Product Description:
The RKL0028 is a motor power cable manufactured by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. Designed for fixed or dynamic routing between drive controllers and servomotors, the assembly delivers three-phase power together with auxiliary conductors that accommodate temperature or brake circuits. Its PUR jacket, orange for quick identification in control cabinets, offers abrasion resistance while maintaining flexibility, making the product suitable for continuous-motion axes and drag-chain installations in industrial automation.
The cable allows a static bend of 5 x D and a dynamic bend of 7.5 x D, where D is the outer diameter, ensuring conductor integrity during stationary or cyclic movement. With an overall sheath size of 12.2 mm, the assembly fits compact energy-chain cavities yet provides adequate insulation distances for its rated 600 V AC operating voltage. Internal make-up of 4 × 1.5 mm² power cores plus two shielded twisted pairs supports both motor phases and low-level sensor lines without separate harnessing, streamlining cabinet wiring and reducing electromagnetic coupling.
The copper conductors exhibit a resistance of 13.3 Ω/km, keeping I²R losses low over typical machine lengths, and a mutual capacitance of 0.8 nF/m limits reactive current at high PWM carrier frequencies generated by modern inverters. For thermal endurance, the wire insulation is rated to 90 °C in fixed routing and 80 °C under flex conditions, extending service life in warm enclosures. A matte, adhesion-free PUR jacket in color code RAL 2003 resists oils, weld splatter, and cleaning agents, while the specified construction minimizes kinking during repeated acceleration and deceleration cycles.
Wake Industrial stocks this cable and offers same-day shipping on qualifying orders, includes a 1-year warranty with every purchase, and keeps quotations valid for 30 days to aid maintenance scheduling.
