Product Description:
The RKL4428 is a motor power cable from the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. It links servo drives to motors in automated machinery, combining power delivery with auxiliary conductors so that temperature sensors or brake circuits share the same routed harness. The cable is engineered for continuous motion and harsh industrial environments where electrical integrity and mechanical robustness are critical.
The three-phase cores provide a cross-section of 10.0 mm², enabling low-loss transmission of motor currents at a rated supply of 600 VAC. A separate control bundle inside the sheath is specified for up to 300 VAC, isolating feedback or brake power from the main conductors. Overall diameter reaches 22.2 mm, yet the flexible PUR jacket remains matte and adhesion-free to reduce cable stick-slip in energy chains. This sheath resists oils and weld spatter, while its bright RAL 2003 orange colour maintains visibility in crowded cable runs.
Mechanical limits are defined by a fixed bending radius of 5 × D and a dynamic radius of 7.5 × D, allowing reliable operation in long-travel drag chains where repeated torsion occurs. Typical mutual capacitance is only 1.0 nF/m, minimising reactive current at high PWM frequencies, and conductor resistance is held to 1.91 Ω/km at 20 °C for efficient voltage delivery over distance. The pair of 1.0 mm² and 1.5 mm² auxiliaries supports thermal sensors or brakes, and drag-chain suitability ensures the PUR sheath withstands millions of cycles without cracking.
