Designed with a smaller outer diameter to save space and weight
Cost-saving due to the use of smaller drums, guide rollers, as well as drive engines when possible
Reeling, unreeling and guiding operations also impose tensile stresses on the cables
The central supporting element absorbs the tensile loads that occur, thereby allowing reeling, unreeling and deflection for free-hanging cables even over large distances.
Integrated supporting braid prevents undesirable cable twists, and the formation of so-called corkscrew effects
