            Special demands are made on the braided shielding in
            torsion cables. Torsion-optimised shield structures are
            chosen that allow compensatory movements thanks to
            special PTFE gliding films.

            With twistable bus cables in particular, the transmission
            characteristics such as attenuation, cable capacitance
            and signal quality must remain within very tight tolerance
            ranges over the whole service life. This is achieved
            through the use of particularly torsion optimised
            insulating materials and mechanical attenuation elements
            with matching capacitance values.


            The highly abrasion-resistant, halogen-free and flame-
            resistant PUR jacket material in motor, hybrid/control
            cables and bus cables protects the torsion-optimised
            stranded elements from possible damage.
            The highly abrasion-resistant, halogen-free TPE jacket
            achieves the special requirements of the twistable FOC
            and individual as well as the single core cables.

            Unlike cables for linear e-chain systems , the mechanical
            stress on these cables is in the combination of bending,
            torsion and centrifugal forces that cannot usually be
            determined by design or during use by means of
            measurement. For this reason, and unlike the situation
                             ®
            with linear e-chain  applications, a clear “yes/no”
            statement cannot be made about the use of a particular
            cable in torsion applications.
            To enable evaluation to take place, based on sensible
            and comparable test results, the igus  “torsion test
