American Electric Technologies (AETI) tames wild and woolly wiring. It operates through three segments: technical products and services (nearly 60% of sales), electrical and instrumentation construction (about 35%), and American Access. Technical products and services makes low- and medium-voltage switchgears for land- and offshore-based oil and gas drilling, as well as refineries and municipal power companies. The electrical and instrumentation construction unit makes electric power delivery and control products and provides technical field services and electrical and instrumentation construction services. American Access makes zone-cabling cabinets for telephone lines, data networking, and security systems.
