Product Description:
The RKL4427 power cable is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. Designed as the fixed connection between an Indramat servo drive and its motor, it carries three-phase power and control conductors while withstanding the mechanical loads found in automated handling systems. In machine tools, packaging lines, and gantry robots the cable supplies regulated voltage and feedback paths so that the motion controller can govern torque, speed, and position without interruption. Its construction follows the company’s drag-chain class so dynamic routing is possible inside energy chains and moving carriages.
The cable survives up to 5,000,000 bending cycles inside continuous-flex tracks; meaning it can move back and forth that many times before conductor fatigue risk increases. With a drag-chain rating confirmed, it tolerates travel accelerations up to 10 m/s², allowing high-speed axis strokes without sheath tearing. The outer jacket is made of PUR, a polyurethane compound that resists oil, coolants, and abrasion, and its standardized color code of RAL 2003 (Orange) ensures quick identification inside control cabinets. Electrical performance is defined by a conductor resistance of 3.30 Ω/km at 20 °C, so voltage drop remains low on typical machine-length runs.
Internally the cable follows a 4x6.0 mm² + 2x1.0 mm² + 2x1.5 mm² layout, giving three equal-sized power phases with a dedicated protective conductor and paired control cores. Each phase conductor uses a 6.0 mm² cross-section to carry the required current for mid-range servo motors without overheating. Signal integrity during rapid switching is aided by a low mutual capacitance of 0.8 nF/m, which helps the drive maintain precise pulse-width modulation. At only 0.630 kg/m, the specific weight minimizes moving mass in drag chains, reducing drive energy and wear on carriage bearings during long duty cycles. The cable is halogen-free, limiting toxic emissions during over-temperature events.
