  • Rubadue Wire is pleased to announce the integration of Kerrigan Lewis manufacturing and sales/customer service into the Rubadue Wire Colorado facility. Kerrigan-Lewis is excited about this addition and the ability to better service the custom base of both companies.
    Kerrigan-Lewis joins Pelican Wire Company of Naples, Florida, and Rubadue Wire of Greeley, Colorado under the Pelican Holdings Group umbrella.
    Pelican Wire Company is a custom manufacturer of wire and cable products used for electrical heating and temperature measurement. Specializing in resistance wire, thermocouple wire, and custom wire, Pelican has the capabilities to deliver on any wire and cable need.

    Greeley, Colorado based Rubadue Wire is a pioneer in the wire and cable industry having created the world's first triple insulated wire and developed the self-bonding fluoropolymer product line known as COILBOND. The Company has since expanded into a variety of multi-layer insulated wires and other value-added solutions in the wire and cable industry.

    Kerrigan-Lewis Specialty WireChicago, Illinois based Kerrigan-Lewis is a pioneer in the manufacture of Litz wire used for high frequency electrical applications. They are well known for their quality Litz products, including served yarn and nylon insulations.

    Typically, the design engineer requiring the use of Litz knows the operating frequency and RMS current required for his application. Since the primary benefit of a Litz conductor is the reduction of AC losses, the first consideration in any Litz design is the operating frequency. The operating frequency not only influences the actual Litz construction, it also determines the individual wire gauge.

    Kerrigan-Lewis litz wire is available in a wide range of configurations to meet specific operating frequencies, voltages, and current-carrying capacities. Individual strands range from 50 to 16 AWG, with anywhere from a few strands to thousands in the wire.
