Product Description:
The RKL0027 motor power cable is manufactured by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. Designed for servo-axis installations, this cable carries the three-phase supply, protective earth, and auxiliary control cores between a drive controller and a moving motor. Its application space is automated machinery that uses drag chains or robotic joints, where sustained flexing and electrical noise immunity are both mandatory.
The outer diameter is 18.5 mm, a size that balances current-carrying capacity with routing through standard cable trays. Four power conductors with a cross-section of 4x6.0 mm² handle typical servo currents while limiting voltage drop over long runs. Independent auxiliary pairs, sized at 2x1.0 mm² + 2x1.5 mm², are reserved for brake release or temperature sensor lines and keep these low-level functions separate from the main phases. A Total Shield surrounds all cores, providing continuous 360° coverage that attenuates drive-generated electromagnetic interference and protects feedback signals travelling nearby. Mechanically, the construction is verified for 5,000,000 bending cycles, so the cable can operate in high-duty energy chains without early conductor fatigue.
Environmental resilience is provided by a PUR outer jacket that is matt, low-adhesion, and resistant to industrial oils. Conductor insulation can reach a continuous temperature of +80 °C without degradation, allowing higher motor winding temperatures before derating becomes necessary. When installed statically, the cable tolerates ambient temperatures down to -30 °C, and dynamic layouts observe a minimum bend radius of 7.5 × D to preserve shielding integrity. The jacket is colored RAL 2003 orange for clear identification in control cabinets and on moving axes, aiding maintenance personnel in tracing power paths during commissioning or service.
