Dubai Aluminium, often called DUBAL, is a subsidiary of Emirates Global Aluminium (EGA). DUBAL was established and began operating in 1979. With continuous expansion projects over the years, DUBAL has grown significantly to become one of the world’s leading single-site primary aluminum smelters.
The DUBAL complex was built on a 4.75 square kilometer site in Jebel Ali, Dubai. It includes a 2,350 MW power station, a 1 million tpa smelter, a huge carbon plant, a water desalination plant, extensive casting operations (more than 1.2 million tpa), dock and other numerous facilities.
DUBAL is equipped with NORMABLOC Low Voltage switchboards which feed motors and which are protected and controlled by GemStart3 motor protection relays since 1998.
Due to successive expansions of its industry and leading by example to modernize its electrical switchboards with a cost effective and reliable solution, DUBAL approached COMECA Middle East, subsidiary of COMECA, to upgrade all its GemStart3 protection relays.
COMECA Middle East recommended to the customer the GemStart5-R retrofit kit, which consists of the replacement of all older versions of GemStart protection relays with the latest version of GemStart5 relays.
DUBAL has therefore awarded COMECA Middle East with the upgrade of 140 GemStart5 instead of the obsolete versions of GemStart3 in 6 different substations. Deploying its local team of experts, COMECA has successfully completed the target upgrade of 50% of the job in a very tight schedule. The remaining 50% of the job is planned to be completed during the next shutdown.
