30 Wire & Cable ASIA – September/October 2014
Industrynews
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
processes, and forming plant
engineering, and organises the
MEFORM conferences on materials
production and processing
technologies. The next MEFORM will
take place from 25th to 27th March
2015.

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
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.
