Product Description:
The RKL4604 power cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. The assembly is intended for motor-side power distribution inside automated machinery, linking Rexroth servo inverters to moving axes and auxiliary devices. By integrating three-phase conductors with smaller signal pairs in a single sheath, the cable simplifies routing through drag chains and reduces the number of required cabinet penetrations while preserving the electrical integrity needed for high-frequency, pulse-width-modulated drive outputs.
The conductor set is 4 × 4.0 + 2 × (1.0) + 2 × (1.5) mm², so the main phases carry current through 4 mm² copper conductors while dedicated pairs support sensors or brakes. At 20 °C, the loop resistance remains at 4.95 Ω/km, limiting voltage drop on long machine runs. The mutual capacitance is 0.8 nF/m, which controls discharge currents from fast-switching inverter edges. Power cores and control pairs share a rating of 600 V AC, allowing mixed-function wiring inside the same jacket. Installation in a drag chain requires a minimum dynamic bend radius of 7.5 × D, which helps limit conductor stress during continuous travel.
Flex endurance reaches 5,000,000 cycles when the cable is guided in energy chains. For fixed routing, the minimum static bend radius decreases to 5 × D, enabling tighter cabinet layouts without compromising the insulation. The outer sheath is made from a PUR compound with an adhesion-free, matte finish, and its bright orange color (RAL 2003) makes motor power feeds easier to identify. Continuous exposure to temperatures as low as -30 °C is permitted, so the assembly can be installed in refrigerated production lines before power is applied. The PUR jacket also resists cutting fluids and weld spatter commonly encountered near assembly robots.
