Product Description:
The RKL0036 cable is a factory-assembled motor power lead manufactured by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It carries three phase conductors and a protective earth line from drive amplifiers to synchronous or induction motors used in automated machinery. By providing prequalified insulation, shielding, and strain-relief hardware, the assembly simplifies installation tasks on robots, gantries, and conveyors where constant motion subjects cabling to fatigue. Its role is to maintain consistent power delivery while matching the mechanical dynamics of moving cable chains.
It is rated for 5 million bending cycles, indicating the number of articulated strokes it can withstand before conductor or jacket degradation becomes likely, a requirement for high-duty drag-chain routing. A Total Shield of braided tinned copper surrounds the core bundle to suppress conducted and radiated noise between inverters and feedback devices. The termination zone accepts an M40 × 1.5 EMC cable fitting, so cabinet bulkheads can maintain continuity of the shield. Thermal aging is limited by a maximum conductor temperature of +80 °C, which defines allowable steady-state current based on installation ambient. For stationary runs, installers must respect a minimum bend radius of 5 × D to avoid compressive damage to insulation layers.
When the same lead travels with moving axes, the permissible dynamic curvature increases to 7.5 × D, giving designers a clear separation between static clamping points and mobile carriers. The cable’s overall width is controlled by an outer diameter of 25.5 mm, allowing gland plates or energy chains to be dimensioned accurately. An Orange (RAL 2003) polyurethane outer layer promotes quick visual identification of power circuits, while the PUR jacket resists oil, coolant splash, and abrasion. Internally, the conductors are pre-marked 1, 2, 3, and GNYE, reducing wiring errors during field replacement.
