PILC & HPFF cable · Harris County / Greater Houston
We buy PILC and HPFF cable.
Paper-insulated lead-covered cable and high-pressure fluid-filled pipe are still in service under older Houston plants. When a section comes out, the oil and the lead decide how it is handled.
PILC is the older construction: a copper conductor, paper insulation, a lead sheath, and often a tape armour over the serving. HPFF takes a different route, carrying paper-insulated cable inside a steel pipe filled with dielectric fluid held under pressure. Both were standard for utility and industrial distribution before extruded insulation took over, and both are still in service in older Houston systems. The cable is old, but it is not rare.
Neither is a scrap lot in the ordinary sense. The lead sheath, the impregnating oil and, in HPFF, the fluid inside the pipe all change how a section is cut, drained, moved and documented. A buyer needs to know what is inside the cable before agreeing to take it. A seller who can answer that question plainly saves a week of back and forth, and a seller who cannot still gets an honest review.
Telling PILC from extruded cable on sight
The sheath is the giveaway. A PILC end finishes in a dull grey lead tube that dents under a thumbnail, with a wiped solder joint where two lengths were joined. Extruded cable ends in a polymer jacket over a semi-conductive layer, and the jacket print names the insulation. Cut a PILC end and you find oil-impregnated paper wound in tight laps around the strands rather than a solid wall of cross-linked polyethylene.
HPFF is easier to spot. It arrives as steel pipe, often with a cathodic protection test station, pressure gauges, valves or a fluid reservoir at one end. If cable sits inside a pipe that was kept charged, the construction is fluid-filled, and the pipe itself is part of the lot whether or not anyone wants to keep it. Potheads and joints usually travel with the section.
- Lead sheath with wiped joints and a dull grey cut end
- Tape armour or a serving under an outer covering
- Steel pipe with gauges, valves or a fluid reservoir
- Paper laps around the strands instead of an extruded wall
- Duct banks and older manholes rather than cable tray
Keep the cut ends wrapped. Paper that has dried out and drawn water behaves differently from paper that stayed sealed, and the change shows within days in Houston humidity.
Why a fluid-filled section is a specialist lot
Anything holding oil under pressure has to be isolated and drained before it travels. That is the owner's procedure, not the buyer's, and it normally involves a fluid sample, a defined drain point and a record of how much fluid came out. A section that is still charged is not a collection job. It is a hazard with a cable inside it, and it stays where it is until the owner is ready.
Lead adds the second constraint. The sheath is a regulated material at the handling and disposal end, and anyone who takes PILC takes that obligation with it. This does not make the cable untouchable. It makes it a lot that has to be planned rather than picked up, with the pieces contained, the ends sealed and the paperwork kept with the material.
Ask the owner for the drain record and the fluid volume before the section is cut. Without those two numbers the lot is speculative.
What a decommissioned section is worth reviewing
Retired duct runs, substation feeders and plant mains are usually cut into handling lengths rather than left on a reel. At that point length matters less than condition and metal content. The copper sets the floor, and the lead sheath and steel armour add weight that has to be counted honestly rather than guessed at from a photograph of a pile.
Drained, dry, capped sections with a known voltage class and some record of where they came from get reviewed seriously. A mixed pile of cut PILC with no indication of voltage or oil history is still bought, but it is read as metal recovery rather than as cable anyone could re-install in a duct. Both outcomes are reasonable. They are not the same lot.
- Voltage class, from the tags, the drawings or the cable print
- Conductor size and whether it is copper
- Whether the section is drained and the ends capped
- Approximate length, or the number of cut pieces
- Whether pipe, armour and potheads are included
A photograph of the cut end and one of any surviving tag settles more questions than a paragraph of description.
Sending a PILC or HPFF lot from the Houston area
Start with a location and an owner. Older PILC turns up in utility duct banks, refinery substations, channel-side facilities and a few pre-war industrial buildings around the city. Each has its own access rules, and a plant gate is not a contractor yard with a forklift on standby. Tell us which of those you are standing in and who controls the material.
Send what is known: voltage class, approximate length, whether the section is drained, and whether potheads, armour and the pipe are part of the sale. If the owner is a utility or a plant, their surplus process runs first, and the handling plan is agreed before anyone books a trailer. That sequence does not change because the cable is old.
One detail worth stating plainly is whether the cable is still connected. Old PILC in a duct bank is often cut and left in place rather than pulled, and a section still terminated at both ends is a different job from one already lying on the ground. Say which it is, and who is responsible for the cut.
Questions sellers ask
How do I tell PILC from XLPE cable?
Look at the cut end. PILC shows a lead sheath that dents under a thumbnail and oil-impregnated paper wound around the strands. XLPE shows a solid extruded wall under a polymer jacket, and the jacket print names the insulation. A wiped solder joint or a pothead confirms the older construction.
Do you buy HPFF cable that is still charged?
No. A charged section has to be isolated, sampled and drained by the owner before it can move, and that work follows the facility's own procedure. Once it is drained and the fluid volume is recorded, the pipe and the cable inside it can be reviewed like any other decommissioned lot.
Is the lead sheath a problem for a seller?
It is a handling consideration rather than a barrier. Lead is regulated at the disposal and recycling end, and any buyer who takes PILC takes that on. For the seller the practical questions are whether the section is drained, how it has been cut, and whether the pieces load safely.
What length of PILC is worth collecting?
Cut pieces rather than reels are the norm, so length is measured in pieces and weight more than in footage. One short piece usually joins a larger load. A whole duct run or feeder pulled in handling lengths is a lot on its own.

Have this cable on the yard?
Tell us what is on the reel, where it sits and what condition it is in. A buyer reviews the lot, asks for photographs of the tag and the cut end, and comes back with a real answer — not a request to call a call centre.
- Cable type, size and voltage class
- Footage, reel count or weight, and condition
- City, and whether the site has loading equipment
