Product Description:
The RKL0034 cable belongs to the RKL Motor Power Cables series produced by Bosch Rexroth Indramat. It is specified for routing power and auxiliary control signals between servo drives and motors in automated machinery where continuous flexing, tight routing spaces, and electrical noise mitigation are critical. By combining power conductors with paired control cores in a single assembly, the product simplifies wiring in moving machine axes and robotic joints.
The cable’s overall diameter is 25.5 mm, giving panel builders a clear reference for gland selection and drag-chain clearance. Current is carried through a 4x16.0 mm² + 2x(2x1.5 mm²) stranded copper layout that separates motor phases from encoder or brake lines. DC resistance of 1.21 Ω/km limits voltage drop on long runs, while the power cores tolerate up to 300/500 V in fixed or dynamic operation; the paired control cores are rated 300/300 V. For installation inside energy chains, the manufacturer prescribes a minimum bending radius of 7.5 × D, allowing repeated motion without conductor fatigue. The bright RAL 2003 orange jacket supports quick visual tracing in busy cabinets.
Mechanical life is extended by a test rating of 5 million bending cycles, so the cable suits high-duty linear axes. Fire-load reduction is achieved with a halogen-free design that limits corrosive gas release during combustion, an important safety feature in enclosed production areas. The mantle is extruded from PUR with a matte, adhesion-free surface that resists oil, coolant, and weld spatter while sliding smoothly in guides. A capacitance of 1.2 nF/m defines the reactive load presented to the drive inverter and influences permitted cable length. Together with the specified discharge capacity, jacket colour, and conductor voltage ratings, these characteristics establish a balanced cable for dynamic motor power delivery and signal integrity.
