The ELM1-23W1-LSW-NN power cable is part of the ELM eLion Power Cables series from Bosch Rexroth and links inverters to electric motor pumps in hydraulic automation systems. It uses a single-core design that streamlines routing inside compact drive trains, and the conductor is made from stranded copper to balance flexibility with low electrical loss. A cross-section of 35 mm² supplies ample conductive area, while the matching 35 mm² contact size keeps joint resistance low at both ends. The cable carries up to 190 A continuously at 85 °C to support high current servo pumps, and its 600/1000 V rating suits typical low-voltage DC bus links. Electrical losses are limited by a resistance of no more than 0.527 Ω/km, helping maintain voltage stability over long runs. The red ELS-CN5*W* phase code provides clear phase identification during installation, and a minimum bend radius of four times the diameter prevents conductor damage in tight machine spaces.
The outer diameter is 12.7 mm with a ±0.3 mm tolerance, allowing accurate sizing of cable glands and drag-chain channels, and each meter weighs 0.44 kg, which informs load calculations on moving axes. Radiation-crosslinked copolymer insulation withstands thermal cycling near hydraulic power units, while a radiation-crosslinked polyolefin jacket resists oils and hydraulic fluids. A dedicated cable protection pipe shields the assembly against abrasion where it passes through steel frames, and it tolerates ±10 °/m torsion so that articulated joints can rotate without stressing the cores. The inverter side uses a straight connector in the standard position for quick docking, and the motor end is finished with a ring cable lug that mates directly to the drive stud. Power distribution inside the motor housing is handled by an M25 gland with an additional ring cable lug, and the terminal thread of M25 × 1.5 matches common hydraulic motor covers without adapters.
