PILC and HPFF: the cable that needs a plan first.

PILC is paper-insulated, lead-covered cable. Impregnated paper is wound around the conductor, a lead sheath is extruded over it, and an outer serving protects the lead. The paper is the insulation and the lead is the moisture barrier, and the cable depends on both. Neither tolerates a careless move.

Once the sheath is breached, paper takes moisture quickly and does not give it up. That is why ends are sealed, why a cut is a decision rather than an accident, and why buyers look at the sheath before they look at the conductor. The sequence of inspection rarely changes.

HPFF puts three paper-insulated cables inside a steel pipe filled with dielectric oil under pressure. A pumping plant and pressurising equipment hold that pressure, and stop joints divide long runs into sections. The pipe, the oil and the cables are one system, and no part of it is moved alone.

Removing a section means depressurising, draining and containing the oil before anything is opened. Oil is sampled and characterised, and the result decides how it is handled. That sequence is the owner's procedure, and it is not shortened for a pickup or rearranged around a truck.

Lead-sheathed cable is heavy and it does not like to bend. The sheath deforms under its own weight across a span, and a bend tighter than the cable's rating creases it permanently. Drums, racks and cradles exist for a reason, and a forklift is not one of them.

A drum that has stood on soft ground for years may hold a sound cable and a rotten drum. The drum is part of the handling plan, not a detail, because a reel that cannot be lifted cannot be loaded and a cable wound onto a poor drum can be crushed in transit.

• Drum size, and whether the original drum is sound enough to travel.
• Weight per length and total weight, for crane and trailer selection.
• Bend radius and support spacing needed while the cable is wound.
• Whether the run is drained, sealed and capped, or still holding oil.

A handling plan names the cut points, the isolation and release documents, the oil containment method, the winding or drumming arrangement, the lifting equipment and the route out. It is written before a saw is picked up, and both sides sign it before the first drum is moved.

Where a utility still operates the construction, the plan is written with its engineers rather than around them. Cable removed under their procedure and documented as such is a different lot from cable cut out by a demolition crew on a schedule, and the review reflects that difference in every line.

No cut, no coil, no load until isolation is proved in writing, the oil question is answered and the handling plan is agreed.
