 335311 Power, Distribution, and Specialty Transformer Manufacturing

This U.S. industry comprises establishments primarily engaged in manufacturing power, distribution, and specialty transformers (except electronic components). Industrial-type and consumer-type transformers in this industry vary (e.g., step up or step down) voltage but do not convert alternating to direct or direct to alternating current.

Cross-References. Establishments primarily engaged in manufacturing electronic component-type transformers are classified in U.S. Industry 334416, Electronic Coil, Transformer, and Other Inductor Manufacturing.
