Wire & Cable ASIA – July/August 2010 41
To remain competitive, data and communication cable manufacturers need production equipment that saves energy and
reduces consumption of raw materials and consumables. Maschinenfabrik Niehoff has developed a range of machinery to
meet these requirements.
The double-twist stranding machines of the DSI series (DSI 631 and DSI 1001) are built for a wide conductor cross-section
range and a maximum strand diameter of 8.5mm or 15mm. The lay length can be freely adjusted within a very narrow
tolerance band; the lay length consistency is < ± 0.5% of the effective lay length.
The DSI machines are equipped with Class IE2 energy-saving AC motors with electronic control, and correspond to the
current safety regulations of the machinery directive RL 2006/42/EG. Characteristics of the DSI stranders (available in left-
and right-hand versions) are the single bow design – which results in a significantly reduced energy consumption and noise
emission – and a contactless machine data transfer, which reduces maintenance
as well as operational and material costs to a minimum. The DSI machines
can be combined with other systems such as double-twist back twist payoffs,
longitudinal tape payoffs and pre-twisters. Depending on line configuration up to
three foils can be applied on the cable under controlled film tension. For certain
applications a double-twist back twist payoff can be applied.
Optionally the double-twist back twist payoff can be used to enable a triple
twist stranding process. In this way the stranding speed and therefore the
production capacity can be considerably increased and – as a consequence –
the production costs can be reduced.
DSI machines can be integrated into stranding lines to manufacture all types of
data and communication cables, including LAN cables of all existing – and even
future – categories.
