Product Description:
The RKL4448 motor power cable belongs to the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. Designed for industrial automation, this preassembled lead carries three-phase drive energy between cabinet inverters and moving servo axes, while its construction ensures EMC compliance and mechanical resilience on high-cycle equipment. By routing power with minimal loss and supporting frequent motion, it bridges the electrical path from controller to motor in packaging lines, pick-and-place units and gantry systems.
Current handling starts with a power core of 10.0 mm², giving low resistive heating under rated servo currents. That conductor cross-section is matched with a resistance of 1.91 Ω/km, so voltage drop remains limited even on long traversing axes. The overall diameter measures 22.2 mm, permitting routing through energy chains without excessive fill. A sheath of PUR (adhesion-free, matte) provides abrasion resistance and rejects cutting oil, while its visible tone, coded RAL 2003 (orange), warns personnel of live power circuits. The cable also offers a discharge capacity of 1.0 nF/m to maintain predictable inverter filters.
Dynamic movement parameters differentiate the RKL4448 from static leads. A minimum bending radius of 7.5xD is accepted during motion, while stationary loops can tighten to 5xD without conductor fatigue. Endurance is verified for 5 million flex cycles, aligning with high-speed pick-and-place gantries that accelerate up to 10 m/s². The cable functions in drag chains from −20 °C to +40 °C during continuous motion and tolerates −30 °C storage or fixed routing, ensuring reliable start-up in chilled warehouses.
