ABB will design, supply and build 24 sets of high-power diode rectifier systems for four aluminium pot lines.Tom Sjoekvist, head of ABB’s automation products division, said: ‘ABB automation and electrical systems will become the manufacturing backbone of this smelter plant.‘The combination of standard ABB products and systems and our primary metal and minerals expertise creates an unbeatable offering for our customers in terms of productivity, reliability and energy efficiency.’It is hoped production capacity of aluminium ingots, rods and rolled products will double when the expansion is complete.ABB’s scope of supply also includes a new 400 / 220 kV switchyard, designed to supply the new smelter plant with reliable power, as well as a process control system with fibre optic current sensors. In addition an ABB MicroSCADA control system has been specified for the power distribution network, substation switching bays, power and station transformers.In 2007-08 ABB was involved in phase one of the Jharsuguda plant expansion, supplying rectifier systems. When phase two is complete in 2009, Vedanta predicts its total aluminium smelting capacity will be approximately 1,700,000 tonnes per year.
