HV Power Cables
High voltage power cable, 66kV and above up to 150kV XLPE-insulated classes, links grid substations and large transmission-scale loads. NLS sources HV cable to IEC 60840 on a project-specific basis, working from the utility or EPC contractor's technical spec since HV cable is always made to order and never a stock item anywhere in the region.
HV power cable sits above the medium voltage classes most industrial projects use, typically starting around 66kV and running up through 132kV and 150kV XLPE constructions. At this voltage level, cable design gets more particular: conductor screening, insulation thickness, and the outer metallic sheath (usually lead or aluminum, in addition to the copper wire screen) all have to control electrical stress precisely, and the joints and terminations become almost as engineered as the cable itself.
NLS sources HV cable against IEC 60840, the reference standard for 30kV to 150kV XLPE-insulated cable, working from whatever voltage class, conductor size, and route length the client's utility interconnection agreement or EPC contractor spec calls for. This isn't a category with common off-the-shelf sizes; every order gets confirmed against manufacturer capability and lead time before pricing goes out.
On Saudi projects, HV cable typically appears on grid interconnection works for large industrial facilities, utility-scale substations, and transmission-adjacent infrastructure, where the buyer is usually a utility, EPC main contractor, or specialized electrical subcontractor rather than a general project team. The documentation trail (type test certificates, routine test reports, and installation method statements) matters as much as the cable itself at this voltage class.
Given the specialized nature of HV cable, NLS treats every inquiry as project-specific: send the voltage class, conductor size, route length, and any interconnection standard referenced in the spec, and NLS returns a quote in USD with a lead time set by the manufacturer, since HV cable is never held as inventory anywhere in the supply chain and production runs are scheduled per order.

Frequently Asked Questions
What voltage range counts as HV cable?+
Generally 66kV and above, running through 132kV and 150kV XLPE-insulated classes referenced against IEC 60840.
Does NLS hold HV cable in stock?+
No. HV cable is made to order across the entire supply chain, not just at NLS. Every quote is built around confirmed manufacturer lead time once the specification is set.
Who typically buys HV cable on a Saudi project?+
Usually a utility, an EPC main contractor, or a specialist electrical subcontractor working on grid interconnection or large substation works, rather than a general project procurement team.
