Southwest Electric Co.

What Southwest Electric Co. does

Southwest Electric Co. is a US-based custom electrical equipment manufacturer and service provider, founded in 1946 in Oklahoma City by three brothers as an electric motor repair shop and operating today as a wholly-owned subsidiary of Germany's SGB-SMIT Group following its Q1 2025 acquisition. The company designs and manufactures specialty liquid-filled transformers (25 kVA to 7,500 kVA), custom distribution transformers (padmount, substation, pole-mounted configurations from 37.5 kVA single-phase to 7,500 kVA three-phase), custom medium-voltage switchgear, and provides industrial motor repair services with capacity up to 100 tons, plus authorized distribution of TECO-Westinghouse and GE motors. A proprietary FACT (Full Amp Capacity Transformer) series addresses down-hole submersible pump and variable-speed-drive applications, and a new Power Transformer Division (manufacturing 2026, shipments 2027, up to 765 kV capability) extends the company into large power transformers.

The business operates from four facilities - Oklahoma City (corporate headquarters and transformers/motors plant), Tulsa (field services), Nashville, TN (industrial motors plus field services), and Louisville, OH (switchgear, integrated with SGB-SMIT's OTC subsidiary) - providing nationwide 24/7 field service coverage with 48-hour RFQ response. Revenue combines one-time custom equipment sales with recurring professional services (field testing, maintenance, oil processing, substation work from 5 MVA to 500 MVA) and managed services (spare motor storage with 90-day test cycles). All pricing is custom-quote based; no public pricing exists. Target verticals are electric utilities, oil & gas (FACT series), industrial plants, data centers (38kV switchgear), wind power, and water/wastewater municipalities.

Commercial model is direct enterprise field sales with engineering co-development, supported by an active industry events program (IEEE PES T&D, Permian Basin Oil & Gas Show, ECA, regional utility associations), content marketing, and social channels. Southwest Electric holds UL, cUL, IEEE C57, DOE 10 CFR 431.193, EASA, and SKF certifications, and is described as operating one of the largest motor repair facilities in the United States.
