Product Description:
The RL2-521CBT motor power cable is produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. This flexible assembly carries three-phase supply energy from drive amplifiers to second-generation synchronous motors in automated machinery. By combining finely stranded copper conductors with a torsion-rated jacket, the cable transfers continuous current and maintains signal integrity while machines execute repetitive, high-speed motion cycles in packaging lines, gantry axes, and other industrial automation devices.
The power conductors inside the cable have a nominal cross-section of 1.0 mm², giving a balance between current-carrying capacity and manageable outer size. They are rated for 600/1000 V, allowing connection to low-voltage inverters without additional insulation. Temperature endurance reaches +90°C when the installation is fixed, so routing through warm control cabinets does not shorten service life. During dynamic operation the cable follows a minimum bending radius of 7.5xD, and its sheath supports up to 5,000,000 flex cycles in torsional and chain applications. Insulation resistance is at least 20 MΩ/km, limiting leakage currents even on long runs. An overall diameter of 12.2 mm simplifies routing through standard energy chains while preserving mechanical robustness.
For moving axes the static portion of the harness can be anchored on a radius of 5xD, preventing strain where the cable transitions from stationary fixtures to energy chains. When motion is continuous, the flexible conductor class withstands ambient peaks of +80°C without insulation cracking. The outer jacket is moulded from PUR (Orange RAL 2003), a material chosen for oil resistance and visibility inside machines. Coupled with a low mutual capacitance of 0.4 nF/m, the design minimises reactive losses between motor phases and keeps drive feedback stable. The cable is tuned for the 2nd motor generation, and its torsion-optimised conductor stranding distributes stress evenly along the length to extend service life.
