Alcan Extrusions and Automotive Structures supplies 100 km of Energy Saving Aluminium Power Rail for the New Metro in Bangalore
Alcan Extrusions and Automotive Structures, part of Alcan Engineered Products - a business unit of Rio Tinto - has been granted a contract to supply 100 km of aluminium power rail for a new metro project in the Indian metropolis Bangalore. Deliveries over a period of 24 months have started in June 2010
In addition to the production of the aluminium power rail system, Alcan will also provide an engineering and service package through the Railtech-Alu-Singen Joint-Venture. This Joint-Venture, founded by Alcan Singen GmbH and Railtech International in 2003, is a recognized global market leader in the segment of aluminium power rail solutions.
“The field for aluminium power rails is a growing market with a great potential. The global demand for means of transport is increasing and many cities are extending their existing subway net or planning new lines,” said Paul Warton, President of Alcan Extrusions and Automotive Structures, and added: “significant energy savings can be achieved by the use of the high electric conductivity of aluminium.”
Power rails (conductor rails) are used as contact line systems. The electrical power is transferred from substations to the rolling stock through a collector shoe located on the superstructure of the train vehicle. The power rail consists of an aluminium body for electrical conduction and a stainless steel inlet providing the required abrasion resistance. The two different materials are extruded together in a complex co-extrusion process, which is unique for this type of application. Aluminium provides a lower specific electrical resistance, an improved conductivity and a largely reduced weight compared to a soft iron solution only.
By 1000 km of aluminium power rails installed, compared with steel rails, about 700,000 tonnes of green-house gas will be saved during a life time of 30 years. One kg of aluminium used in rails saves about 37 kg of green-house gas and is afterwards recycled to new aluminium.
The City of Bangalore has decided to build this DC powered railway system to relieve the high level of traffic congestion currently experienced. This sub-urban train will consist of two completely new rail lines mainly to be built on stilts.
