Flexible drag chain cable is a subdivision of cable. As early as 70 years ago, Germany invented drag chain cable, but it is only applied in a few fields such as automobile manufacturing.
The reason why the flexible drag chain cable is special is that it is installed in the state of repeated bending movement, the use scene environment is bad and there are many uncertain factors, and the stable transmission of power supply and signal must be ensured.
In recent years, with the wide application of flexible drag chain cables in CNC machine tools, 3C equipment, food, packaging and other industries, the market has become the focus of the wire and cable industry.
However, it is a pity that there is no special standard for drag chain cables so far, because the formulation of the standard is a rigorous and time-consuming work, which often leads to serious delay in the introduction of the standard.
At present, the flexible drag chain cable standards of VDE, UL and CCC are still in the preparation and demonstration stage. The lack of authoritative standards leads to neither a unified naming method nor a unified testing method in the market; The quality can only depend on the manufacturer's own technical strength, which makes customers worry when choosing drag chain cables.
