Product Description:
The RKL4705 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It routes three-phase motor currents, protective earth and auxiliary signals between drive controllers and IndraDyn or MSK servomotors, providing a single bundled harness that streamlines cabinet wiring and reduces installation time in automated machinery.
The cable’s overall diameter measures 14.8 mm, a size that balances current-carrying capacity with ease of routing through drag chains and cable trays. Each power core has a cross-section of 2.5 mm², while the assembly includes 4 (3+PE) power conductors so phase and earth leads share identical insulation geometry. Distributed capacitance is limited to 0.7 nF/m; lower capacitance minimizes reactive current and helps servo drives meet EMC limits at high PWM switching frequencies. At 20 °C the copper paths present a resistance of only 7.98 Ω/km, keeping voltage drop negligible on long machine axes and ensuring torque accuracy during rapid load changes.
For dynamic routing the RKL4705 is verified for 5,000,000 bending cycles inside an energy chain, matching the service life expected of linear modules in 24/7 production. When fixed the cable may bend to 5 × D; during motion the permitted radius is 7.5 × D, protecting insulation and shielding from mechanical fatigue. A tough PUR outer jacket resists cutting oils and weld spatter, while the RAL 2003 orange color maintains visibility in crowded cable ducts and conforms to international safety coding for power circuits.
