Product Description:
The RKL4418 belongs to the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. This flexible assembly routes three-phase power and auxiliary control lines from drive amplifiers to synchronous motors, ensuring low-loss energy transfer and reliable brake control in automated production cells, robots, and material-handling equipment.
This cable measures an outer diameter of 29.8 mm, which defines gland and drag-chain sizing. Four power cores of 4x25.0 mm² carry the main motor current, while separate control pairs of 2x(2x1.5) mm² support brake release or temperature sensors without additional harnesses. A tough PUR jacket resists oil, abrasion, and welding splatter, and the colour code RAL 2003 (orange) flags the assembly as live power according to machinery-safety guidelines. Over the full length, a Total Shield attenuates EMI so that servo feedback channels remain immune to switching noise in high-frequency drive environments.
The copper conductors limit longitudinal voltage drop to 0.78 Ω/km, allowing long motor runs without retuning current loops. Thermal ageing is controlled by a maximum wire temperature of 90 °C, which matches the insulation class of Rexroth stator windings. Dynamic applications are supported by a flexible bending radius of 7.5 x D; when laid permanently the radius may tighten to 5 x D, and the construction is certified for continuous motion inside drag chains. An orange jacket simplifies visual tracing during service, and the assembly is rated for operation wherever shield continuity and mechanical protection are required.
Wake Industrial stocks this cable, can arrange same-day shipping for urgent builds, and keeps quotations valid for 30 days to streamline maintenance planning.
