About Marmon Utility LLC
Marmon Utility LLC is headquartered in Milford, New Hampshire, and operates as part of the Marmon Group of Companies, a Berkshire Hathaway company. The business brings together the Hendrix and Kerite brands, which collectively represent over 200 years of experience in power cable, spacer cable systems, and polymer insulators. Hendrix has more than 70 years designing and manufacturing aerial covered cable systems for distribution and transmission circuits from 15 kV to 115 kV, while Kerite Cable Services has over 30 years delivering turnkey engineering and installation for 15 kV to 138 kV cable systems. The company designs, engineers, manufactures, and installs a range of products including Hendrix aerial covered cable systems, polymer insulators and molded accessories, TR‑XLPE medium‑voltage underground cable (15–35 kV), and Kerite DR‑EPR medium‑ and high‑voltage cable (5–138 kV). Its services span responsive engineering, on‑site installation assistance, circuit design and review, project management, system testing, and ongoing training. Marmon Utility serves customers across 50 states and seven continents, with installations noted in Antarctica and a renewable‑energy microgrid on Saona Island in the Dominican Republic. Primary customers are electric utilities and power‑infrastructure operators needing overhead and underground cable solutions for distribution, transmission, substation, and subsea applications. The Saona Island project, which brought 100 % renewable power to a 100‑square‑kilometer island, illustrates the company’s reach in renewable‑energy integration. Marmon Utility emphasizes its Rapid Cycle Time program for the shortest and most consistent lead times in the industry, a corona‑resistant insulation system that prevents treeing in Kerite cable, and HDPE polymer insulators guaranteed for life and made in the USA. The backing of Berkshire Hathaway provides financial stability for long‑term partnerships.
