Application

The combination of feeder conductors with the conductors and the thermal protection in these cables is ideal. Precision servomotors, as used today in many areas of highly-automated manufacturing processes, call for high-quality, reliable and long-lasting cables. These requirements are met to a high degree by these cables. The cables have an additional overall shielding to ensure EMC compatibility, i.e. for protection against electromagnetic interference. They are manufactured based on specifications from leading manufacturers of servo drives and control systems, as well as in compliance with various VDE standards. They are used in the construction of machinery, plants and robots, and in automation, drives, control and production engineering, and in assembly equipment.
EMI = Electromagnetic Interference
To optimize the EMI features we recommend a large round contact of the copper braiding on both ends.

= The product is conformed with the EC Low-Voltage Directive 73/23/EEC and 93/68/EEC.

Properties

PUR outer jacket: low adhesion, extremely abrasion resistant, halogen-free, resistant to UV, oil, hydrolysis and microbial attack
Optimum compliance with requirements for electromagnetic compatibility (EMC) by approx. 85% coverage from the braided shielding
The use of polypropylene for conductor insulation means that thanks to the reduction in cable-related losses these low capacitance motor cables can have longer cable lengths between the converter and the motor than with comparable cables with PVC insulation
