Cortinovis
Machinery SpA
Stand: 11D40
Cortinovis Machinery SpA, part of Eurolls
Group and a leader in rotating machinery,
has supplied and commissioned cable
technology including such rotating
machines as the Rigid Strander and Drum
Twister for the production of high quality
Milliken copper conductors up to
3,000mm².
To fulfil the tight quality requirements of
such large cross section conductors,
several aspects of the stranding and laying
up processes required special attention and
specific developments.
Cortinovis Machinery supplied the 91 wire
rigid cage strander with updated technical
solution on the renewed rotating
compacting head for the production of the
pre-spiralled sector shape copper
conductor up to 600mm2. The new
self-centring compacting heads have
proved its capability of producing high
quality pre-spiralled sector shape
conductor essential for reaching the
approval of the cable quality control test
system.
The package includes the Drum Twister
machine, capable of receiving large, heavy
bobbins up to 4,500mm in diameter –
among the largest machines of its type
supplied worldwide – with high pull
self-centring belt caterpillar type able to
lay-up five or six pre-spiralled sector shape
copper conductors and round centre, with
the very tight diameter tolerance typical of
extra high voltage cable conductors. The
turnkey supply included not only the cable
design but also the supply of all necessary
shaped rollers and dies for the new rotating
compacting heads needed for the full range
of cables.
The new generation Cortinovis Machinery
package includes not only the Rigid Cage
Strander and Drum Twister with different
sizes, but also the cable design and, upon
request, the process engineer to ensure
success of the investment. It is addressed
not only to cable makers that intend to
extend their production range, but also to
newcomers wishing to produce Milliken
conductors ranging from 1,600 to 3,000mm².
