Kerite Company

Kerite Company is an American cable manufacturer and installer headquartered in Seymour, Connecticut. Founded in 1854 by Austin Goodyear Day, a nephew of Charles Goodyear, the company belongs to the early history of insulated electrical-cable production in the United States. Its business has centered on cables used in power transmission, communications-related infrastructure, and demanding industrial environments. The company’s best-known offering is high-voltage cable for power-transmission systems. According to the company description summarized in reference material, Kerite produces cable for voltage ratings from 46 kV through 138 kV. Its product range also includes specialty medium- and high-voltage cable intended for underwater and water-exposed installations. Such applications include subsea work, flooded utility vaults, water-soaked conduits, and locations with high groundwater levels, where resistance to moisture and difficult installation conditions is important. Kerite’s historical project references include the installation of a power cable beneath New York Harbor in the late nineteenth century and the supply of cable for the Panama Canal in the early twentieth century. These projects associate the company with major infrastructure construction during periods when electrical networks and large civil-engineering works were expanding rapidly. The Panama Canal reference is particularly relevant to Kerite’s later positioning around cable for harsh or wet environments. In addition to transmission and specialty cable, Kerite manufactures electrical submersible-pump cable. This product is designed for high-temperature environments, wells, down-hole applications, and the mining and drilling industries. The offering extends Kerite’s capabilities beyond conventional grid cable into specialized industrial power delivery, where cable must operate in confined, hot, wet, or mechanically demanding settings. Kerite’s ownership history includes acquisition by the Hubbell Company in 1969 and acquisition by the Marmon Group in 1999. Marmon was controlled by the Pritzker family at the time of that transaction; Kerite subsequently became part of Berkshire Hathaway through Marmon’s ownership structure. The company is privately held rather than publicly traded. Although its products serve infrastructure and industrial customers, Kerite is primarily a specialist manufacturer rather than a consumer-facing brand. Reference material identifies it as an operating company that manufactures and installs power cables from its Connecticut base.

Kerite Company was established in 1854 by Austin Goodyear Day, who was a nephew of Charles Goodyear. Its origins place it among the early American enterprises involved in the development and manufacture of insulated electrical cable. Over time, Kerite became associated with cable for power transmission and other infrastructure applications rather than with consumer electrical products. The company’s historical significance is reflected in major infrastructure projects attributed to it. In the late nineteenth century, Kerite installed a power cable beneath New York Harbor. The project represented the engineering challenges of placing electrical infrastructure below a major body of water at a time when urban power systems were expanding and cable insulation technology was still developing. In the early twentieth century, Kerite also supplied cable for the Panama Canal. That application helped establish a continuing association between the company and cable intended for wet, difficult, or otherwise severe operating environments. Kerite’s later product scope included high-voltage cable for power-transmission systems, with reference material identifying a range from 46 kV to 138 kV. The company also developed or manufactured specialty medium- and high-voltage cable for underwater installations and locations affected by groundwater, flooded utility vaults, or water-filled conduits. These products address environments in which ordinary cable systems may face unusual exposure to moisture and installation constraints. The company expanded its industrial relevance through electrical submersible-pump cable. These cables are intended for use in high-temperature settings, wells, and down-hole operations, including applications in mining and drilling. This line complements Kerite’s transmission products by serving specialized energy and extraction environments where electrical equipment must operate at depth and under demanding thermal and environmental conditions. Kerite’s corporate ownership changed during the second half of the twentieth century. Hubbell Company acquired the business in 1969. In 1999, the Marmon Group acquired Kerite. Marmon was controlled by the Pritzker family at that time and later became part of Berkshire Hathaway. Kerite consequently operates within the Berkshire Hathaway group through Marmon’s ownership structure while remaining a private industrial business. Henry C. Spencer began working at Kerite in 1951 and retired as vice president in 1978, providing one documented example of the company’s long-term managerial continuity. Reference material identifies Kerite as based in Seymour, Connecticut, where it manufactures and installs power cables. Its current profile is that of a focused industrial supplier serving utility, infrastructure, subsea, and specialized energy-sector requirements.
