NAICS Code 335311 Power, Distribution, and Specialty Transformer Manufacturing

Industry

Manufacturing

Description

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, Capacitor, Resistor, Coil, Transformer, and Other Inductor Manufacturing.
