Product Description:
The RKL4443 is a motor power cable produced by Bosch Rexroth Indramat for use within the RKL Motor Power Cables series. Designed as the link between IndraDrive controllers and synchronous motors, the cable carries three-phase power while incorporating auxiliary cores for brake or sensor functions in automated machinery.
Electrical performance begins with the bulk cable type INK0604, which defines insulation and shielding layers that suit dynamic machine environments. The four power cores have a 6.0 mm² cross-section and tolerate operating voltages up to 300/500 V AC, while line-to-line capacitance of 0.8 nF/m keeps reactive load on the drive low. Copper conductors exhibit only 3.30 Ohm/km of resistance at 20 °C, limiting thermal rise during sustained current flow. Two paired control circuits share the sheath and provide 2x1.0 mm² + 2x1.5 mm² copper for feedback or holding-brake power, allowing a single routed harness to cover both high-current and low-current needs.
Mechanical properties aid installation reliability. The bright Orange (RAL 2003) outer jacket is moulded from oil-resistant PUR and is certified halogen-free to reduce corrosive gas generation during fire exposure. For trays or gantry chains that remain fixed, the cable can be routed around a radius of 5xD; in continuously moving drag-chain loops the minimum bend expands to 7.5xD to protect conductor strands. This flexibility combines with the 4-conductor power design to simplify routing through confined enclosures without exceeding stress limits on the copper cores.
Wake Industrial stocks this cable, can arrange same-day shipping when requested, and keeps quotations valid for 30 days to streamline procurement.
