Product Description:
The RKL4598 is a motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is supplied to connect servo drives to synchronous motors, delivering phase current and protective earth in automated machinery. The construction and pre-assembled contacts simplify installation, while the mechanical design supports continuous motion typical of drag-chain or robot applications.
This cable is rated for 5,000,000 bending cycles, indicating the number of flexing movements it can endure before conductor fatigue becomes critical. Supplied in the Basic model class, the jacket and shielding materials follow the standard RKL structure without additional torsion features. A conductor cross-section of 25.0 mm² allows high current transfer with limited resistive losses, making the cable suitable for medium-power servo axes. When routed through moving energy chains, the dynamic bending radius must be at least 7.5xD to avoid compressive damage, whereas stationary loops may use a tighter static radius of 5xD. Together, these mechanical limits help designers size support trays and chain links so the copper strands and insulation remain within their elastic range.
The cable ships as a Ready-Made assembly, meaning plugs are crimped and over-molded at the factory to reduce wiring errors on the production floor. It is classified as a Power Cable, so only motor phases and earth are present; signal pairs for encoders are not included. Safe operation is permitted up to 80 °C ambient, while storage in control cabinets can reach the same maximum; performance is guaranteed down to -30 °C for both operation and warehouse conditions. These thermal limits allow installation in unheated facilities and high-temperature enclosures without premature insulation ageing.
