LS Cable's first EU busduct plant triples capacity as AI data center power hunger grows

When we talk about AI infrastructure in 2026, the conversation usually starts with GPUs, moves to memory bandwidth, and ends at token prices. But every token a model generates is physically powered through a chain of transformers, switchgear, and prefabricated power-distribution rails most people have never heard of. One of those rails is the busduct — and it has quietly become one of the most strategic components in the AI supply chain. South Korea's LS Cable & System, one of the largest power-cable and equipment makers in the world and part of the LS Group, is pursuing its first European busduct plant, according to finance.biggo.com. The project would roughly triple the company's busduct production capacity, and the stated driver is Big Tech's AI investment wave.

What a busduct actually does

A busduct — also called a busway or busbar trunking system — is a factory-made, modular way to distribute electrical power. Instead of pulling dozens of individual cables from a transformer to each row of racks, installers bolt together sections of enclosed copper or aluminum busbars. Compared with conventional cabling, busways install faster, take up less space, and carry far higher currents. Most importantly for data centers, they are modular: when racks move or power loads change, sections can be added or relocated without ripping out cable trays. AI is the reason this matters right now. A traditional enterprise rack draws 5–10 kilowatts. An AI training rack with eight H100-class GPUs needs 10–15 kW. Liquid-cooled, high-density AI systems such as Nvidia's GB200 NVL72-class servers are rated around 120 kW per rack, and hyperscalers are announcing AI campuses measured in gigawatts.

Doing the power math

Here is a back-of-the-envelope calculation that explains the investment. A large busway — 6,300 A at 400 V three-phase — can carry about 4.4 MVA. At a typical 0.95 power factor, that works out to roughly 4 MW of usable IT power per run. A 1 GW AI campus, the scale of several projects already announced, would thus need hundreds of these busway runs for IT loads alone, plus additional distribution for cooling, lighting, and the rest of the facility. Seen from that angle, a manufacturer tripling its busduct capacity is not an aggressive bet — it is simply catching up with orders that already exist.

Why Europe, and why now

The most interesting part of this story for European readers is that the plant is planned for Europe in the first place. Europe is not the world's largest data center market — the United States still holds that title — but it may have the most complicated power politics. The traditional hubs — Frankfurt, London, Amsterdam, Paris, and Dublin, the so-called FLAP-D markets — face serious grid constraints. The Netherlands and Ireland have at times restricted new data center connections, and Germany has had to accelerate grid investment to keep up with AI-era demand. Add the EU AI Act, whose enforcement is now fully active (GPAI obligations since August 2025; high-risk system obligations since August 2026), and the EU's push for in-region, sovereign AI capacity via its AI Factories initiative, and you get a structural demand for compute that physically has to live in Europe. That demand brings a specific need: European data center builders want power-distribution equipment that arrives quickly, complies with European standards — busbar trunking in the EU falls under IEC 61439-6 — and does not depend on a container ship idling in a port for months. A local LS Cable plant shortens lead times dramatically and removes a chunk of supply-chain risk. It also sends a quieter signal: major Asian manufacturers now treat Europe's AI buildout as a market worth local factories, not just exports.

The competitive landscape

LS Cable is not stepping into an empty hall. Siemens, Schneider Electric, Legrand, Vertiv, and ABB all sell busway systems, and Schneider's I-Line Track Busway and Siemens' busbar trunking are common sights in European facilities. What makes this move notable is the scale and timing: entering a foreign market with a dedicated plant for a single product line, and tripling overall capacity in the process, is a firm bet that demand will not soften. It also fits a broader pattern. Several Asian power-equipment and component makers have been localizing production in Europe over the past two years, partly to serve local markets and partly to hedge against growing scrutiny of critical supply chains. Power equipment is not semiconductors, but it is close enough to critical infrastructure that no serious player wants to be caught short.

What it means in practice

For European companies building AI capacity — from hyperscalers constructing gigawatt campuses to regional operators bringing up 10 MW GPU clusters in Poland or Spain — the practical effect is about lead times, choice, and price. More local supply means shorter procurement timelines and more pressure on incumbents to stay competitive. For the rest of us, the busduct is a useful reality check. Here at ai-jarvis.eu, we spend a lot of time measuring tokens per second, time-to-first-token, and VRAM usage on our RTX 5060 Ti rig in AI Arena. But none of those benchmarks exist without dependable power distribution behind the building. Every model we test, every API call we time, is downstream of exactly the kind of equipment LS Cable just bet a European factory on. The quiet infrastructure of AI is where the industry's real constraints live right now. A Korean cable maker tripling its capacity a continent away from home is as good a sign as any that the constraint is real.
