Special steel wool fromMTB
There are currently four methods of wire purification after
scaling: mechanical cleaning by brushing; mechanical
cleaning by jetting; mechanical purification by peeling and
purification by using chemical aids.
However, Meier Technische Beratung has emerged with a
new development.
After breaking the scale the wire rod is run through
equipment in which six or eight fast rotating cleaning
units, loaded with pads of steel-wool, surround the surface
and take off parts of grain or dust.
The thin ropes of steel wool cause a scraping effect on the
surface of the wire but without damaging it because of the
weakness of the pad which adjusts itself to the surface,
and the surface of wire is smoothed in a very soft way.
The cleaning units are positioned in angles of 180° along
the working distance. This method gives a purified surface
and sets the wire in the best condition for further working.
There is no necessity for passivation.
In spite of the plant costs, the operation costs in total are
very low: no brushes, no tapes, no cutting tools, no acids,
only inexpensive pads of a special steel wool. The rubbish
can be recycled or disposed as waste.
The physical dates are not affected and the quality of
the wire is equal to the conditions after hot-rolling.
Additionally, the increasing temperature while working
causes relaxation to the wire rod.

FTTH additions from Prysmian
Prysmian Cables & Systems launched further additions to
its growing Fibre-to-the-Home (FTTH) product range at
CommunicAsia 2007 in Singapore from June 19th-22nd.
Optical fibre deployment in the access network continues to
gather pace in line with the rapid increase in global broadband
uptake, and Asia continues to lead the way in terms of
operational FTTH connections.
Visitors to CommunicAsia had the chance to see the latest
advances in telecoms and IT technology from 1,500 companies
from almost 60 countries.
Prysmian demonstrated the full range of its passive FTTH
portfolio including blown fibre, mini blown cable, pre-
connectorised customer solutions and a full range of optical
connectivity products.
Additionally it exhibited its latest addition to the portfolio
– high rise building break-out cable – which provides a fast,
economical and convenient method of getting fibre to the
end user in multi-level construction applications. All of these
products are fully compatible with Prysmian’s G657 compliant,
bend insensitive fibre – CasaLight™.
