Product Description:
The RKL4730 cable is part of the RKL Motor Power Cables series from Bosch Rexroth Indramat. Designed as the main power link between IndraDrive controllers and servomotors, it routes three-phase energy and protective earth in dynamic machine axes. The cable’s construction supports continuous flexing so that it can be installed in cable chains and robot arms within automated production cells.
Mechanically, the RKL4730 is rated for 5,000,000 flex cycles, allowing long service life under repetitive motion. Installation guidelines specify a minimum dynamic loop of 7.5xD and a fixed routing loop of 5xD; these radii protect the copper strands from fatigue. Each phase conductor offers a cross-section of 35.0 mm², providing ample current-carrying capacity for medium-power drives. Despite this gauge, the overall cable measures only 30.8 mm in diameter, keeping drag-chain fill factors low.
Electrical performance is defined by a conductor resistance of 0.554 Ohm/km, which limits voltage drop over long runs. The core bundle originates from bulk type INK0667 and is sheathed in a rugged PUR jacket that resists oil, coolant and abrasion. Visual identification is simplified by the high-visibility RAL 2003 (Orange) outer layer, matching standard safety colours for power wiring. Termination is factory–assembled with motor plug RLK1301 and controller plug RLS0724/K35, ensuring low-contact resistance and strain-relieved connections in IndraDrive systems.
