Product Description:
The RKL4476 motor power cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. Designed for servo drive installations, this cable delivers three-phase power and auxiliary signals to moving motors in production cells, pick-and-place gantries, and tooling axes. Its construction supports continuous motion, tight routing, and electromagnetic compatibility so that machine builders can run long cycles without signal degradation or mechanical fatigue. The model integrates power, control, and protective earth conductors under a common sheath, reducing wiring time and minimizing joints inside control enclosures.
The outer sheath is formed from PUR, a thermoplastic polyurethane that resists abrasion, coolants, and weld slag, allowing the cable to operate in harsh factory environments. Because the insulation system is Halogen-Free, combustion gases remain low in corrosivity, reducing damage to nearby electronics during a fire. Identification in crowded cable trays is simplified by the distinctive RAL 2003 (Orange) jacket tone. Electrical losses are limited by a conductor resistance of 1.91 Ohm/km measured at 20 °C, supporting stable voltage along distributed axes. The three power cores each use a cross-section of 10.0 mm², enabling the line to carry high continuous motor currents without overheating.
Two signal pairs, specified as 2x1.0 mm² + 2x1.5 mm², are laid between the power conductors for temperature sensors and brakes, with a nominal capacitance of 1.0 nF/m that keeps feedback circuits within typical drive tolerances. Mechanical endurance is proven by 5 million drag-chain bending cycles, so the cable remains reliable in continuously reciprocating axes. For static runs the minimum bend radius is 5 × D, while dynamic routing requires only 7.5 × D, permitting compact cable tracks and short loop lengths in modern machine frames.
