Keveloc® puncture resistant laminates provide cut-through resistance to areas under compression or shear forces.
Often in industrial machinery and stator coils, these thin, yet extremely durable Keveloc® Laminates act as insulation between layers of machinery. Preventing long-lasting damage and eliminating the need for re-insulation when coils are prone to strand-to-strand shorts with aramid or mica insulations.

While pushing the limits of design and manufacturing capabilities to increase power density and lower losses, it quickly became apparent that our manufacturing technologies needed to be more robust to keep up with new complexities within the stator bar designs. KevelocTM, the roebel transposition insulation materials provided by Puncture Resistance, enabled our manufacturing team with the capability to achieve more complex transposition geometries without affecting bare bar build, electrical integrity, or cost. The flexibility to fabricate the material in different dimensions and orientations made a very complex design simple and easy to manufacture. We are thankful to have a great product and supplier for a fast and effective solution! Thank you Electrolock Team for all that you do!
I have worked for a major manufacturer of rotating equipment for over 40 years in the development of special insulation applications to high voltage generator components. One of many examples is the design, testing and implementation of stator strand insulator using KevelocTM as the base insulating material. The development process involved Electrolock, design engineering for OEM manufacturing, along with manufacturing engineering in creating the material design and supply. A butterfly strand insulator was developed with help from Electrolock. Where Roebelled strands crossover in the crimp regions, strand to strand shorts may occur. The butterfly crossover insulator prevents these shorts, thus allowing the coil to meet the design criteria requirement of no strand to strand shorts. This product from Puncture Resistance has reduced manufacturing cost as well as improved product costs.
Keveloc® is a cut-resistant laminate design with a high resistance to puncture or tear from an object forced through its z-axis. To determine resistance to puncture and tears through its z-axis, we used several ASTM testing methods.
We have a full analytical and high voltage test lab capable of testing to a large variety of standards. Contact us today to discuss your specific requirements.
