Wadsworth, Ohio |
Operating since: 1968

Our Frank B. Black Research Center in Wadsworth is home to Hubbell’s state-of-the-art High Voltage Test Lab. The facility was originally built the Ohio Brass Company to develop and test world- class insulators, surge arresters and cable accessories for underground systems. Today, arrester MOV block testing, mechanical and environmental testing happen here, along with polymer development.
