Product Description:
The RKL4625 cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It is a multi-core assembly that delivers mains power and low-level control lines from a drive to a servo motor through the motor’s terminal box connection. By combining power conductors with paired control cores in a single jacket, the cable helps streamline cabinet wiring and maintains electromagnetic compatibility in industrial automation systems that require synchronized motion and compact routing.
The three-phase power circuit uses a cross-section of 35.0 mm², allowing the cable to carry the current demanded by high-torque servo axes while limiting thermal rise. Copper losses are further minimised by a conductor resistance of 0.554 Ω/km, which reduces voltage drop along extended cable runs. An overall diameter of 30.8 mm determines the required gland size and informs cable-tray spacing. For dynamic machine elements, the flexible installation bend radius is 231 mm; in static routing the radius can be reduced to 154 mm. The PUR outer sheath withstands oils and abrasion, while the 300 V control cores are segregated from the high-energy power conductors to satisfy insulation coordination.
Built from the bulk cable type INK0667, the RKL4625 is rated for system supplies up to 300/500 V between conductors and earth. The four power conductors are complemented by control wiring arranged as 2 pairs of 1.5 mm² that support temperature sensors or brakes without additional harnesses, and the assembly presents a specific capacitance of 1.2 nF/m to the drive, a value that shapes reactive current at high switching frequencies. Continuous operation is permitted up to a conductor temperature of 90 °C, and the highly visible outer jacket in RAL 2003 (Orange) aids identification in crowded drag-chain installations. All terminations are made in the motor terminal box, completing a shielded, oil-resistant link from cabinet to machine.
