Product Description:

The RKL4636 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. This pre-assembled lead links IndraDrive amplifiers to synchronous motors, transferring three-phase power together with auxiliary conductors while remaining flexible enough for installation inside fast-moving drag-chain loops used in presses, gantries, and packaging machinery.

Internally, the conductors are arranged in a 4x6.0 + 2x1.0 + 2x1.5 mm² configuration; the larger cores carry the main motor phases, while the smaller pairs service brake release and earth continuity. A mechanical life of 5 million bending cycles qualifies the assembly for continuous-motion energy chains that reverse thousands of times each shift. With an outside diameter of 18.5 mm, installers can pass the cable through slim bulkhead glands without oversized knockouts, and a line resistance of 3.30 Ohm/km keeps voltage loss within drive tolerance on long axis runs.

The polyurethane jacket, supplied in RAL 2003 orange and formulated to remain adhesion-free, supports tidy bundling alongside pneumatic hoses. During wiring, a fixed bend radius of 5xD protects the copper cores from kinking, whereas dynamic routing in cable chains must respect the larger 7.5xD limit to preserve service life. The insulation system withstands a rating of 600 V AC and operates up to +80 C in flexible mode, while discharge capacitance of 0.8 nF/m limits common-mode currents that may interfere with encoder feedback lines.
