Prysmian Acquires Encore Wire: 7 Cable Questions, Answered

These are the questions I keep hearing from contractors, purchasing managers, and design engineers when the subject of Prysmian comes up. I'm a quality and compliance manager for a telecom infrastructure contractor. I review cable deliveries before they get booked into inventory—roughly 400 line items a year. In 2024, I rejected about 6% of first deliveries for spec mismatches, damaged jackets, or paperwork that didn't line up. So this isn't a marketing overview. It's what I pay attention to when Prysmian products land on the receiving dock.

This was accurate as of early 2025. The Prysmian catalog and corporate structure are moving quickly after the Encore Wire deal, so verify current part numbers, legal entities, and lead times with your distributor.

What does Prysmian actually make?

Prysmian is a wire and cable manufacturer. Power cables, fiber optic cables, communication cables, fire alarm cable, cable accessories, cable cleats, enclosures—if it carries electricity or light, they probably make a version of it.

What matters to me is that 'Prysmian' is not a single product. A 15kV power cable and a fire alarm cable are different engineering worlds. The brand tells you about the spec system and the quality expectations. It doesn't mean every product rolls off the same line. When I'm approving a delivery, I look at the specific product family, the standards listed on the drum tag, and the test report. That habit has caught more than a few mismatches. It's tempting to think that a cable is a cable. But the spec sheet is the real product.

Where is Prysmian cable made?

Short answer: it depends on the product. Prysmian manufacturing is spread across the globe. In North America, the locations I see most on certificates of origin are Claremont, North Carolina; Cincinnati, Ohio; and Williamsport, Pennsylvania. Fiber optic cable tends to come from Claremont in our orders. Power cable more often comes from Cincinnati. Williamsport shows up on control and instrumentation cables.

'Where is Prysmian cable made?' is not a trick question, but it has layers. If a project requires domestic content, don't rely on the brand. Check the certificate of origin for the exact plant. I've rejected a shipment because the quote said 'US-made' but the documentation listed a non-domestic component. The plant mattered for compliance, not just preference.

What does 'Prysmian acquires Encore Wire' mean for buyers?

Prysmian announced the acquisition of Encore Wire in 2024. It was reported as roughly a $3.9 billion deal. Encore is a major U.S. manufacturer of copper building wire, based in McKinney, Texas. For buyers, the headline change is simple: one company now owns both Encore's standard building wire and Prysmian's specialty cable portfolio.

In practice, it means you may be talking to one supplier about a broader set of needs than before. It also gives Prysmian more U.S. production capacity, which can shorten lead times for common wire products. You may also see Encore product names continue on labels for a while. Corporate rebranding usually lags behind the legal deal. I learned that in 2024, and it's still true in early 2025. If you're managing an approved vendor list, ask current vendors whether they're distributing the combined catalog yet. Don't assume. For the exact status, check Prysmian's investor releases.

Why do I see 'Prysmian Holdings' on invoices?

Basically, large manufacturers organize legal entities through holding companies. In the U.S., a lot of Prysmian-related contracts and invoices run through an entity called Prysmian Holdings Inc. That's normal. The product you're buying hasn't changed. The legal entity on the contract may be a holding company, not the brand name.

I didn't fully understand this until a vendor payment got delayed because the invoice name didn't match the purchase order. That's the kind of thing that sounds like an accounting problem but becomes a supplier relationship problem. So don't let your team reclassify Prysmian as a different company when they see 'Holdings.' Verify the entity, add it to your approved vendor list, and move on. Honestly, I'm not sure why the corporate name still appears on some commercial paperwork while the parent brand appears on others. My best guess is that legal entities change at a slower pace than marketing.

Are Prysmian enclosures worth specifying?

Prysmian's cable accessory catalog includes enclosures, cleats, and termination systems. When someone asks about 'Prysmian enclosures,' I think of cable joint closures and protective termination cabinets. The name alone isn't enough.

What matters is whether the enclosure matches your cable construction, the installation environment, and the re-entry requirements. In Q1 2024, we had to swap out a batch of generic fiber closures because the cable entry grommets didn't fit our double-jacket cable. If the spec had called out the exact Prysmian kit, we would have caught it in the submittal instead of during installation. Not ideal, but workable.

So, worth specifying? Yes, when the catalog number is tied to the cable spec. No, if you're just choosing a brand because it sounds established. Match the components on paper first.

What is VSRX cable, and when do I need it?

VSRX is Prysmian's product family for fire alarm and life safety circuits. I don't know exactly what the letters stood for originally—I keep meaning to ask someone who was there. But their real job is to maintain circuit integrity in a fire. Standard plenum cable won't do that. If a fire alarm notification system has to keep operating while the building burns, the cable has to be rated and listed for that purpose.

The important thing to understand: 'VSRX' is a specific product code, not a generic cable type. If you see it on the engineer's drawings, use that exact family or get an explicit approved substitution. We had a spec violation in 2023 when a contractor brought in a lower-cost 'equivalent' without the correct listing. The AHJ caught it. That's a re-pull and a schedule hit nobody wants. If you work in healthcare, high-rise, or any site with life safety systems, this product family is worth understanding before the spec lands on your desk.

Is Prysmian the right call when my deadline is tight?

If the deadline is fixed and the project has real consequences, certainty matters more than the price per foot. In March 2024, we paid an expediting premium on a high-voltage cable order because the standard lead time would have blown an outage window. The premium was maybe 15% of the cable cost. The alternative was missing a maintenance window that had been scheduled for months. There wasn't really a contest.

Does that mean Prysmian is always faster? No. It means their range is wide enough that you can usually find a specific SKU with a real lead time instead of a guess. When a supplier says 'should ship by Friday,' that's not a plan. Get the commitment in writing. Paying for guaranteed delivery is buying one thing: certainty. I'm not saying ignore price. I'm saying compare price after lead time, not before. Most of the time, certainty is worth it.
