The acquisition of Ohio Brass® in 1978 was Hubbell® Incorporated's first foray into the power systems sector. Today, Hubbell Power Systems, Inc. (HPS) manufactures Ohio Brass polymer and porcelain insulators and arresters used in the transmission, substation and distribution markets. Our designs include suspension, station and line post, as well as polymer insulator and arrester combinations for lightning protection. Ohio Brass was founded in 1888 in Mansfield, Ohio. Today, HPS continues to manufacture these legacy products in Wadsworth, Ohio along with our Aiken, South Carolina location.
