Product Description:
The RKL4640 belongs to the RKL Motor Power Cables series from Bosch Rexroth Indramat. It is a dedicated motor power cable that links IndraDrive and IndraDyn components to the mains, carrying three-phase supply and protective earth while withstanding continuous motion in drag-chain mounts. In automated machinery, this cable maintains stable power delivery to servomotors and prevents EMC-related faults through its differential design and integrated control pairs.
The polyurethane outer sheath supports up to 5,000,000 bending cycles, permitting long service life in high-duty energy chains. Electrical losses are limited by a conductor resistance of 0.554 Ω/km, which keeps voltage drop low over extended runs. A generous overall diameter of 30.8 mm accommodates the four main copper cores, each rated at 4x35.0 mm², so motors drawing high continuous current can be fed without excess heating. The PUR jacket also resists cutting oils and weld spatter, making the cable suitable for harsh production cells.
Signal routing is simplified by the paired control cores specified as 2x(2x1.5 mm²); these pairs can carry brake release or temperature signals without an additional harness. The cable’s distributed capacitance of 1.2 nF/m minimises reactive load on the drive output filters, and its fixed installation rating of +90 °C allows enclosure runs near warm power electronics. A highly visible sheath in Orange (RAL 2003) aids quick traceability inside complex cable trays, while PUR flexibility is preserved down to +80 °C in moving applications.
Wake Industrial offers a 1-year warranty on every RKL cable, can arrange international shipping options, and provides a free chat tool for general questions about type codes or fault indications.
