Sigma Engineering was established in 1988, representing ABB in Egypt, and providing supply, engineering, and maintenance of ABB UPS and ATS products. Gradually, the company enhanced its portfolio and added various other power quality products, and represented more European companies (e.g. Gustav Klein, Aerocom and Eaton).

The company also provides comprehensive maintenance contracts, as well as consultation services in the areas of power quality and green energy transformation. Read More
