Product Description:
The RKL4574 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed as a hybrid supply lead for synchronous motor installations, it carries three-phase power and auxiliary control signals from the drive controller to the machine tool or robot arm. In automated production lines it maintains electrical integrity under dynamic movement, acting as a critical link between drive electronics and the actuating motor.
Four power conductors with a cross-section of 4 x 16.0 mm² deliver the main motor current, while a separate bundle of 4 x 1.5 mm² control cores feeds brakes or sensors. A low conductor resistance of 1.21 Ω/km limits voltage drop across long routes, supporting accurate torque production. When the cable is installed statically it only requires a fixed bending radius of 5 x D, and the construction endures up to 5 million bending cycles, allowing it to outlast high-duty indexing tables and gantries.
For mobile axes inside carriers, the permissible routing radius enlarges to 7.5 x D to avoid conductor fatigue. Dielectric behavior is characterized by a discharge capacity of 1.2 nF/m, keeping drive-side filters inside specification. The outer sheath is molded from PUR, giving abrasion resistance, coolant tolerance, and flame retardancy, and it is colored RAL 2003 orange for quick identification. Continuous operation remains safe up to a conductor temperature of +80 °C; combined with approval for drag-chain use, the cable supports high-speed pick-and-place axes without undue stress on wiring.
Wake Industrial stocks this cable and offers a 1-year warranty with every purchase. Same-day shipping is available when orders are placed before the daily cut-off. Customers can use the free chat tool for general questions about type codes or electrical parameters.
