Description

A copper conductor for power control cable

Technical Field

The utility model relates to the technical field of copper conductors, in particular to a copper conductor for a power control cable.

Background Art

Power control cables are used in fast-moving situations, such as drag chain systems, woodworking machinery, machine tool processing equipment, logistics and transportation systems, cranes, robots and robotic arms. With the advancement of technology, the application of power cables is becoming more and more extensive. For cables used in different scenarios, their key technical standards are constantly being updated to adapt to their increasingly complex environments.

The copper conductor of the power control cable is particularly important. The copper conductor inside is the core of the entire communication cable. At present, during the transportation and installation process, the internal copper conductor is often broken due to the folding of the cable. In daily use, it is not enough to be soft, but also has the necessary toughness. In the process of mobile use, the cable needs to withstand certain stress, tensile resistance, wear resistance, small bending radius, torsion resistance and other good mechanical properties. In order to obtain a power control cable copper conductor that can meet customer needs, we propose a power control cable copper conductor to solve the above problems.
