Messe Düsseldorf cheques in to help industry

THE wire 2014 and Tube 2014 trade shows are not only a forum where new manufacturing technologies are on display but also encourage the technology transfer between research and industry. Messe Düsseldorf, organisers of both trade shows, supports research institutes which are busy in this field and therefore a source of innovative ideas. In May, Friedrich-Georg Kehrer, director wire/Tube Düsseldorf, handed over a cheque for €10,000 to Prof Dr-Ing Rudolf Kawalla, director of the Institute of Metal Forming at the Freiberg University of Mining and Technology. The handover took place during an official ceremony on the occasion of re-opening the institute building after extensive renovation works. The donation will be used for the further development of bar, strip and rod forming processes with emphasis on energy and materials efficiency. The Institute of Metal Forming, whose origins go back to 1928, focuses on steel materials and light metals, especially magnesium, the characterisation of materials, the numerical simulation of forming

New edition of ‘Copper Busbars: Guidance for Design and Installation’

seeing increasing use in distribution panels and switchboards, but the design considerations for this application are significantly different from long vertical and horizontal busbars. It is a growing market since busbar profiles offer distinct advantages, such as material savings, lower assembly time, lower complexity and reduced scrap. Other chapters cover lifecycle costing, short-circuit effects and jointing techniques for busbars. An annex provides valuable information on busbar coatings, focusing on the reasons for coating them, methods of coating, inspection and maintenance. Busbars are used within electrical installations for distributing power from a supply point to a number of output circuits. They may be used in a variety of configurations ranging from vertical risers – carrying current to each floor of a multi-storey building – to bars used entirely within a distribution panel or within an industrial process.

The Copper Development Association first published the popular ‘Copper Busbars: Guidance for Design and Installation’ in 1936, and now a new edition adds significant content on busbar profiles and simplified formulae for busbar configurations. It will be of particular benefit to design engineers of electrical distribution systems seeking to design efficient, economic and reliable busbar systems. A total of 108 pages in length and available for free download, Copper Busbars is divided into six chapters. The introductory chapter focuses on materials for busbars, detailing the properties of a conductor material that are essential to achieve a long and reliable service life at the lowest lifetime cost. It reviews conductor materials for busbars and concludes that the required combination of properties is a very good match for copper. The book includes a completely revised chapter on current-carrying capacity. The book also features a brand new chapter on profiles. This content was added because busbar profiles are
