SERVO 9YSLCY-JB are flexible motor supply cables having special EMC-performance due to double shield, with low
capacitance design and PVC sheath. The cables feature UL-AWM approval for USA and Canada.
Construction 9YSLCY has a special concentric conductor array design, where protective conductor is split into 3 individual
cores with reduced overall cross-section. This design avoids that from all cable-relevant parts high frequency discharge
currents can pass lubrication film of motor bearings. This effect may damage motor bearings, especially if switching fre-
quency of the frequency converter is very high and/ or long cable lengths are required. This design also improves EMC noise
situation of the whole drive system. Contrary to usage of PVC insulated cables, PP insulated cables show significant reduc-
tion of useless reactive power always needed for charging and discharging the cable during operating of the frequency con-
verter. The cables are designed for use in dry, damp and wet conditions.
Construction 9YSLCY Black is UV-resistant and suitable for outdoor use inclusive direct burial. Approval terms of USA or
Canada don’t include outdoor use. At room temperature they are widely resistant to acids, alkali-resistant and resistant to
certain oils. They are suitable for free, non-continuously recurring movements without tensile load or compulsory guidance
and also for fixed installation. Furthermore the cables are flame retardant and self-extinguishing.
Application range:
Connecting cable between frequency converter and three-phase motors, with small and large sizes, in the range of paper
industry, chemical industry, heavy industry.
