Product Description:
The RKL0073 is a motor power cable manufactured by Bosch Rexroth Indramat for use within the RKL Motor Power Cables series. This cable links drive controllers to synchronous or asynchronous motors, carrying three-phase power and protective earth in automated machinery. Its design supports continuous-motion applications where the cable must endure repeated flexing inside drag chains and along articulating axes, making it a critical component of electromechanical actuation loops on assembly lines, material-handling systems, and gantry stages.
The conductor bundle has an outside diameter of 25.5 mm, so routing space inside energy tracks and cabinet glands must accommodate that envelope. Each power core has a cross-sectional area of 16.0 mm², providing the current-carrying capacity required for medium-frame servo motors without excessive voltage drop. A jacket made from PUR that is adhesion-free and matte resists coolants, lubricants, and abrasion; its surface stays clean and slides easily against guide channels. For quick visual identification, the sheath is orange (RAL 2003), matching international safety conventions for energized motor wiring. The copper conductors can withstand a continuous conductor temperature of 90 °C, so the cable can operate near warm motor housings and inside densely packed enclosures without losing dielectric strength.
The flex-rated core assembly survives up to 5,000,000 bending cycles, and it maintains electrical integrity when bent dynamically to a radius of 7.5 × D. During static installation, the minimum bend radius is 5 × D. Factory-terminated ends simplify connections: the motor side is fitted with an RLK3101 clamp box, while the drive side carries a keyed RLS0723 plug connector. The cable is halogen-free to minimize toxic gas emissions during a fire. Its drag-chain compatibility permits continuous motion without corkscrewing or cracking the jacket.
