Easy, ergonomic and energy efficient
Producers of low voltage power cables will be among the first to benefit from the new MT105 multiwire drawing machines from SAMP. “This new range of machinery not only produces good quality wires,” says the company, “it also has excellent ergonomic features for easy operation,
it uses less energy, it increases overall productivity and uptime, while reducing downtime by simplifying maintenance.”
Some basic technical features are common to all MT105 models such as a maximum inlet diameter of 2.6mm, a number of different options for wire elongation (for example constant reduction or mixed elongation like 12 x 26% + 6 x 19%), and the number of wires that can be
drawn ranges from a minimum of 7 to a maximum of 56 (on 1, 2 or 4 rows up to
a maximum of 14 or 16 wires per row).
The MT105 is available in a ‘short’
draw-box version with 18 dies or a ‘long’ draw-box version with 22 dies. The long version consists of two separate modules with the first module equipped with its own independent motor. The latter configuration offers the following advantages according to SAMP:
• it enables the residual slip on the wire to be reset after the first module thus reducing the stress accumulated on the copper during the wire drawing process (this in turn will reduce the number of wire breaks in the downstream processes)
• it reduces the string-up time as it allows the wire to skip the first dies on the second module leaving the first one strung up (that is normally the worst part of the machine to string due to the large diameter of the wire); and
• it gives total flexibility in the management of the two modules.
To maximise the speed and production capabilities of the MT105 SAMP has developed the new R35M annealer. This is available in two versions – up to 5000 Amps or up to 7000 Amps. The annealer’s main design features are:
• zero speed annealing
• power from 2200–7000 Amps
• vertical annealer with long annealing path and leg
• DC annealer with high stability, ease of control and regulation
• water-cooled diode bridge
• water-cooled (quench) annealing shafts
• die less air wipe system.
The configuration best suited for the production of low voltage power cables
(a high number of flexible strands used in cross-sections of 6–500mm2) would be the MT105 with from 24 up to 56 wires on two or four rows of capstans with a maximum inlet diameter of 2.0mm and outlet range of 0.25–0.51mm.
As an example of the machine’s production capabilities, SAMP cites: “The 48-wire machine, equipped with a 7000 Amps annealer, is capable of producing about six tonnes per hour. Over one year (250 days of 24 hours) this would mean an output of 36,000 tonnes.”
