Nano-Technology Lab

Carbon Nanotube Lab

At Minnesota Wire our research and development efforts are helping drive the industry into the future. Our research with CNTs (carbon nanotubes) is helping us create wires and cables that are substantially lighter and more resistant to heat and interference than conventional metallic conductors.

Minnovate, our research and development division, boasts a rare piece of equipment called the RESS reactor (Rapid Expansion of Supercritical Solutions). The RESS enables us to test conductive CNTs on virtually any surface. (The RESS reactor utilizes supercritical carbon dioxide as the solvent to allow for the dispersion of carbon nanotube powder into an appropriate polymer medium for spray applications.)

Minnovate is leading the market in design and manufacturing versatility.

Mechanical Test Lab

Minnesota Wire’s Mechanical Test Lab is utilized for static and dynamic pull testing, cable flex testing, and water ingress measurement. We execute rigorous tests to guarantee the product will meet your specifications and perform to your requirements.

Signal Integrity Lab


Signal integrity should begin at the design and engineering phase of every project. Schematics should be drawn before any cable is created in order to ensure against signal integrity problems being designed into the product.

Our design engineers will work with you to ensure that every signal reaches its destination in the time required, without distortion or interference from other signals, and without creating any disturbance of its own.

Our 50 years of experience means that our wires and cables have been tested in the field in every imaginable situation. We are proud to say that Minnesota Wire’s interconnect products have continually delivered under the harshest of conditions.
