Power cables for AI and high-density data centers

By one of the leading data center cabling companies in the U.S.

Nassau National Cable is a U.S.-based bulk cable distributor and one of the most prominent data center cabling companies serving mission-critical construction projects nationwide. We supply large volumes of power distribution wire, medium-voltage cable, and control cable with cut-to-length service, multi-manufacturer sourcing, and a supply chain built to keep your electrical installation on schedule.

What NNC Offers as a Data Center Cable Supplier

NNC operates as both a primary (first-line) and supplemental (second-line) supplier for high-volume, multi-phase AI and high-density data center projects. We work with data center owners and operators, EPC and GC firms, procurement and sourcing teams, and infrastructure engineers.

Large-Volume Availability

Scalable inventory of aluminum and copper power cables across multiple manufacturers. Typical order volumes run 10,000–300,000 ft, scalable beyond on request.

Short Delivery Timeframes

Cut-to-length services and nationwide fulfillment. High-volume orders ship in weeks, matched to the pace of mission-critical construction timelines.

Primary or Backup Supplier

Qualified to serve as a first-line supplier for full-scope cable delivery, or as a pre-approved secondary supplier when a primary vendor can't deliver, or the scope expands mid-project.

Supply Continuity & Risk Reduction

Multi-manufacturer sourcing and inventory planning to avoid reliance on a single source. Risk controls include backup sourcing, split-order fulfillment, and inventory transparency.

Phased & Staged Delivery

Cable selections and fulfilment schedules are coordinated to accommodate expansion without disrupting supply continuity. Phased and multi-site delivery available on request.

Code & Standards Compliance

Cables supplied with full documentation and traceability. Aligned with NEC, UL, and data centre infrastructure standards, including TIA-942-C, ISO/IEC 11801-5, and ANSI/BICSI 002.

Execution Snapshots

Cables supplied with full documentation and traceability. Aligned with NEC, UL, and data centre infrastructure standards, including TIA-942-C, ISO/IEC 11801-5, and ANSI/BICSI 002.

AI Data Center Developer

Lead supplier for a high-priority, liquid-cooled supercomputing cluster on an aggressive schedule. Managed phased, staged delivery of armored power and tray cables throughout the build.

Data Center Equipment Manufacturer

Stepped in when the original vendor couldn't deliver. Supplied high-volume copper feeder cable to keep the installation moving and prevent an expensive shutdown.

National Research Laboratory

Multi-phase R&D project with complex commissioning windows. Timed high-voltage aluminum and control wire deliveries to align with the lab's specific testing schedule. Snapshots are representative. Client names withheld under standard procurement confidentiality.

We make sure your cable plan doesn't break your project timeline.

Cable procurement is a critical path item in every data centre build. A single delayed shipment stalls the entire electrical installation. NNC is structured to prevent that.

Multi-Manufacturer Sourcing

We source across multiple manufacturers, so your supply isn't tied to a single production line. If one manufacturer has a lead-time issue, we pivot to an equivalent, qualified source without disrupting your schedule or spec compliance.

Lead Time Risk Mitigation

Medium-voltage feeders and large-gauge copper are the items most likely to delay a project. We identify these early, confirm stock or production availability upfront, and can hold inventory against your construction schedule before you need it on site.

Flexibility as Scope Changes

Data center projects expand mid-build. When the scope increases, we can absorb the additional volume and adjust the delivery cadence without requiring a new procurement cycle.

Procurement Alignment

We work from your cable schedule and construction milestones. Phased and staged delivery models are coordinated with your pull sequence, so cables arrive exactly when your crew needs them. Share your cable schedule or project scope, and we will respond with pricing and confirmed lead times.

MV105 500–1000 MCM · 5KV–35KV · EPR · 105°C

Medium-voltage primary distribution. Used for underground runs and high-ambient installations where EPR's flexibility and heat tolerance matter.

MV90 350–1000 AL · 35KV · XLPE · 90°C

Cost-effective medium-voltage feeder for standard high-density environments. XLPE insulation handles typical campus distribution loads well.

XHHW-2 Cu or AL · 600V · XLPE · heat & moisture resistant

Primary feeder cable in wet or high-temperature locations. Frequently specified for conduit runs serving UPS and PDU equipment. Common in AI data centers.

XHHW-2 Cu or AL · 600V · XLPE · heat & moisture resistant

Primary feeder cable in wet or high-temperature locations. Frequently specified for conduit runs serving UPS and PDU equipment. Common in AI data centers.

MC Cable Cu or AL · 600V · aluminum interlocked armor

For branch circuits in dense server environments. Armored construction provides mechanical protection where rigid conduit won’t cut it.

Tray Cable (TC / VNTC) TC-ER · 600V · THHN insulation · PVC jacket

For power, control, and signal circuits routed in open cable tray systems across the data hall floor or overhead ladder rack.

SOOW 600V · flexible · oil & water-resistant rubber

For temporary and portable power connections during construction, commissioning, and testing phases.

Type W 2000V · heavy-duty · extra-flexible rubber

For temporary and portable power connections during construction, commissioning, and testing phases

DC Power Cable Configuration varies by project

Backup battery systems, VRLA and lithium-ion UPS banks, and DC distribution racks in hyperscale deployments.
