Product Description:

The RKL4586 is a motor power cable manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It connects drive controllers to synchronous or induction motors in automated machines, supplying three-phase power and auxiliary signals through a single routed line. By combining main conductors and signal pairs inside one engineered jacket, the cable simplifies installation, shortens panel assembly time, and maintains signal integrity in dynamic industrial environments.

The power core of the cable has a cross-sectional area of 25.0 mm², providing a low-impedance path that keeps voltage drop within drive tolerances over typical machine lengths. The insulation withstands up to 600 V, so the assembly connects directly to most industrial inverter outputs without additional conduit. Copper conductor resistance is only 0.78 Ω/km at 20 °C, which minimizes thermal rise during continuous current flow. The insulation system has a thermal limit of 80 °C, allowing operation inside control cabinets where ambient heat and conductor self-heating combine. An overall diameter of 29.8 mm balances current-carrying capacity with available routing space. The fixed bend radius must remain at or above 5 × D, while moving applications require a dynamic bend radius of at least 7.5 × D to avoid stressing the conductors.

The cable includes two shielded pairs of 2x1.5 mm² conductors for feedback or brake-release signals, eliminating the need for separate low-power harnesses. A durable PUR outer sheath provides resistance to oil and abrasion, while its high-visibility finish uses the color RAL 2003 to support identification within machinery. Continuous aluminum laminate and tinned-copper braid provide total shielding, reducing electromagnetic coupling between noisy motor phases and nearby sensor lines. In repetitive-motion routes such as gantry axes or robot arms, the flexible jacket withstands recurring movement while the shielding protects signal clarity.
