Product Description:

The RKL0025 cable belongs to the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. It delivers three-phase motor power in automated systems where axes move continuously inside cable carriers and articulated joints. By linking Rexroth drive controllers to servomotors, the cable maintains electrical integrity and mechanical reliability during high-cycle production.

The cable endures 5 million bending cycles, so the conductors and insulation withstand prolonged reciprocating motion without fatigue. During movement the minimum loop size is limited by a 7.5xD dynamic bending radius, meaning an installation with the 14.8 mm outer diameter can flex to roughly 111 mm. Its PUR jacket is adhesion-free and matte, resisting oil and weld spatter while reducing stick-slip inside carriers. Electrical losses stay low because the copper bundle exhibits a 7.98 Ohm/km conductor resistance at 20 °C. Four power cores terminate on a Clamp Box RLK1201 at the motor and a Plug Connector RLS0747 toward the cabinet.

When routing is stationary the design allows a 5xD static bending radius, suiting tighter service loops on test stands or gearboxes. Fixed installation can tolerate conductor temperatures up to 90 °C, whereas flexible operation is limited to 80 °C to preserve insulation life. Mass calculations are straightforward because the cable contributes 0.380 kg/m to moving assemblies, information used when setting servo acceleration limits. Confirmed drag-chain compatibility lets the molded strain-relief segments slide smoothly through carrier links without jacket cracking.
