Product Description:
The RKL4536 motor power cable is produced by Bosch Rexroth Indramat as a member of the RKL Motor Power Cables series. Intended for servo-axis installations, it carries three high-current phases, protective earth and sensor leads between a drive and its motor. The assembly is built for continuous motion in automated handling cells, machining centers and packaging lines where energy chains guide cables through constant acceleration. An extruded jacket and finely stranded copper conductors support electrical reliability while resisting the mechanical stress found in tight-radius routing.
Mechanical life is defined by 5 million guaranteed bending cycles, so the cable remains serviceable through long production runs. During dynamic operation it may coil down to a minimum flexing radius of 7.5 x D, allowing compact drag-chain layouts; static routing can tighten further once clamped. With an outside diameter of 22.2 mm the bundle fits standard chain pockets, and its halogen-free PUR sheath resists abrasion, coolants and welding spatter. The sheath is color-coded RAL 2003 (orange) to match international safety conventions for motor power circuits and facilitate quick identification during maintenance.
A fixed installation requires only a 5 x D bend radius, reducing cabinet space when the chain is absent. The copper path of each power core offers a DC loop resistance of 1.91 Ohm/km, supporting accurate voltage delivery over long axes. Internal geometry follows the composite layout [4x10.0 mm² + (2x1.0 mm²)StC + (2x1.5 mm²)StC]C; the first group comprises four power cores, each with a cross-section of 10.0 mm², while the paired shielded control leads measure 1.0 mm² and 1.5 mm² respectively. This combination provides balanced current capacity, low signal interference and full compatibility with drag-chain rated connectors.
