Submarine cable cutters
Petig’s cutter range was recently extended with the new HKS
8, designed for cutting submarine cables up to 240mm
diameter, depending on the armouring.
As with the other large cutters in Petig’s range, the cutters are
available with either a single– or a double–acting hydraulic
cylinder. Cutters with a double–acting cylinder have the
advantage that they can always be opened hydraulically, even
if, following a long period of use with the blades becoming
blunt, a stranded conductor or part of the armouring becomes
jammed between the blades.
The larger cutters, which cut diameters of up to 85mm and
110mm, are now made of solid aluminium, making them 35%
lighter. Cutter power has been increased and they are capable
of cutting through even stronger armouring.
Petig’s hydraulic cable cutters are usually driven by compact
hydraulic units, with a flow rate of between 1.75 l/min and
11.16 l/min. According to the type of cutter, the working
pressure varies between 250 and 600 bar. It is also possible to
activate the cutters with hydraulic hand- or foot-pumps.
The new HKS 8 has an additional pneumatic spring for easier
opening and closing of the cutter jaws.

Wire straightening
and cutting
Delisi Srl offers automatic wire straightening and cutting
machines for smooth and ribbed wires from 1mm to
20mm diameter. Delisi machines are versatile and can
be customised to suit the customer’s requirements.
Features include the hydraulic flying shear cut.
Feeding speed is regulated by hand-wheel or
electronically. Feeding rolls are never changed; with the
hand-wheel it is easy to select the grooves on the
feeding rolls for the diameter to work. The spinner has
a pre-regulated set of straightening jaws and it is said
to take only one minute to change the wire diameter.
The torsion is very reduced and the wire, after the cut,
is cold; tolerance on the bar length is less than ±1m.
An electronic programmer and one or three lines of
pneumatically tiltable arms can be supplied with the
rod collection bed; different lengths and different
quantities can be programmed and collected separately
in one of the lines of tiltable arms without stopping the
machine, giving the operator an opportunity to empty
the lower line of tilting arms.
