves like a capacitor. After isolation it can retain a charge, which is why the discharge and grounding step exists in the switching procedure. Cable that has been cut without discharging is a hazard, not a bargain.
Sealed ends and moisture
Cut ends should be sealed as soon as the cable is cut. Moisture ingress into XLPE insulation is not visible and it destroys the dielectric properties that make the cable reusable, so an unsealed end changes the review from reuse toward recovery.
What to send before a move
Send the voltage class, the construction, the reel tag, the footage, and a statement that the cable is de-energised and released. Photograph both ends and the seal. Nothing should be moved, cut or coiled until that release exists in writing.
