Manufacturer Background

WEG Electric Corp. (and its U.S. transformer subsidiary WEG Transformers USA, Inc.) is one of the major U.S. and international power transformer manufacturers serving the U.S. utility and industrial electrical grid. WEG is named as a defendant in publicly filed U.S. asbestos litigation including the Duke v. CBS Corporation et al. case (Cause No. 1822-CC00339, City of St. Louis MO), where WEG Electric Corp. and WEG Transformers USA, Inc. appeared as defendants regarding asbestos-bearing transformer components allegedly handled by U.S. transformer service-center workers servicing WEG transformer products. Per publicly filed allegations, WEG-era and predecessor-brand transformer designs continued to be serviced, rebuilt, and reconditioned at U.S. transformer service centers for decades — meaning service-center workers handled WEG-built and predecessor-built transformers manufactured during the asbestos era.

  • WEG-built and predecessor-brand transformers serviced at U.S. transformer service centers nationwide

How Workers Were Exposed

Per publicly filed allegations in U.S. asbestos litigation, workers were allegedly exposed to WEG Electric asbestos-bearing transformer components during:

  • Transformer assembly at WEG Electric plants — handling phenolic spacers, asbestos paper, Bakelite-type laminate, gaskets, and asbestos cloth during new-transformer construction
  • Transformer dismantling and rebuild at service centers — extracting aged asbestos components from field-aged WEG Electric transformers (highest documented exposure category)
  • Coil-winding operations — fitting asbestos transformer paper and phenolic spacers during winding assembly
  • Machining and trimming — drilling, sawing, and finishing operations on cured phenolic and asbestos-bearing laminate
  • Field maintenance and substation service — utility substation electricians, lineworkers, and industrial electricians handling WEG Electric transformers during in-service repair
  • Reconditioning operations — heat-baking, vacuum drying, and oil refilling of disassembled transformer units saturated with asbestos fiber
