The ÖLFLEX® SERVO 2YSLCYK-JB 3X50+3G10 from Lapp is a motor connection cable specifically designed for connecting frequency converters to electric motors. It is suitable for applications with medium mechanical stress and is used for both fixed installation and occasional movement. The cable is designed for use in dry, damp, and wet environments, with the black version also suitable for outdoor use, provided temperature limits are observed. The PVC outer sheath offers resistance to acids and alkalis, as well as conditional oil resistance. Flexible use is possible down to a temperature of -15°C.

Applications
The cable is primarily used in industrial electric drive applications, especially for powering large electric motors. It is designed for systems where high electrical power is transmitted and high electromagnetic compatibility (EMC) is required. The construction with earth-symmetrical cable design and tripled protective conductor reduces the formation of harmful currents at the motor bearing, which can extend the motor’s service life. Therefore, the cable is particularly suitable for systems where motor bearing damage should be avoided.

Functions and Features in Detail
The ÖLFLEX® SERVO 2YSLCYK-JB 3X50+3G10 features low-capacitance conductor insulation, optimized for long transmission distances. This minimizes capacitive losses and ensures stable signal transmission. The double shielding, consisting of an aluminium-laminated foil and a high-coverage copper braided shield, provides effective protection against electromagnetic interference. This shielding is crucial for EMC compatibility in industrial environments where many electrical devices operate simultaneously.

Technology Explained Simply
The designation 3X50+3G10 describes the cable construction: three conductors with a cross-section of 50 mm² each for power supply and three protective conductors with 10 mm² each, configured as a tripled protective conductor. This design ensures that currents in the protective conductor are evenly distributed, reducing the formation of currents at the motor bearing. The operating voltage is U0/U: 0.6/1 kV, sufficient for powering large motors. The PVC outer sheath is robust and resistant to chemical influences, making the cable suitable for various industrial environments.

Compatibility and Accessories
The cable is available as a 3+3 earth-symmetrical variant, making it especially suitable for applications requiring high EMC compatibility and motor bearing protection. It can be combined with frequency converters and electric motors designed for stable and interference-free power transmission. Use in combination with other components of the ÖLFLEX® SERVO series is possible, with the exact selection tailored to the specific requirements of the system.

Installation and Mounting
The cable is designed for fixed installation and occasional movement, making it suitable for systems with limited movement, such as production lines or conveyor systems. Mounting must consider mechanical and thermal load capacity. The cable should be installed in a way that the shielding is not damaged to maintain EMC properties. The cable’s flexibility facilitates installation in confined spaces or complex routing paths.

Operational Advantages
Using the ÖLFLEX® SERVO 2YSLCYK-JB 3X50+3G10 improves operational safety by reducing electromagnetic interference and minimizing motor bearing damage. The low-capacitance insulation ensures efficient power transmission over long distances, increasing system efficiency. The robust construction and chemical resistance of the PVC sheath ensure a long service life under industrial conditions. The cable is thus a reliable component in systems requiring high reliability and ease of maintenance.
