Products
What we build
Our water-cooled flexible power cables, high-current bus systems, delta closures, bus tubes, electrode holders and other specialty copper components are preferred by many of the world's leading engineering firms.
Flexible power cables
From small induction furnace leads to the world's largest arc furnace cables. We repair all brands to meet or exceed OEM specs.
Water-cooled copper panels
Panels in any configuration for any type of furnace, plus evaluation, repair and rebuild of existing panels.
Lance tips & burners
Precision machined, forged copper lance tips and oxy-fuel burners to replace those made from castings.
Specialty copper components
We can design, build or repair any copper part used to carry high and ultra-high electrical current.
Shunts & jumpers
Laminated and braided flexible copper shunts, plus water- and air-cooled copper jumpers built for the lowest possible resistance.
1956
In 1956, Nu-Core engineers developed the basic elements of water-cooled, high-current secondary electrical systems, a technology that is now an industry standard for the efficient transfer of ultra-high-current transmission throughout the world.
When higher-current bus systems became necessary in the 1960s, water-cooled bus applications followed, and Nu-Core was one of the early pioneers in the field. Nu-Core engineers also pioneered rope lay cable construction, now the worldwide standard for high-current AC and DC power applications.
Services
From drawing to on-site repair
Design & engineering
CAD/CAM technology for complete design solutions, from detailed engineering drawings to organizing information for field installations. Each component is custom designed to fit your system.
Fabrication
CNC machining, copper welding and fabrication done in-house, so we can build a high-current bus system to your specifications in the shortest possible time.
Repair
In our factory or on-site, with service technicians available 24 hours a day, 365 days a year to minimize your downtime.
Inventory
Materials on hand for emergencies
Because shutdowns are costly, we keep an extensive on-site inventory. If an emergency shutdown occurs, we have the materials in stock to get your equipment running again as quickly as possible.
