New pair shielding for igus servo cables

igus cable specialists conducted four years of
development and testing to achieve easy processing of cables and simple
installation of complex pair shields while increasing the service life of the
energy chain at the same time. The result is a new pair shield for chainflex
servo cables of the CF 21, 27 and 29 series. This ensures maximum
electromagnetic compatibility of the control pair and faster shielding of the
cable, enabling users to save up to 30% of the processing time for the pair
shield as well as installation costs.

Servo cables are used to connect the converter and
drive. For their assembly, the user must first strip the cable using the CFRIP
thread – an innovation introduced by igus in 2012. The tear-proof ripcord in
the cable jacket makes the pulling easy, like a zipper, providing up to 50
percent faster cable stripping. The covered shielding increases the
electromagnetic compatibility of the control pair and simplifies the connection
of the pair shield. This allows users to save up to 30% on the installation of
the pair shields and therefore reduce costs.

“This special covering method significantly
increases the service life of the servo cable families,” explains Rainer
Ršssel, head of chainflex cables division at igus. “We were able to prove
this in the test in the in-house test laboratory with more than 45 million

cables with 36 months’ guarantee

The UL-approved igus servo cables of the CF21 series
are available with a highly flexible, oil-resistant PVC jacket for high
stressing capacity and the smallest bend radii in the energy chain of down to
7.5 x d. The CF27 cable series with an oil-resistant PUR outer jacket is
flame-retardant and has the EAC and CTP certificate for the Russian market, whereas
the CF29 cable with a TPE outer jacket is suitable for applications with a bend
radius of down to 6.8 x d, even at extreme temperatures of -35 to +100 degrees

All 1,350 or more chainflex cables for the movement,
available from Treotham, are tested by igus in the 2,750-square-metre in-house test
laboratory. This makes igus the only manufacturer on the market to offer a
36-month guarantee on its entire cable range.
