Nexans has further extended its Buflex range of
polyurethane sheathed reeling energy cables with
the addition of Buflex X’Prem, designed to boost the
performance and durability of cranes operating at high
speeds of up to 150 metres/minute.
Buflex X’Prem’s new design greatly improves the cable
in terms of traction and durability, without needing to
increase its size. The thinner and lightweight polyurethane
sheath enables it to offer similar performance to standard
rubber sheathed reeling cables, but within a smaller
overall diameter and enhanced abrasion resistance.
This enables crane operators and OEMs to utilise smaller
motorised reels to achieve equal or superior productivity.
Buflex X’Prem is available in both a low-voltage, yellow
version, for applications up to 1kV, such as in the general
industrial crane market and a medium-voltage, red or
black, version for applications from 6kV to 20kV in ports
and terminals.

‘What if’ is reality in cable
stranding and compacting
What if you only used diamond on the working surface of a die?
What if it became possible to make a Tungsten Carbide die with
a composite surface layer of extremely fine grain Polycrystalline
Diamond (PCD) on the working profle?
The cost would be a bit more than the plain Tungsten Carbide die,
but for compacting and stranding operations, the cable would
now see a PCD die, with all the benefits of greatly improved
surface finish and greatly improved wear resistance.
Now the ‘what if’ is real – thanks to Sanxin Wire Die. The dies are
called Nano-PCD Composites. The obvious applications are Cable
Stranding and Compacting operations.
Nano-PCD dies are readily available in diameters from 3mm
to 60mm. In compacting and stranding operations, they are
capable of processing 10 to 15 times the tonnage of the product,
compared with Tungsten Carbide dies. Result – the cables stay
within physical and electrical specification for much longer during
production and the surface finish is clearly superior.
Now you can easily justify using diamond dies for longer life and
better finish, in diameters where previously you could not even
think of using diamond.
