Special cable for servo system connects and controls the operation of servo motor, which greatly improves the working efficiency of servo motor. Servo motor includes control motor and executive motor. Servo Cable has the characteristics of high flexibility, wear resistance, bending resistance, tensile resistance, torsion resistance, anti-interference and durability.
What are the national standards of Servo Cable?
The national standard of Servo Cable is GB/T 20266-2006 Servo Cable. This standard specifies the technical requirements, test methods and inspection rules of Servo Cable to ensure that Servo Cable can meet the relevant performance and quality standards in practical application. According to this standard, Servo Cable is mainly divided into the following aspects.
1.The conductor material of Servo Cable requires high conductivity and good mechanical strength. Generally, stranded copper conductors are used to ensure low resistance and high strength when cables transmit power. At the same time, the conductor should be flexible enough to facilitate the movement of the cable during bending and installation.
2.The insulating materials in Servo Cable require good insulating performance and chemical corrosion resistance. The insulating material should have sufficient electrical strength to prevent the cable from breaking down under high voltage. In addition, insulating materials should have good chemical corrosion resistance and can be used for a long time in harsh industrial environment.
3.The shielding structure and anti-interference ability of Servo Cable are also important contents in the standard. In order to prevent the influence of external
electromagnetic interference on signal transmission, Servo Cable usually adopts shielding structure, including conductor shielding and integral shielding. Conductor shielding is to cover the twisted copper conductor with a layer of copper foil, while the overall shielding is to cover the whole cable with a layer of copper mesh. Such a shielding structure can effectively reduce the influence of external interference on signal transmission and improve the stability and accuracy of the servo system.
4.The outer sheath material of Servo Cable should have good wear resistance and corrosion resistance. Because the servo system often needs to bend and move frequently, the outer sheath material of the cable should be able to resist mechanical wear and chemical corrosion and protect the integrity of the inner conductor and shielding structure.
The standardization of design and manufacturing in Servo Cable provides a reliable guarantee for the stable operation and efficient work of the servo system.
