Assets of the robot trailing cables
The use of the robot trailing cables is particularly recommended for the continually high bending stress in the machine tool equipment and industrial robots. They are constructed to withstand more than 10 million bendings at a bending radius of 12 x outer diameter attained at displacement velocities of 2 to 3 m/sec and accelerations of up to 5 m/sec2. Special constructions and selected appropriate materials guarantee that the high requirements of the robot trailing cables are met.
Compared to the traditional PVC cables the robot trailing cables made by NEXANS have the following assets:
- The special PP, TPM and TPE insulation of the cores is unique for the excellent gliding properties of the cores even at high operating temperatures, thus guaranteeing an increased life in spite of high mechanical stress. This insulation is neither affected by crushings (contractions) nor by plasticizers respectively bleeding which may result in a brittle insulation. Apart from good heat resistance, those insulation materials, are extremely flexible when exposed to extremely low temperatures and embattlement and unusual rigidity do not occur even at temperatures as low as – 50 °C. The extraordinary quality of the mechanical properties like tensile high stress, high notch and abrasion resistance protect the conductor against permanent stress.
- The electromagnetic compatibility (EMC) is guaranteed by the screen construction with an optimised angle of inclination.
- The outer sheath made of a special polyurethane with its known resistance to low temperatures, oils, greases, lubricants and cooling agents is an ideal complement to the good properties of the insulation.
All included, this special cable concept is the result of a long row of complicated tests and it has meanwhile proved to be successful on the market. Important users like Baumüller, Bosch, Fanuc, Heidenhain, Indramat, Moog or Siemens are among our customers.
Special cables for daisy chains
More and more manufacturing automates and transportation systems are equipped with daisy chains which include the necessary connecting cables. Cables with special construction are absolutely necessary to guarantee the long-term and safe transmission of energy and data. These cables must meet the tough requirements like bending stress due to extended displacement and high displacement velocities. Our robot trailing cables with PP, TPM and TPE insulation and TPU sheath particularly meet the high electrical and mechanical requirements.
