Product Description:
The RKL0068 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It provides the power link between a drive and its servo motor inside automated machinery, where consistent voltage delivery and mechanical longevity are required.
Rated for an operating voltage of 600 V AC, the cable can be deployed on standard low-voltage motor circuits. The copper conductors have a cross-section of 4.0 mm², a size that balances ampacity with flexibility for compact routing. At 20 °C the conductor resistance is 4.95 Ω/km, a value that limits I²R losses over typical machine lengths. Discharge capacitance is specified at 0.8 nF/m, so drive output filters can be sized with predictable reactive loading. Mechanical durability is reinforced by a drag-chain design that endures up to 5,000,000 bending cycles without jacket failure. This voltage category also interfaces safely with 400 V class inverter outputs, helping maintain insulation margins during switching transients.
For motion axes that pivot or slide, the dynamic bending radius requirement is only 7.5xD, while static installations may be set at 5xD; these ratios allow tight cabinet layouts. The jacket is coloured RAL 2003 (orange) for clear identification of power circuits and is moulded from a matte, adhesion-free PUR that resists oils and weld spatter. When clamped in fixed routing the conductor insulation tolerates temperatures up to +90 °C, and it remains operational at +80 °C during continuous flexing. Combined with drag-chain approval, these features make the cable appropriate for line-mounted robots, conveyors, and modular production cells that require frequent movement without electrical degradation.
