Switzerland-based Weidmann Electrical Technology is investing $155 million to expand its Ohio operations through the redevelopment of a 350,000-square-foot brownfield site in Middletown. It will bring dozens of new jobs to the region.
The new Middletown facility will feature a next-generation production line for "transformerboard," a material used in the manufacturing and long-term reliability of power transformers. Transformerboard was developed by Weidmann in 1937.
At the same time, Weidmann’s existing Urbana facility, located northeast of downtown Dayton at 700 W. Court St., will expand to support the Middletown operation and meet growing demand for the specialized insulation paper products it manufactures. Together, these investments will enhance domestic supply chain resilience and support global demand for electrical transformer insulation.

"This reinvestment in a historic manufacturing facility strengthens our growing, business-focused ecosystem while solidifying our industrial legacy across the region,” said Ashley Combs, Middletown city manager. “The Butler County Land Bank and JobsOhio were crucial in helping Weidmann Electrical Technology find a home here in Middletown, bringing new job opportunities to our residents and providing the company with access to a large regional workforce."
