Driven by a vision to pioneer, ASC has risen from its humble beginning more than 25 years ago of a sole factory for LV boards, to an organisation boasting of 11 factories managing LV & HV Switchgear, Transformers and Package Sub-stations, establishing itself as the largest power equipment manufacturer in the region.

ASC takes pride for being the leading local manufacturer of HV products, transformers and package S/S. Over time, ASC products have attained a reputation for quality, reliability as well as sustainability which gained recognition in the industrial sector in the Middle East.

All products have been developed inside the walls of the factory and will continue to improve, because progress stops once the spirit of pioneering is lost.
