Was Cooper Power Systems Power Transformers ( asbestos documented in litigation?

Cooper Power Systems Power Transformers ( is documented in public asbestos litigation records as a manufacturer whose products contained asbestos during the mid-twentieth century. Workers in industrial facilities, power plants, refineries, shipyards, and commercial construction who handled or worked near these products may have experienced occupational exposure.

Which trades had the most exposure?

Pipe coverers and insulators, pipefitters, boilermakers, millwrights, and maintenance workers are among the trades most frequently documented in asbestos exposure claims. Workers who cut, fitted, or removed asbestos-containing products — and those working in close proximity during that work — typically had the highest fiber concentrations.

How long do workers have to file an asbestos claim?

Statutes of limitations for asbestos personal injury claims vary by state, typically ranging from one to five years from the date of an asbestos-related diagnosis. The clock generally starts at diagnosis, not exposure — mesothelioma can have a latency period of 20 to 50 years. An asbestos attorney can identify the deadlines that apply to your specific situation.

Can workers file claims related to Cooper Power Systems Power Transformers ( asbestos exposure?

Yes. Workers diagnosed with mesothelioma, asbestos-related lung cancer, or asbestosis after exposure to Cooper Power Systems Power Transformers ( products may pursue claims through civil litigation. An experienced asbestos attorney can assess available defendants, applicable trust funds from co-defendants, and the states where claims can be filed most effectively.

Can family members file secondary exposure claims?

Spouses, children, and household members who developed asbestos-related disease through contact with contaminated work clothing brought home by an exposed worker may be eligible for secondary (household) exposure claims. Wrongful-death claims can also be filed by surviving family members of workers who died from asbestos-related disease.

Overview Product Facts Trades

Litigation Record: Information below reflects allegations in publicly filed asbestos litigation — plaintiff allegations, not findings of fact.

Manufacturer Background

Cooper Power Systems is the power-transformer business unit of Cooper Industries, allegedly formed through Cooper’s 1985 acquisition of McGraw-Edison Company (including the McGraw-Edison Pennsylvania Transformer Division at Canonsburg, PA) and Cooper’s broader U.S. transformer-business consolidation. Cooper Power Systems allegedly operated multiple power transformer manufacturing plants in Waukesha, Wisconsin from 1992 onward, producing large utility-scale power transformers, distribution transformers, and pad-mount transformers. Per publicly filed allegations in U.S. asbestos litigation, Cooper Power Systems transformers and related electrical-distribution products allegedly incorporated asbestos-bearing components consistent with industry practice in the late asbestos era, and Cooper Power Systems facilities allegedly serviced aged transformers from the 1950s-1980s asbestos manufacturing era.

How Workers Were Exposed

Per publicly filed allegations in U.S. asbestos litigation, workers were allegedly exposed to Cooper Power Systems / Cooper Industries asbestos-bearing transformer components during:

Transformer assembly at Cooper Power Systems / Cooper Industries 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 Cooper Power Systems / Cooper Industries 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 Cooper Power Systems / Cooper Industries transformers during in-service repair
Reconditioning operations — heat-baking, vacuum drying, and oil refilling of disassembled transformer units saturated with asbestos fiber

Documented Servicing Locations

Cooper Power Systems / Cooper Industries power transformers manufactured during the asbestos era were allegedly serviced, dismantled, and rebuilt at the Westinghouse / ABB transformer service centers in St. Louis MO, Detroit MI, Chicago IL, Louisville KY, Houston TX, Cedar Rapids IA, Omaha NE, Wichita KS, and Cleveland OH (as well as at GE service centers and independent transformer-rebuild shops). Asbestos-bearing components common across all major U.S. transformer brands include phenolic spacers, Westinghouse Micarta laminate, Bakelite-type laminate, asbestos paper, asbestos cloth, asbestos gaskets, and phenolic-asbestos bushings.

The occupational health risks associated with asbestos inhalation are well established under OSHA standards and documented by regulatory bodies including the EPA. Diseases associated with asbestos exposure include mesothelioma, asbestosis, lung cancer, and other asbestos-related conditions, which may have latency periods of decades between initial exposure and clinical diagnosis.

Legal Considerations

Workers exposed to Cooper Power Systems / Cooper Industries power transformers at any U.S. transformer manufacturing plant, transformer service center, utility substation, or industrial facility may have legal rights if they have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease.
